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 ofFast 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.\nThrough 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.\nFunction 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.\nWe 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.\nRole:\nWe sit on something rare: a fast-growing longitudinal health dataset spanning 50M+ lab tests, 160+ biomarkers per member, advanced imaging, and wearable signals, captured continuously rather than once a year at a checkup.\nYou'll own the agentic system that turns a member's health data into clear next steps, working alongside their clinicians. Day to day, that means building and operating production multi-agent systems end to end: orchestration graphs, tool use and memory, retrieval over a member's records, and the evals and observability to keep it reliable. You'll wire frontier LLMs into Function's proprietary data, and hold the whole thing to the safety, latency, and cost controls healthcare demands.\nThis is a hands-on, high-ownership role for an engineer who has built agents at scale and wants their work measured in healthy years of human life, not just benchmarks.\nImpact You'll Drive:\nPut a concierge doctor in every member's pocket: an agent that reasons over a lifetime of labs, imaging, and wearable signals and tells them what to do next.\nTurn our longitudinal health dataset into decisions, not dashboards, so members act on their health rather than just view it.\nMake health AI that people trust with their lives: every recommendation earns its way past evaluation gates and clinician review before it reaches a member.\nCatch what a once-a-year physical misses, surfacing the early signal across 160+ biomarkers before it becomes a diagnosis.\nKey Responsibilities:\nArchitect and build stateful, graph-based agent workflows with tool use, planning, and memory.\nIntegrate LLMs and multimodal models via structured I/O (JSON Schema, Pydantic validators) and function/tool calling.\nBuild high-reliability APIs and streaming services for real-time inference, speech, and vision.\nOwn production readiness: tracing, logging, metrics, rate limiting, circuit breakers, and SLOs\nStand up eval pipelines: offline golden sets, LLM-as-judge with human rubrics, online A/B, and regression tests in CI.\nImplement retrieval and memory: hybrid search, vector and graph retrieval, semantic caches, and long-horizon context.\nOptimize cost/latency: model routing, prompt and tool selection, quantization, and KV cache/prefill strategies.\nPartner cross-functionally to translate research into robust production systems and iterate quickly behind evaluation gates.\nMentor engineers through design docs and architecture decisions.\nQualifications/Skills:\nTo excel in this role, candidates must bring a unique combination of skills and experiences:\n 1+ years building agentic AI systems; 6+ years as a full-stack or ML engineer, building production backends or ML systems in Python, Go, or similar.\nFluency with agentic orchestration (e.g., LangGraph, PydanticAI, DSPy, LlamaIndex) and tool/function calling.\nExperience integrating frontier LLMs and multimodal models via managed APIs or self-hosted serving.\nStrong with API design and backend frameworks (FastAPI, Flask) and event-driven architectures.\nData systems expertise with PostgreSQL, including token streaming and throughput tuning.\n Retrieval and memory: vector databases (pgvector, Pinecone, Weaviate, Milvus), hybrid search, and graph/knowledge storage.\nProduction evals: LLM-as-judge, human-in-the-loop, rubric design, and CI-integrated regression tests.\nObservability and SRE: OpenTelemetry traces, metrics, structured logs, SLOs, dashboards, and on-call triage.\nCloud-native delivery: Kubernetes, Terraform, Docker, GPU scheduling/autoscaling on AWS or GCP.\nCI/CD proficiency with GitHub Actions and test automation for prompts, tools, and agents.\nClear, concise communication and high ownership in fast-paced environments.\nNice to Haves:\nReal-time multimodal systems: streaming ASR, low-latency TTS, WebRTC, and vision pipelines.\nRAG expertise beyond basics: Graph RAG, multi-hop retrieval, sub-agents, query planning, and freshness policies.\nSafety and governance: policy-as-code, red-teaming, PII handling, audit logs, and role-based tool authorization.\n Regulated data experience (HIPAA, SOC 2, GDPR) and data residency controls.\nPersonalization at inference time, long-term memory agents, session state, and episodic memory stores.\n Experience with consumer-scale AI apps, high-traffic systems, or on-device/edge acceleration (WebGPU).\nTo be a strong fit, you also need:\nRuthless Prioritization:We don’t let perfect get in the way of progress.\nWe move quickly to drive value, not perfection.\nWe prioritize what drives impact.\nWe never compromise on standards of excellence.\n\nMember-First, Always:We design and deliver like we’re caring for someone we love.\nWe create calendar, actionable, human experience.\nWe prioritize responsiveness, peace of mind, and outcomes.\nWe empower members with truth, clarity, and care.\n\nOne Team, Moving Fast:We are aligned in purpose, prioritization, and speed.\nWe gather diverse perspectives to make informed decisions.\nWe clear paths for each other and move fast together.\nWe communicate clearly and respectfully, rallying around shared goals.\n\nRadical Ownership, Relentless Execution:We don’t just ship- we own outcomes and drive results.\nWe act with urgency and precision\nWe anticipate, initiate, and follow through.\nWe meet challenges with grit and pragmatism.\nWe embrace new tech to deliver better outcomes.\n\nMission Over Ego:We are ruthlessly aligned to our mission - and leave ego at the door.\nWe disagree and commit.\nWe don't tolerate politics or withholding information.\nWe operate with honesty, transparency, and respect.\n\nSustained Integrity in Every Detail:We earn trust by obsessing over accuracy, quality, and clarity in everything we do.\nWe prioritize clinical precision - data must be right.\nWe sweat the details because outcomes depend on them.\n\nYour 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.\nWhy You'll Love Working With Us:\nWe value our team at Function and offer a competitive salary and benefits package, flexible working hours, and a dynamic work environment where creativity and innovation are encouraged.
