We also want someone who has strong systems design experience and good technical leadership skills. In terms of tech stack, it's mostly Python and Typescript, including nest.js Our interview process is pretty straightforward. There's a phone screen with our recruiter, then a culture fit/qualifying interview with my boss, a technical interview with a real-world problem (no leetcode), and finally a cross-functional team interview with myself and another engineering leader at my company. We move pretty quickly and aim to keep the process respectful of everyone's time. Happy to answer any questions here!

Quin | Founding Engineer (CTO for the right person) | REMOTE (US), preference for Bay Area (tech), Chicago (consumer), or NYC (finance) | Full-time Quin is an agentic platform to (finally!) solve personal finance for people. It is a consumer-focused company. https://iamquin.ai I spent 13 years in private banking and have been working on Quin alone for about 15 months. I built 6 different prototypes to test different approaches. I've spent the last few weeks working with testers on the latest version and solidifying GTM. I need someone to take over engineering with a focus on building the backend and data layers that will support our agentic approach to personal finance. Georgetown. UCLA (MBA). Ex-JPMorgan. Traction: Prototype with testers The role: You're the first engineering hire. This is about shipping the workflows that will become the product that users will trust and the data layer that can support an agent in the future. You'll own backend architecture decisions from day one. Contract-first development (TypeScript contracts repo as source of truth), FastAPI, Supabase/Postgres, Groq for LLM inference. The stack is clean and the codebase is small. Who I'm looking for: A full-stack engineer with a preference for backend. 5+ years backend engineering; Python / FastAPI preferred. Strong data modeling instincts — you've designed schemas that had to scale. Experience with multi-tenant data architectures. Comfort operating without process. Finance domain familiarity a plus, not a requirement. Comfort and experience using AI tools and incorporating new ideas quickly. For the right person, this is an opportunity to take a CTO/co-founder role and define the full technical path. Comp: Salary post-raise and meaningful equity. TBH, finding this role (either version) will be important for rasisng capital given that I do not have a technical background and fintech is complicated by regulations. I'm ok with part-time in the meantime if that's what it requires. Email quin@iamquin.ai with the primary reason this interests you and the top two reasons why you should be considered (don't worry about a resume at this point).

Opaxa | Founding Full-Stack Engineer | San Francisco | Full-time | $200K–$300K + founding equity | opaxa.ai Opaxa is the AI agent platform that runs restaurant back-office operations. Not another dashboard — agents that take the work off the operator's plate and act: build the schedule and push it to action, place the order with distributors, audit the invoice for overcharges, draft the review reply. The operator approves what matters; the rest gets done. The unfair part: the founder owns and runs a 40-location restaurant company with over 750 employee's — so Opaxa's first customer is a real, operating restaurant group with real data and real stakes from day one. Deep domain expertise is built in, and your work runs in real restaurants immediately, not after a six-month hunt for a design partner. Well-funded. A working prototype is already built. Now I'm hiring a founding full-stack engineer to take it from prototype to production: own the architecture, the agent runtime, the backend, and the integrations the agents act through (Toast, Paycom, Sysco, and more), set the technical bar, and grow the team behind you. You'd work directly with me — I own product, customers, and the domain; you own the AI and the build. We'd be hiring additional engineers and account managers within the first year. You're a fit if you: - have shipped agentic systems to production — plan-and-act, not chatbots or wrappers - are a strong full-stack builder (Python and/or Node, Postgres, real infra) - use the latest AI tooling (Claude Code / Cursor) as your default want to own a whole product as the first engineer, and eventually lead Stack: React/TypeScript, Python/Node, Postgres, the Anthropic API, integrations across the restaurant stack.

I've decided to no longer post here after the incredible amount of spam I started receiving, both in terms of direct email submissions as well as unqualified and outright fraudulent applications to my application tracking system. By fraudulent I mean: fake resumes, names stolen from real developers who work at well-known companies but either don't have a linkedin/portfolio or do have a linkedin/portfolio without a profile picture. So easily impersonated by a scammer. It is a real shame, but this thread is now being scraped by plenty of other sites and bad actors. Inbound hiring for remote teams is basically cooked at this point, signal is completely hidden in the noise. Curious if anyone else has had this experience or if it's just me?

