What are the responsibilities and job description for the Founding Engineer - AI Healthtech position at Circle Health AI?
Hybrid – 2-3 Days/Week in NYC HQ🗽
About Us
At Circle Health, we’re on a mission to ensure every mental health and addiction recovery facility can run with zero back-office admin work — freeing clinicians to focus on what truly matters: helping patients heal.
We’re building AI agents that empower healthcare workers — from ASAM-compliant and coded charts at the point of care to real-time auditing records for prior authorization eligibility to ensure clinics get paid faster. Our tools reduce administrative time by 90%, cut documentation delays from weeks to minutes, and are already being used by some of the top SUD, behavioral health agencies, and billing companies in the country.
We’re supported by leading VCs— the same investors who’ve funded some of the fastest-growing AI and healthcare startups. Our team has developed products at Prepared911, Walmart Global, and Bausch Pharmaceuticals, and now we’re bringing that expertise to transform healthcare.
Our DNA
- Obsessed with outcomes. We partner with clinicians, administrators, and compliance teams to solve the right problems — focusing on unmet needs and measurable impact on time saved, claim acceptance, and compliance accuracy.
- Relentless problem-solvers. No blockers, only solutions. We tackle the hardest problems first and find a way through.
- Ship fast, learn faster. We move with urgency, get real-world feedback early, and refine until it’s right.
- Autonomy with camaraderie. High trust, high ownership, and a shared commitment to each other’s success.
- Mission over everything. We’re here to make healthcare better — not just more efficient, but more human.
How We Work
We’re a lean, high-ownership team where every person shapes the product and company. Expect:
- Minimal bureaucracy, high autonomy. We trust you to own your work.
- Direct customer exposure. Engineers have the option to join sales calls, visit clinics and learn first hand of the opportunities to innovate
- Hybrid rhythm. 2-3 days/week in our NYC space to collaborate deeply, experiment rapidly, and build lasting professional relationships.
- Flexible when it matters. Need to ship from home to hit a deadline? No problem. We don’t clock in and out — we solve problems that matter.
What You'll Work On
As a founding engineer, you’ll own features end-to-end — from how data flows through our AI pipelines to how it’s presented in the product. You’ll work closely with leadership and our product-focused founding engineer to bring LLM-powered functionality directly into clinician workflows.
You’ll:
- Design and build LLM-integrated features (prompt pipelines, RAG flows, structured outputs) that run in real time inside the product.
- Connect AI outputs to intuitive frontend and middle-layer experiences for clinicians.
- Develop secure, efficient API layers and integrations with Supabase.
- Implement real-time validation and proactive flagging in chart review and documentation tools.
- Work with customer feedback to refine AI accuracy, reliability, and usability.
- Collaborate on product architecture to ensure scalability, performance, and compliance.
Who We're Looking For
- Strong full-stack skills — comfortable in React/Next.js on the frontend and Node.js/Python on the backend.
- Experience integrating LLMs into production (LLM, LangChain, VectorDB, or similar).
- Understanding of prompt engineering, RAG architecture, and AI-driven UX.
- Comfort working in BaaS environments (Supabase/Postgres or similar).
- Thrives in 0→1 startup environments, happy to ship fast and iterate.
