About Us

Function Health is the AI operating system for health, designed to empower people to live 100 healthy years. Through advanced diagnostics, deep biomarker testing, longitudinal data, and AI-enabled insights, Function equips hundreds of thousands of members with the intelligence to take control of both the quality and length of their lives. Function has been recognized as one of Fast Company's Most Innovative Companies of 2024 and is venture-backed by Andreessen Horowitz (a16z),with a recently announced $298M Series B.

Function's Imaging Team powers one of the most advanced cancer screening platforms in the world, offering AI-driven MRI scans across 13 organs at 180+ imaging facilities in 150+ cities across the US and abroad. This infrastructure sits at the core of Function's mission to move healthcare from reactive to proactive, and is scaling rapidly as part of the company's next chapter of growth.

We are building a world-class team that believes deeply in that mission, operates with a relentless bias toward action, and brings the technical rigor to match the ambition.

Role

As a Senior Full Stack Developer on the imaging team, you will be a technical leader who architects, builds, and scales the web platforms that power our cancer‑screening experience. You’ll mentor engineers, drive best practices, and ensure that our .NET‑based backend and modern Vue frontend work seamlessly together to deliver reliable, secure, and delightful products that save lives.

We are seeking a collaborative and detail-oriented developer who thrives in a supportive and mission-driven environment. Must have a problem-solving mindset, excellent communication skills, and the ability to clearly articulate technical concepts. This position will align well if you enjoy working as part of a team, have a human-centered approach to technology, and are passionate about the positive impact your work can have on people's health.

Our technical interview process is language agnostic.

Key Responsibilities

Join a passionate and collaborative team dedicated to groundbreaking health solutions.
Deliver full‑stack solutions, from crafting customer-facing UIs to optimizing database queries and owning the interactions between all layers.
Lead design and delivery of end‑to‑end features across the stack, with an emphasis on high‑performance ASP.NET Core services.
Architect clean, maintainable, and secure APIs that integrate with EMRs, imaging partners, and AI services.
Mentor & coach other engineers through code reviews, pair programming, and design sessions.
Collaborate closely with product, design, and clinical teams to translate requirements into intuitive desktop, tablet, and mobile experiences.
Own quality and define automated test strategies (unit, integration, e2e) and champion CI/CD and DevOps in Azure.
Drive continuous improvement by introducing best‑in‑class engineering practices, performance tuning, and observability.
Shape technical roadmap and contribute to development planning, daily stand‑ups, and retrospectives in our Agile process.

Qualifications/Skills

Bachelor’s degree in Computer Science, Software Engineering, or a related field.
Full-stack experience with demonstrated ownership of both modern frontend and backend in production.
Experience designing microservices, RESTful APIs, and event‑driven systems; shaping data models and domain boundaries.
Deploying and operating workloads in Azure (or AWS/GCP) using IaC, containerization (Docker/Kubernetes), pipelines, and monitoring.
Deep experience with SQL Server.
Proficiency in implementing automated testing with xUnit/NUnit/Jest/Playwright and enforcing clean code standards.
Proven track record of mentoring engineers, leading projects, and influencing engineering strategy.
Excellent written & verbal communication and a bias for collaboration in a cross‑functional, Agile environment.

Nice-to-Have Skills And Experiences

While the core competencies are essential, the following qualifications will distinguish exceptional candidates:

Experience with DICOM, HL7/FHIR, or other healthcare standards.
Background in security & compliance (HIPAA, SOC 2).
Passion for responsive design, PWAs, and accessibility.
Experience with Python, GCP & FastAPI a plus for future initiatives.

Why You'll Love Working With Us

As a Senior Full Stack Developer, you'll have the opportunity to make meaningful contributions within a fast-growing organization committed to early cancer detection. You’ll also have access to:

Stock options.
Comprehensive health, dental, and vision plans for you and your family.
Flexible work environment.
