About the role
We are looking for a Founding Software Engineer with 4+ years of experience to take true end-to-end ownership of the core platform powering Avallon's AI agents — the infrastructure that's already live with top-10 insurance carriers and scaling at 25x revenue growth. This is a high-agency, zero-hand-holding role at a 6-person YC-backed team where you design systems, orchestrate AI agents, and ship production code on a weekly cycle.
What will you be doing?
- Own entire platform components end-to-end — from evaluation pipelines and model reliability to document parsing and agent execution infrastructure.
- Build and maintain reliability systems: retries, circuit breakers, failover, observability, and canary deployments.
- Design and ship the eval platform that catches regressions before customers do, including per-run evals and automated regression detection.
- Collaborate closely with forward-deployed engineers to rapidly spec, build, and ship solutions surfaced directly from customer pain points.
- Shape developer platform tooling, CI/CD workflows, and coding agent integrations to unlock team velocity.
Key Requirements
- TypeScript and SQL as primary production languages — must be clearly evidenced on resume or GitHub.
- Hands-on AWS experience in a production environment.
- Startup experience (Seed–Series B) with demonstrated end-to-end ownership of a core platform component — not just feature contributions.
- Experience in a regulated or security-sensitive environment (fintech, insurtech, healthtech) where auditability and traceability were hard requirements.
- A public artifact (GitHub, personal site, publication) showing genuine engineering interest outside of day-to-day employment.
