Member of Technical Staff

The role

You will build and operate AI and data systems for AI-driven primary care. This generalist role involves working across model training, data pipelines, retrieval, and product workflows.

What you will do

• Build and iterate on AI agent workflows for clinical reasoning and tool use.
• Design guardrails and fallback logic for safe autonomous behavior.
• Prototype and ship AI-powered product features end-to-end.
• Improve knowledge bases, retrieval accuracy, and data lineage tracking.
• Rebuild data pipelines to ensure traceability and support corrections.
• Design models that sync with health data partners and credentialing authorities.
• Build and optimize real-time voice pipelines for patient interactions.
• Develop low-latency, streaming voice agents.
• Fine-tune voice and video models for medical terminology and accessibility.
• Build monitoring and analytics for background jobs and model performance.

Required qualifications

• Strong programming skills, preferably Python
• Experience with system refactors, schema migrations, and data infrastructure simplification
• Familiarity with PostgreSQL (including JSONB and vector types) and AWS
• Experience building production systems that power AI or ML workflows
• Hands-on experience with LLM APIs, prompt engineering, and shipping AI-powered product features
• Comfort working across the stack, from schema design to production debugging

Nice to have

• Familiarity with training infrastructure and frameworks (PyTorch, Hugging Face, vLLM, Axolotl, or similar)
• Experience with RLHF, DPO, or other alignment and preference-tuning techniques
• Experience building or improving AI agent systems with tool use and multi-step reasoning
• Experience building retrieval systems for LLMs (RAG pipelines, vector search, grounding)
• Familiarity with FastAPI, SQLAlchemy, DuckDB, Temporal, ClickHouse, Valkey, or similar systems
• Experience with real-time voice AI systems, speech models, computer vision, medical imaging, or multimodal models
• Knowledge of logging/monitoring stacks (Sentry, Langfuse) and containerized deployments (Docker, ECS)
• Experience simplifying multi-layered data systems
• Strong intuition for designing systems that balance correctness, observability, and performance

Before you apply

• Quick intro call
• Short technical screen
• 1 deeper technical interview + team chat
• References + offer