Emergences Labs (emergences.ai) | AI / Systems Engineer — NeoHuman | REMOTE (US) | Full-time | $120K-$150K + equity | Visa sponsorship available We're a small, research-driven, VC-backed team building NeoHuman: a desktop-first system that observes how people actually use AI tools, files, and workflows during real tasks, and turns those sessions into reliable evaluation evidence. We care about the process, not just the final answer — what someone typed, what they copied, what they verified, how they moved across apps. We've published the AgentIF-OneDay benchmark. Now we're scaling the capture and evaluation infrastructure underneath it. You'd own: - Cross-platform desktop capture across macOS + Windows (AX/UIA trees, OCR, clipboard, keyboard/mouse boundaries, file interactions) - Trace fusion — turning noisy low-level signals into clean human-readable session timelines - The evaluation evidence pipeline (data model, ingestion, exports) - LLM normalization that summarizes traces without hallucinating or hiding evidence quality - Privacy/consent/proctoring safety for enterprise customers We want an AI-native engineer: - 3+ years shipping production TypeScript + Node.js - Built or shipped Electron + native helpers - Strong PostgreSQL (schema design, indexing, data quality) - Comfortable with OS APIs, permissions, background processes - Hands-on LLM API experience (structured output, evaluation, hallucination control) - Uses Claude Code, Cursor, or similar as a daily working medium — not a side experiment - Bonus: macOS AX / ScreenCaptureKit / CGEventTap, Windows UIA, or you've studied/built things like Screenpipe, OpenAdapt, Rewind, OpenChronicle Stack: TypeScript · Node.js · Electron · native macOS/Windows · Next.js 15 · React 19 · Postgres + Supabase · OCR · Accessibility APIs · OpenAI / Anthropic / Gemini · Vercel · GitHub Actions Why us: Hard, unusual problem at the boundary of OS internals, multimodal capture, and AI evaluation.

Hotwash | Founding Engineer (→ CTO for the right person) | REMOTE (US), Boston a plus | Full-time

Hotwash | Founding Engineer (→ CTO for the right person) | REMOTE (US), Boston a plus | Full-time I'm a solo founder. I built the entire product myself, got 11 fire departments paying with zero churn, and now I need someone to own engineering so I can't be the only one who does. West Point, Ranger Regiment, Yale Law, still the only developer. What we do: Hotwash is an after-action review platform for fire departments. After a serious call, crews record what happened, we transcribe and structure it, and the hard-won lessons become searchable institutional memory instead of retiring when the veterans who earned them do. Fire is the wedge; the long game is operational learning for any high-reliability organization. Traction: $40K ARR, 11 paying fire departments, zero churn. Raising a $1M pre-seed. The role: Employee #1 on engineering. You own the codebase, architecture, and UX end to end, and you lead the rebuild off the current stack. You work directly with me on what gets built and why, including sitting with fire chiefs to figure out what they actually need. For the right person this becomes the CTO seat. Who I'm looking for: A full-stack engineer who ships simple, usable products and has a real eye for design. Our users are fire crews, not power users, so the bar is "obvious to someone who's never seen it." If you care about how software feels, not just whether it works, this is your seat. Stack: Today it's FlutterFlow + Firebase, Node, with Groq/AssemblyAI for transcription and Gemini for summarization. The rebuild target is React Native (Expo), Cloudflare Workers, D1, R2. You'd own that migration, so this is real greenfield ownership, not maintenance. Comp: Founding equity, scaled to scope. We're pre-raise, so cash is lean right now and grows when we close.

Sentinel Defense Technologies | Remote (Global) | Equity → Pre-Seed Closing We build real-time civilian threat intelligence for conflict zones — and we just landed our first operational pilot. Multi-model AI pipeline (Gemini 3 Pro / Flash) ingests OSINT from verified sources, runs it through a gated verification system, and pushes geolocated alerts to offline-first mobile clients. Think of it as a personal intelligence analyst for non-combatants — on a phone that works on 2G. This is not a pitch deck. We have a working system: Django backend is live, Flutter apps are approved on both App Store and Play Store, multi-gate AI pipeline is processing real OSINT, admin console has human-in-the-loop verification for high-severity alerts. Since our last HN post: 93 candidates vetted across two months, 1 Senior AI/Backend Engineer hired (now owns the verification pipeline), and we've begun an operational pilot with Winrock International for counter-trafficking intelligence in Southeast Asia. Pre-seed is imminent with multiple NGO grant applications under review (WFP, IRC Airbel, DRK Foundation). *We need one person*: Founding Product Engineer / Systems Architect You will own the Django backend, MongoDB schemas, and the Flutter UI that connects them. Our AI pipeline lead handles the Gemini orchestration — your job is to own the data layer, build the API surface, and wire it directly into the offline-first client. This is not drawing backend diagrams. You must be an end-to-end builder who cares about how a civilian interacts with the system on the ground in a crisis. A bug in this system isn't a 500 error — it's a missed warning in a conflict zone. *Must have*: Python/Django, MongoDB, Flutter (or high competence to pick it up fast), and system design thinking. Strong plus: DevOps (Docker, AWS), LLM integration, OSINT, geospatial. We also welcome strong full-stack implementation engineers who ship fast and want founding-team equity. Same stack. *Compensation (No BS)*: - Now: Sweat equity (12-18% SA / 5-10% FSD, 4yr vest, 1yr cliff). This is founding-team ownership. - Pre-Seed (closing): $3,000/month + equity. - Seed (6-12 months): 75% market salary + equity. Increases from there. If you need full salary today, this is not for you. If you want to build something where the stakes are real and you're willing to bet on yourself to get there — we should talk. *Stack*: Python 3.9+, Django 4.1.13, MongoDB, Flutter, Antigravity/Cursor IDE, Docker, AWS. *Apply*: Email: PeterJFrancoIII@gmail.com with subject line `[SENTINEL-BUILDER] - HackerNews Application`.

