About the role

This role will be operating at the intersection of applied research and engineering, building crucial AI capabilities, and owning their robust implementation. You will have direct impact on shaping the models served in our products, and the user experience as well as business value that is driven by them.

What you'll do

Post-training, distillation and reinforcement learning

Create training environments that elevate the quality ceiling of synthetic data, and provide high-quality reward signals for both off- and on-policy learning.
Design model behaviors that optimize for interpretability and an outstanding user experience.
Train agentic models that autonomously interact with complex structured and unstructured environments, write and prototype code, and navigate multimodal inputs.
Utilize the best tool for the job – SFT over synthetic data, on-policy distillation, RL or any combination of these to drive down the cost of specialized intelligence.
Own benchmarking pipelines – assemble high-quality datasets and measure impact of different training parameters or methodologies.

Engineering Principles

AI engineers are engineers – build production-ready code and own the end-to-end process of data, training, benchmarking and implementationArchitect scalable inference strategies that maximize compute efficiency.
Maintain solutions to ensure stable, reliable execution for customers.
Closely collaborate with engineering team to design important intersections of AI and product services such as interfaces, inference tracking, checkpointing, data persistence and caching.
Contribute to engineering culture; mentor peers, evolve patterns, raise the bar on code quality, testing strategy, and documentation.

Tooling & Resources

Work with bleeding-edge open-weights models and internal training frameworks.
Stay at the forefront of open research and tooling– rapidly prototype and validate novel approaches.
Contribute to internal tooling for inference, training, orchestration, and data generation.

Soft Skills & Mindset

Communicate ideas and explain solutions – even to a non-technical audience.
Autonomously build demonstrations and showcase work to the wider company.
Break down ambiguous problems into a clear technical scope – think beyond immediate business needs and. incorporate future scalability into each design.
Proactively collaborate with team members and seek out all resources relevant to the task at hand.

Qualifications

Our ideal candidate has all of the following:

Strong background in both ML and engineering
Great communication skills and rapid understanding of problem descriptions
High agency; willing to propose, prototype and own solutions
Experience in post-training large models (SFT, distillation, RL)
Experience deploying models at production scale
Previous work with dockerized systems (Docker, Kubernetes, etc.)
Previous contributions to open research or AI infrastructure
Strong familiarity with latest AI research and open-source tooling
Experience shipping complex software and owning production-code

Nice to Have

Experience performance-engineering inference architecture for maximum throughput (vLLM, SGlang, llama.cpp)
Detailed knowledge of RL frameworks (verifiers, ART, prime-rl, trl)
Published models or blog posts/publications

Success Indicators

Benchmarks and user metrics: Model quality does not just exist in a lab – both benchmarks and real user metrics are critical to evaluate model quality.
Reliability: Minimizing hallucinations, maximizing inference uptime and consistency, ensuring high accuracy in expected model outputs.
Interpretability: We do not build black-box AI – all models must be able to communicate reasoning processes, break down code execution, reference sources and achieve consensus decisions.
Impact: Improving internal frameworks and tooling, elevating technical culture, educating teams and sharing learnings.
Collaboration: Ownership of projects without micro-management, agency in seeking out and offering help wherever possible.

Prior experience introducing AI tools for engineering velocity (e.g., Copilot, Cursor, codegen pipelines).
Strong product instincts or prior experience collaborating closely with high-performing product managers—able to ask the right questions, challenge assumptions, and think critically about tradeoffs.
Track record of growing into leadership roles in early-stage companies.
Passion for building solutions that help people manage chronic health conditions using real-time data.

Why This Role Is Exciting

You’ll define and own the technical backbone of a fast-growing health-tech company solving critical real-world problems.
You’ll stay close to code while influencing architecture, delivery processes, and team culture.
You’ll have the opportunity to grow into a Team Lead role as the team scales—this is a foundational hire.
Your work will empower people with metabolic disorders like PCOS, diabetes, NAFLD, and IBS to regain control of their health using data from wearables and AI.
You’ll shape the next generation of AI-enabled developer workflows, boosting productivity through modern tools and smart automation.

What We Offer

Generous PTO: Take the time you need to stay fresh and inspired.
Competitive Compensation: Salary plus benefits to match your experience and dedication.

Quickly get up to speed on new features and tasks coming from other teams

The Team You’ll Join

Our mission is to speed up Time to Market, keep the architecture clean, reduce costs, and lay the foundation for scaling. Any serious backend challenge in the company usually ends up on our plate.
