Oaktree Capital | Senior Software Engineer | Los Angeles, CA (HYBRID) / Hyderabad, India | 1 LA + 2 Hyderabad I'm Julien — I lead Product Engineering at Oaktree. My background is tech, not finance: startups, Meta, data infrastructure companies. I'm hands-on and building a flat, small team that operates like an engineering org, not a bank IT department. If you come from a tech background, this post is for you. We're building the next-generation platform for Oaktree's credit business (private credit included) — one of the largest and most complex investment strategies at a firm managing $220B+ in assets.

In the past month alone we've stood up a new CI/CD system, evolved the architecture, and gone from release cycles measured in months to hours. We're shipping rapidly and the pace is accelerating. The work: data-intensive applications across the full stack of a credit investment platform — ingestion, transformation, analytics, and the tools that put insights into the hands of investment professionals. No traditional PMs — you work directly with business stakeholders, own priorities, and ship. This is a hands-on, code-every-day role. What we're looking for: - 10+ years building and owning data-intensive systems in production -Strong CS fundamentals (data structures, distributed systems, concurrency, performance) - Deep expertise in data modeling, pipeline architecture, and systems that process/transform/serve large volumes of data - Python + at least one statically typed/compiled language (C#/.NET, C++, Java, Scala, Go) - Cloud-native experience (our environment is Azure, but what matters is you've operated at scale) - Comfortable with ambiguity, direct stakeholder engagement, and owning outcomes end-to-end - Genuine interest in applying generative AI practically across engineering and product workflows A note on title: the internal title is Vice President, which is standard in finance. In substance this is a Senior/Staff Engineer IC role. Locations: 1 role in Los Angeles (hybrid Tue-Thu, DTLA office) a 2 roles in Hyderabad, India. Interview process: 0. recruiter screen 1. Behavioral + coding (30 min each, can be split or combined) 2. Onsite: system design take-home + panel, stakeholder meeting, hiring manager please email me jubrown@oaktreecapital.com

We're in the middle of a meaningful migration and platform buildout — you'd be joining at a point where architectural decisions matter and your fingerprints will be on the system for years. *The work:* Our stack is Django + Python on the backend, dbt for data transformation, React/Next.js on web, and Expo/React Native for mobile. We run on AWS and Azure. Right now we're migrating legacy services while simultaneously shipping new features — so you'll need to be comfortable holding both in your head. *What we're looking for:* - Strong Python/Django chops — you've built and maintained production APIs, not just tutorials - Comfortable with React/Next.js; bonus if you've touched Expo or React Native - You understand what a data pipeline actually does (dbt experience a plus, but SQL fluency matters more) - Cloud experience on AWS or Azure — not ops, but enough to not be blocked - You care about code quality without being precious about it *What this isn't:* This isn't a greenfield startup with infinite runway.

AxisCare | Senior + Mid-Level Software Engineers | Remote (US/Canada, ET/CT/MT) | https://axiscare.com/careers

AxisCare | Senior + Mid-Level Software Engineers | Remote (US/Canada, ET/CT/MT) | https://axiscare.com/careers We build the market-leading SaaS platform for the home care industry: scheduling, billing, payroll, CRM, and clinical documentation for agencies across all 50 US states and 6 countries. ~10,000 baby boomers turn 65 every day; the agencies using our software help them stay in their homes. 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). The cover letter matters; we read it first. Tell us what you've built, how AI has changed the way you work with specific examples, and why this team at this moment. Candidates only, no recruiters. Feel free to reach out directly via email to wademeredith [at] axis care [dot] com if you have questions. Apply through the website.

