AI Fullstack Engineer, Health Intelligence

About the role

The Health Intelligence team is at the forefront of integrating modern AI and LLMs into the Oura experience, transforming how members interact with and learn from their data. We are building the next generation of AI-powered health guidance at Oura, blending traditional ML with modern LLMs, reasoning systems, and robust evaluation - not as "chatbots with vibes," but as rigorously evaluated components that explain decisions, surface trade-offs, and adapt member journeys over months and years. As a Senior AI Engineer, you will design, build, and operate the systems that make this possible: LLM-backed workflows, retrieval and knowledge representations, evaluation pipelines, personalization logic, and the full stack product surfaces that together power Advisor, Adaptive Insights, notifications, and future navigation features. You'll: Work with rich longitudinal signals from wearables plus real-world context. Help turn ambiguous health questions into structured, testable AI systems. Balance scientific depth, engineering pragmatism, and product impact so millions of members get guidance that respects both their biology and their real lives. This role is ideal for someone who wants to work end-to-end - from problem framing and model/tooling choices to productionization, evaluation, and iteration - across both product-facing experiences and backend systems, in a domain where outcomes and behavior change, not clicks, are the primary success metrics.

Responsibilities

• You don't need to do all of these on day one, but these are the kinds of problems you'll own:
• Contribute to a multi-LLM and reasoning platform: Prototype and productionize workflows across multiple model providers and configurations, including routing logic and shadow-mode experimentation. Collaborate with infrastructure and science teams on reasoning, planning, and multimodal use cases.
• Partner cross-functionally: Work closely with product, data science, research, design, and content to shape problem definitions, constraints, and evaluation plans. Communicate trade-offs clearly and help the team make principled decisions in a fast-moving domain.

Requirements

• We'd love to hear from you if you have:
• 2+ years of hands-on experience in AI engineering, with a multi-year background in backend engineering, full stack product engineering, applied ML, or related roles building production systems.
• Strong proficiency building production systems across the stack, including user-facing product surfaces and backend services, and comfort working
