Senior Software Engineer, AI

Tono Health builds software and operations for specialty care, starting with dermatology. The Senior Software Engineer, AI will build production AI agents for clinical and operational workflows and develop shared agent infrastructure, evaluation systems, and reliability safeguards.

Responsibilities:

• Own the agents that run Tono's clinic end to end. You'll design, build and ship AI agents that handle real clinical and operational work, such as drafting clinical notes, triaging intake, coordinating care, and automating the admin work that slows doctors down. You'll work in our TypeScript monorepo (Cloudflare DO, tRPC, Prisma, Postgres, Inngest) alongside the engineers, physicians and care coordinators who use what you build
• You'll also build the foundation other engineers build on: shared agent infrastructure, tool and memory abstractions, durable workflows, tracing, and the evaluation harnesses that tell us whether an agent is actually getting better
• Building an agent that turns a patient visit into a structured clinical note a doctor trusts
• Designing evals and labeled datasets from real clinician feedback, then using them to catch regressions before they ship
• Building self-improving loops where physician corrections flow back into prompts, retrieval and fine-tuning
• Adding guardrails, human-in-the-loop review and safe fallbacks so an agent fails gracefully
• Debugging why an agent did something unexpected, using traces, logs and replay