Kinelo | kinelo.com | San Francisco | Onsite (with a bit of flexibility)

Kinelo | kinelo.com | San Francisco | Onsite (with a bit of flexibility) Kinelo solves "context myopia": autonomous and semi-autonomous AI agents don't know what they don't know, so they can't search or find the background information required to accomplish tasks accurately and effectively. The result looks like slop but it's not due to model performance, more due to workflow integration. From there, we're rapidly moving into organizing humans together with autonomous "AI coworkers" into workflows that span both. Our goal is to change how organizations are run and structured. We're hiring for two roles right now: - Product Engineer (https://job-boards.greenhouse.io/kinelo/jobs/4205846009) -- do you have the software engineering wisdom not yet encoded in an LLM? and do you have product sense and the willingness and desire to think several steps ahead in the market? - Founding GTM Lead (https://job-boards.greenhouse.io/kinelo/jobs/4215784009) -- there's no playbook for go-to-market in the category we're creating + the landscape is changing daily. Come architect a strategy and then move mountains to execute on it and help us grow insanely fast. Competitive salary, meaningful (~first batch of hires) equity, founder previously exited to Apple, strong fundraising history (~$10m). Please email us at jobs@kinelo.com. If you want to stand out: - For the product engineer role, tell us how you think the job of a software engineer is changing. - For the GTM role, tell us about a time you got massive results with limited resources, all through your ingenuity, creativity, and hard work.

MiLaboratories | Senior Software Engineer (Biologic Discovery) | Bilbao, Spain | ONSITE | VISA | RELOCATION

MiLaboratories | Senior Software Engineer (Biologic Discovery) | Bilbao, Spain | ONSITE | VISA | RELOCATION MiXCR is the standard for immune analysis, cited in thousands of papers. Platforma is the OS on top — bioinformatics as self-serve, interoperable "blocks" for biologic discovery. 5 of the top 10 pharma (Moderna, Pfizer, others) run discovery with Platforma today. Goal: 10 of 10 by year-end. Hiring 4–5 engineers in 90 days. Our tools are in the methods of approved cancer immunotherapies and COVID vaccines reaching millions. The next paper citing us could be the next drug. We merged frontend, bioinformatics, and data into one team. AI killed the silo wall. Bioinformaticians who leaned into engineering and engineers who leaned into biology now ship at multiples. WHAT YOU'D BUILD - Discovery pipelines: raw sequences → pre-IND leads. Antibodies, biomarkers, workflows real scientists use. - The SDK for comp scientists: TypeScript, Tengo (a Lua-like workflow DSL — yes, you'll learn it), Rust. - The data layer: thousands of formats reduced to one. PFrames, Parquet, DataFusion, lazy columnar everything. WHAT WE'RE LOOKING FOR - Strong TS in 100k-line monorepos (pnpm, Turbo). Polars > pandas. Node ≥22. - Bioinformatics exposure or appetite to learn it month one. We can teach VDJ recombination; not curiosity. - Tolerance for sparse docs and niche DSLs. "Fix the SDK, don't work around it." OFFER - €90–120k base, real ESOP, ARR-tied bonus — when we grow, you grow, in cash, this year. - Bizkaia Special Impatriate Regime: ~15–20% effective tax. Beats London / Berlin / Amsterdam net. - Visa, relocation, soft-landing. No HR, no take-homes. Direct line to engineering. - Bilbao: ocean, mountains, Michelin, low cost of living, highest quality of life. Onsite — context-sharing needs same room. Email: stanp@milaboratories.com (CEO). Subject "HN", include GitHub. I reply personally. Tell me about a scientific CLI you wrapped, a plugin SDK you built, or a Polars query that survived 50M rows.

Y Combinator | Product Engineers on YC's own team | San Francisco | Full Time | $185K-$485K

Y Combinator | Product Engineers on YC's own team | San Francisco | Full Time | $185K-$485K I'm Ryan, an EM and engineer here at YC. We have a small, 18-person software team with no PMs -- engineers own everything end-to-end. We build the software behind YC's $6B in investments: tools that help partners evaluate thousands of startups per batch, AI-powered apps that founders use every day, and platforms like Work at a Startup that connect candidates with YC companies. Engineers get unlimited AI tokens -- both for development and to build AI-powered products. What wouldn't you build to help founders + YC with that much firepower? What makes this different from other roles: * You'd learn more about startups here than you could possibly imagine. Every batch brings hundreds of founders building things across every industry, and you're right in the middle of it. * We attend Demo Day, founder dinners, and work directly with partners and many of the companies. (They make great products!) * We pay well, offer carry in the fund (like equity), and provide generous relocation support if you're not in SF yet. Two roles open: * Product Engineer -- full-stack, own the product lifecycle. Rails/React stack. Build tools that power how YC invests in and supports startups. It's a wide range, and sometimes it feels like labs-like work, other times it feels like a supersuit to power founders and our Partners like Garry and Jared. * Community Builder and Software Engineer -- hybrid role. Run YC's talent-facing programs (meetups, tech talks, career expos) AND build the software that makes them scale. You need to be a great engineer and LOVE to build and support communities. Checkout more about the roles, and email me directly if you're excited to learn more about startups than you will anywhere else - ryan@ycombinator.com https://www.ycombinator.com/careers

