Founding Engineering Lead @ Behavioral Health Startup

Role

Founding Engineering Lead – Full-Stack with LLM

San Francisco

Our client is building a new behavioral health workflow automation platform that eliminates administrative burden in mental health clinics. They have found a white space in behavioral health testing (ADHD, autism, concussion clinics) where there's minimal existing technology and high openness to new solutions. As a result, they've achieved early product-market fit working with top institutions such as Harvard and large well-known clinics throughout the United States.

As a Founding Engineering Lead, you’ll work closely with the existing team to make prototype code reliable and scalable. You'll own two products end to end, executing on a roadmap that has been validated by the market. This role is ideal for a high agency, scrappy engineer who wants to be part of a company with clear product market‑fit doing something impactful.

• Own the product end-to-end: Help architect and implement the core experience using Type Script, React, Next.js, and Supabase/Postgres.
• Reliability and scale: Make existing prototype code both reliable and scalable.
• Data Pipeline: Create systems that ingest a large amount of data, augment as needed, and apply AI rules around what's missed when needed.
• AI infrastructure: Create systems that process large volumes of data (including voice).
• Develop lightweight memory/state systems: Build ways to track user sentiment, patterns, and emotional state across sessions.
• Execute quickly, ship with care: Build MVPs and features that feel thoughtful and intentional — fast, but not sloppy.

• 3–6+ years of full-stack experience (ideally React/Type Script)
• Experience with LLM tools (e.g., OpenAI, Lang Chain, vector databases)
• Interest in mental health, journaling, inner work, or emotional design
• Bonus: background in NLP, affective computing, or human-computer interaction

• $150-250k, co-founder level equity for the right person