Founding Full Stack Engineer

Marker Learning - Founding Full Stack Engineer – Remote (USA) – 180-250k

Marker Learning - Founding Full Stack Engineer – Remote (USA) – 180-250k I have dyslexia. I was one of the lucky ones. Diagnosed at eight, I got accommodations and support before things spiraled. Most kids aren't so lucky. The path from initial concern to diagnosis can take years and cost families upward of $5,000. For many, it never comes at all. In one study, 50% of prisoners were found to be dyslexic, with 80% functionally illiterate. Behind every missed diagnosis is a kid who gets told they're lazy, when the reality is no one ever gave them the right test. Marker Learning is building an AI-enhanced assessment platform that makes identifying learning differences faster, cheaper, and more equitable, especially for multilingual students who are routinely misidentified or overlooked. Imagine if every kid could be screened for learning differences as easily as they're screened for vision. That's what we're building. This isn't a chatbot or a homework helper. We're a Series B company backed by Reach Capital, Andreessen Horowitz, and Primary, running a multi-million-dollar longitudinal study spanning K–12 and developing the psychometric engine behind it. We need engineers who are excited by that. We're hiring a hands-on full-stack engineer (React, Node.js, TypeScript) to help build and scale the platform: adaptive testing infrastructure, AI-powered scoring scoring and data pipelines, and the systems that maintain clinical rigor at scale. High autonomy, lightweight process, fast-paced. 8–10+ years, ideally with 0-to-1 or early-stage experience. You'll work directly with psychometrics, product, and data science, and the engineering decisions you make now will define the platform for years. Reach out directly with your gh, linkedin, and resume and why you want this position to lucie@markerlearning.com. Please specify your location, if you are interested in full time, contract or open to both. Make the subject "Founding Engineer Application (I am not a bot)".

We're are small, fast teams that have gone deep on AI-augmented development. Not as a talking point; as the actual way we work. We prototype aggressively, put working software in front of stakeholders before a traditional process would finish a PRD, and iterate from there. We're looking for engineers who already work this way: driving agents on real codebases, maintaining quality when the machine is doing the typing, and knowing when to throw the output away. Stack: PHP (backend), React + TypeScript (frontend), MySQL, RESTful APIs, AWS. You'll work across the full stack. Senior (5+ yrs): Product-minded, systems-thinking engineers. You'd lead 1–2 engineers while still taking substantial features from concept to production solo. You mentor others in code design, systems thinking, and driving AI agents effectively. Mid-Level (2+ yrs): This is a senior-track role. You'll ship real features with mentorship from senior and staff engineers who are deeply invested in your growth. We want engineers who see where things are heading and want to get ahead of it; going deep on architecture, design, and understanding the problems, not just writing the code. Both roles: We want concrete evidence you use AI as a real tool, not a novelty. Push the tools until they fail, then tell us about it. We care about quality software that's easy to change, clear writing, and engineers who get curious about the customers, not just the tickets. Compensation: Salary TBD based on experience. Medical/dental/vision covered in full for the employee. Company-provided equipment. Apply with a brief resume and a cover letter (written or video — video goes to the front of the line).

Freight Brokerage

Founding Backend Architect

New2026-04hybrid: US, EST hoursunspecifiedequity/options

Freight Brokerage | NJ | Founding Backend Architect

Freight Brokerage | NJ | Founding Backend Architect (Python/PostgreSQL) | Remote (US, EST hours) | $150K + benefits We're a freight brokerage in NJ building a self-hosted, AI-first platform to replace our legacy CRM/TMS. The AI compute infrastructure and data foundation are already in place. We need the architect who turns it into a production operating system. This is a systems architecture role, not a feature dev role. If your primary strength is writing features or following tickets, this is not the role. You will be responsible for: designing and deploying a PostgreSQL schema for complex freight operations across 30+ entities. Building Python service layers integrating multiple REST APIs. Wiring locally-hosted LLM inference into business workflows. Structuring systems that involve document ingestion, email processing, and asynchronous event-driven pipelines. Defining backend patterns for reliability and maintainability across a multi-million record environment. The entire stack is self-hosted on custom-built server hardware. Database, application layer, AI inference — all of it. No cloud dependencies. No API rate limits. No monthly GPU bills. No vendor lock-in. You have direct access to the metal, you deploy on your terms, and the only ceiling on what you can run is the hardware itself. If you've ever wanted to build a production platform without a cloud provider standing between you and your infrastructure, this is that role. You are the first technical hire. You report directly to the owner, who is directly involved in this hire and in daily collaboration on the build. Architectural decisions are yours to make. AI coding tools and low-code UI frameworks are part of the workflow — your time goes to data models, service orchestration, and API plumbing, not hand-building screens. Stack: Python, PostgreSQL, FastAPI, Docker, Neo4j, Linux, vLLM. Preferred: freight/TMS domain, Microsoft Graph API, CRM migration experience. 1-week paid onsite onboarding in NJ, then fully remote. Equity conversation open once mutual fit is established. To apply, send: (1) your resume, (2) a brief writeup of a system you designed end-to-end — not code, but the architecture decisions you made and why, (3) a short note on why this role interests you. nj.technical.hire.spring.2026@proton.me