Formical | Software Engineer | ONSITE (Hybrid - Delft, Netherlands) | Full-time | https://careers.formical.bio

Formical | Software Engineer | ONSITE (Hybrid - Delft, Netherlands) | Full-time | https://careers.formical.bio At Formical, we believe we can become the first sustainable generation on Earth. Biotechnology plays a key role in this future - benefiting all people, animals, and our planet by making industrial production more sustainable. But bioprocessing still runs on fragmented data and tacit knowledge. The infrastructure to turn data into the intelligence that teams need to scale doesn't exist yet, hindering the sector’s progress. Our product accelerates bioprocessing by connecting fragmented data, enabling predictive modeling, and ultimately closing the loop between measurement and action. We're not looking for specific skills, just willingness to learn. I joined a couple months ago with little React/TypeScript full-stack experience, but with CC I managed quite well coming from a Python backend background. Nothing's enforced though! We're a small team, have some customers, and are looking to build out the platform and the client-base significantly this year. Apply via the link above!

TechTalk | Principal Software Engineer, Agentic Engineering | Vienna, Austria | ONSITE/HYBRID | Full-time

TechTalk | Principal Software Engineer, Agentic Engineering | Vienna, Austria | ONSITE/HYBRID | Full-time For those who know what they're doing - even without AI. Our focus is agentic engineering: building and improving systems, workflows, and engineering practices around AI agents and AI-assisted development. We use AI tools heavily, but we expect engineers to know when they help, when they hurt, and how to keep generated code out of the debt spiral. This is a hands-on role for someone who cares about maintainability, testing, refactoring, deployment safety, and engineering judgment under pressure. You should be able to improve systems yourself, help other engineers work effectively with AI, and raise the bar across teams. You’ll likely fit if DORA metrics are useful to you, not decorative; if you know why small commits matter; if you’ve seen what a good deployment pipeline does to a team; and if you can use AI to scale quality, not just output. Apply at jobs@techtalk.at. No cover letter. Instead, tell us about a system you improved with AI, and what your contribution actually was.

We do full-scale web crawls. We download and perform static analysis on the entire universe of Android APKs and iOS IPAs that are published. Unlike a typical startup where you'll spend half of your time in meetings, and the other half fixing bugs from Jira tickets— at MixRank you'll get to challenge yourself with difficult technical problems that will help you to grow as an individual. We're hiring continuously for the positions below— they aren't singular positions that will close once filled. Our philosophy on hiring is that the candidate is more important than the position.

Always Further, founded by team who created https://sigstore.dev , used to secure npm, pypi, brew, and provide attestations for github releases, nvidia and google for AI model signing - we and are now building https://nono.sh agent security tooling. We have roles open for a principal software engineer: We're looking for a Principal Software Engineer to join as a founding engineer. You'll work directly with the founders to build the core of our agent security runtime. This is a high-autonomy role - you'll shape architecture, engage with early customers, and make the trade-offs that define the product. You will build the layer between agentic reasoning and system execution — intercepting, classifying, and validating every agent intent against security policy before it runs. Design systems that capture and cryptographically verify every instruction and action, maintaining ground truth in environments prone to hallucination and injection. Architect fine-grained, time-scoped primitives that allow least-privilege permissions, with the ability to escalate under controlled, auditable conditions. Work with research to stress-test our security primitives at scale. Turn emerging threat vectors (prompt injection, tool misuse, privilege escalation) into adaptive defences. https://www.alwaysfurther.ai/careers/principal-swe Staff solutions engineer: We're looking for a Solutions Engineer join as a founding engineer and to sit at the intersection of our open source community and our growing base of enterprise design partners. You'll spend your time contributing to Nono, helping shape its architecture, and working directly with customers who are integrating it into proof-of-concept and pilot programmes. This is a hands-on role - early on you'll be deep in the code, reviewing pull requests, triaging issues, and experimenting with deployment architectures, all while being a trusted technical voice for both community members and enterprise stakeholders. Over time, the role will evolve toward solutions architecture and customer-facing engagement, as you build the domain expertise and relationships that make you the go-to person for designing how Nono fits into complex enterprise environments. What You'll Do" Contribute directly to the Nono open source project - code, documentation, and architectural proposals. Experiment with different deployment architectures for Nono across cloud environments, on-premise infrastructure, and hybrid setups and share your findings with others at Always Further, and often with the community, via our blogging platforms or YouTube channel. Work closely with early design partners to integrate Nono into proof-of-concept and pilot programmes, gathering feedback and translating it into engineering priorities. Produce technical content - blog posts, architecture guides, demos.

