Company Overview:
Function Health is the AI operating system for health, designed to empower people to live 100 healthy years. We are redefining how individuals understand, measure, and improve their health by moving beyond the limitations of traditional care and enabling comprehensive, continuous insight into human biology. Function has been recognized as one of Fast Company’s Most Innovative Companies of 2024, and is venture-backed by Redpoint and other leading venture firms. Over half a million members have joined Function to take control of their health.
Through comprehensive lab testing, MRI and CT imaging, longitudinal data, and guidance from AI and clinical teams, Function gives members a complete and continuous view of their health — and the clarity to act on it. Through acquisitions across imaging, mobile phlebotomy, and supplement tracking and optimization, Function is building an integrated health platform that spans the full path from testing to health clarity to daily action.
Function recently announced a $298M Series B and is entering its next chapter of growth. As we scale, the quality and durability of our People systems, data, and insights will directly shape our ability to attract, retain, and support exceptional talent.
We are growing our team and seeking out world-class talent that deeply believes in our mission to positively impact global health, has a relentless bias toward action, and a growth mindset. Function fosters a collaborative and dynamic environment where every day we build the future.
Role:
Function Health is looking for a hands-on engineering leader to build the testing and automation systems that help us release software with confidence. You will set technical direction and build practical systems that verify product behavior, identify regressions, and use AI to reduce repetitive testing work. You will combine conventional test infrastructure with AI-assisted approaches where they improve reliability and efficiency, supported by independently verifiable evidence and clear human oversight.
Key Responsibilities:
- Define the testing and automation roadmap with Engineering and Product, starting with priority workflows and release risks.
- Build reusable test infrastructure, repeatable environments, test data, and CI/CD integration across the agreed product surfaces.
- Develop AI-assisted test creation, exploration, maintenance, and failure investigation; evaluate computer-use agents where they fit.
- Establish meaningful assertions, reproducible failure evidence, and release criteria that independently check agent output.
- Measure escaped defects, flaky tests, verification time, false alarms, and maintenance effort; help teams adopt the system through implementation, documentation, and coaching.
Qualifications/Skills:
- Strong software engineering and hands-on ownership of automation, quality infrastructure, developer tooling, or comparable systems.
- Experience making verification reliable in a delivery pipeline and debugging failures across code, data, and infrastructure.
- Practical experience building with LLMs or agents and evaluating their outputs.
- Technical leadership across teams, with clear judgment about quality, delivery, and adoption tradeoffs.
- Experience with browser or computer-use agents, Playwright or similar automation, AI evaluation, and sensitive-data products.
To be a strong fit, you also need:
- Ruthless Prioritization:
- We don’t let perfect get in the way of progress.
- We move quickly to drive value, not perfection.
- We prioritize what drives impact.
- We never compromise on standards of excellence.
- Member-First, Always:
- We design and deliver like we’re caring for someone we love.

- We gather diverse perspectives to make informed decisions.
- We clear paths for each other and move fast together.
- We communicate clearly and respectfully, rallying around shared goals.
- Radical Ownership, Relentless Execution:
- We don’t just ship– we own outcomes and drive results.
- We act with urgency and precision
- We anticipate, initiate, and follow through.
- We meet challenges with grit and pragmatism.
- We embrace new tech to deliver better outcomes.
- Mission Over Ego:
- We are ruthlessly aligned to our mission - and leave ego at the door.
- We disagree and commit.
- We don't tolerate politics or withholding information.
- We operate with honesty, transparency, and respect.
- Sustained Integrity in Every Detail:
- We earn trust by obsessing over accuracy, quality, and clarity in everything we do.
- We prioritize clinical precision - data must be right.
- We sweat the details because outcomes depend on them.
Your dedication to these responsibilities will directly contribute to the success of our platform and the satisfaction of our users. We are looking for a proactive, skilled, and forward-thinking individual to join our team and help shape the future of our services.