Sentinel Defense Technologies | Remote (Global) | Equity → Pre-Seed Closing

Sentinel Defense Technologies | Remote (Global) | Equity → Pre-Seed Closing We build real-time civilian threat intelligence for conflict zones — and we just landed our first operational pilot. Multi-model AI pipeline (Gemini 3 Pro / Flash) ingests OSINT from verified sources, runs it through a gated verification system, and pushes geolocated alerts to offline-first mobile clients. Think of it as a personal intelligence analyst for non-combatants — on a phone that works on 2G. This is not a pitch deck. We have a working system: Django backend is live, Flutter apps are approved on both App Store and Play Store, multi-gate AI pipeline is processing real OSINT, admin console has human-in-the-loop verification for high-severity alerts. Since our last HN post: 93 candidates vetted across two months, 1 Senior AI/Backend Engineer hired (now owns the verification pipeline), and we've begun an operational pilot with Winrock International for counter-trafficking intelligence in Southeast Asia. Pre-seed is imminent with multiple NGO grant applications under review (WFP, IRC Airbel, DRK Foundation). *We need one person:* *Founding Product Engineer / Systems Architect* You will own the Django backend, MongoDB schemas, and the Flutter UI that connects them. Our AI pipeline lead handles the Gemini orchestration — your job is to own the data layer, build the API surface, and wire it directly into the offline-first client. This is not drawing backend diagrams. You must be an end-to-end builder who cares about how a civilian interacts with the system on the ground in a crisis. A bug in this system isn't a 500 error — it's a missed warning in a conflict zone. Must have: Python/Django, MongoDB, Flutter (or high competence to pick it up fast), and system design thinking. Strong plus: DevOps (Docker, AWS), LLM integration, OSINT, geospatial. We also welcome strong full-stack implementation engineers who ship fast and want founding-team equity. Same stack. *Compensation (No BS):* - Now: Sweat equity (12-18% SA / 5-10% FSD, 4yr vest, 1yr cliff). This is founding-team ownership. - Pre-Seed (closing): $3,000/month + equity. - Seed (6-12 months): 75% market salary + equity. Increases from there. If you need full salary today, this is not for you. If you want to build something where the stakes are real and you're willing to bet on yourself to get there — we should talk. *Stack:* Python 3.9+, Django 4.1.13, MongoDB, Flutter, Vertex AI (Gemini 3 Pro Preview / 2.5 Flash / 3 Flash Preview), Docker, AWS. *Apply:* Email PeterJFrancoIII@gmail.com with subject line `[SENTINEL-BUILDER] - HackerNews Application`.

WireScreen (Series A) | Senior Product Manager | NYC - hybrid | Full-time | $175k-$215k base + equity | https://jobs.ashbyhq.com/wirescreen/3c97417f-45f1-4480-8d38-... WireScreen is a fast-growing Sequoia-backed Series A startup building the go-to open source intelligence platform for navigating global supply chains and China-related risk. While China maintains some of the world’s most detailed corporate ownership records, the real challenge is connecting the dots. That’s where we come in—surfacing the networks, relationships, and financial ties behind companies to support national security, compliance, and regulatory oversight. We’re looking for a Senior Product Manager to join us in an early stage product role that represents an opportunity to define the future of WireScreen’s flagship product. You’ll be part of a small team working directly with company leadership, take full ownership of brand new products, and have a meaningful impact on the future of corporate transparency around the globe. If you have prior startup experience, have worked on at least one data product (or have strong data chops), and bring 6+ years of PM experience - we’d love to talk to you. Apply here: https://jobs.ashbyhq.com/wirescreen/3c97417f-45f1-4480-8d38-... Or you can reach out to me directly with questions or your resume at leo.green@wirescreen.ai - I lead recruiting here at WireScreen, but if I don't know the answer I'll ping our engineering folks and come back to you fast. If you think this role isn’t at the right level for you but are interested in working here, let me know!