Kinelo | kinelo.com | Product Engineering (Backend+AI focus) | San Francisco | Onsite (with flexibility)

Kinelo | kinelo.com | Product Engineering (Backend+AI focus) | San Francisco | Onsite (with flexibility) We are hiring two Product Engineers to join us in our newly opened office in SF. We're small and early and you'll help shape team culture. Kinelo solves "context myopia": autonomous and semi-autonomous AI agents don't know what they don't know, so they can't search or find the background information required to accomplish tasks accurately and effectively. The result looks like slop but it's not due to model performance, more due to workflow integration. From there, we're rapidly moving into organizing humans together with autonomous "AI coworkers" into workflows that span both. Our goal is to change how organizations are run and structured. Our #1 hiring criteria for this position is immense software wisdom, the kind not yet encoded in the weights of an LLM. We are not looking for artisans to meticulously craft single lines of code. We're looking for software engineers excited to use the leverage that AI offers for code production to permit focus on higher order technical architecture, product requirements, and user needs. We're looking for enough experience that indicates accumulated wisdom in shipping and maintaining reliable, scalable software, solid CS fundamentals, experience taking products from 0 to 1, and versatility. Our current tech stack includes TypeScript, a managed container service, Postgres, and Redis. But we are adaptive and you should be too. We highly value software engineering and computer science fundamentals and experience with other languages like Go, C++, Python is valued. Competitive salary, meaningful (~first batch of hires) equity, founder previously exited to Apple, strong fundraising history (~$10m). Please email us at jobs@kinelo.com. If you want to stand out, tell us how you think the job of a software engineer is changing. There's also a full JD here: https://job-boards.greenhouse.io/kinelo/jobs/4205846009

Automatically analyse data quality, automatically fix and enhance data, and prevent bad data. Our platform automatically detects issues in master and transactional data, generates improvement suggestions using AI and human expertise, and prevents problems at the source — across systems like Snowflake, Databricks, SAP, and more. *The problem we're solving*: Bad data costs businesses millions. Rules get written manually, issues get caught too late, and fixes are slow. We're replacing that with agentic AI that generates data quality rules, finds anomalies, and drives corrections (!) yes, it automatically fixes the broken data — with humans in the loop where it matters. Our customers across industrial goods, energy, automotive, and healthcare are already seeing real results. *About us*: DQC is a Munich-based AI startup founded in 2022. We're a small (15 ppl), fast-moving team where engineers have real ownership and direct impact on product direction and technical architecture. Short decision paths, no bureaucracy, steep learning curves. *The role*: As a Senior Backend Engineer, you'll own the full lifecycle of feature development — from architecture and design to production deployment. You'll work cross-functionally with backend, frontend, and product to ship features that thousands of users rely on. Our platform sits at the intersection of backend systems, modern data stacks, and LLM-driven workflows, so you'll be building at the frontier of what's possible with AI in production. We practice agentic coding daily and our tech interview includes a live agentic-coding exercise — we want engineers who embrace these tools with judgment, not hype. If you want real ownership, direct product impact, and the chance to build at the intersection of backend engineering and AI — let's talk.
