Staff Applied AI Engineer

We are looking for a Staff-level Applied AI Engineer with 4-10 years of experience to build the AI foundation of Future's new Health Coach product. We want an optimistic, curious engineer who has shipped LLM agents to production, ideally with a strong big-tech background, who has since moved into startups or founded a company. This is a beta-stage, fast-changing environment, so you'll need to work independently and drive results. Future is backed by a board that includes Tom Brady, Eddie Cue and Adam Bain, and has a CPTO from Function Health. Your work will turn members' biomarkers, DEXA scans and wearable data into personalized guidance that their human coaches can act on.

What will you be doing?

• Building and shipping production AI agents for Health Coach: tool-calling LLM systems with structured output, parallel API orchestration and streaming responses.

• Building AI-driven features such as coach matching and clinical-leaning guidance across sleep, nutrition, fitness and wellness, with a human always in the loop.

• Owning the full loop: prototyping new agent capabilities, validating them with Langfuse evals and rubrics for safety, effectiveness and personalization, then deploying, monitoring traces and iterating.

• Improving reliability, latency and cost through prompt caching, token budgets, retry logic and observability.

• Writing the tools agents use (Pydantic-validated API integrations, data search and structured submissions) and working closely with product, design, mobile and backend engineers in an EPD pod.
