Founding Software Engineer

About Us

Insurance runs on manual work nobody wants to do. Here at Avallon, we're building agentic systems to transform the repetitive, monotonous tasks the insurance agency is faced with daily. We grew revenue 20x in 10 months since Y Combinator, raised from top investors and are scaling fast. Our backgrounds span top institutions like MIT, Harvard, and Cornell, and our work includes published research in NLP.

The Role

We're hiring our Founding Software Engineers to own the foundation on which every agent and product at Avallon is built. We have autonomous voice and worker agents in production replacing thousands of manual tasks everyday, adapting to brand new scenarios, and serving the world's largest insurance carriers.

What You'll Own

The agent execution platform, the core harness powering every agent at Avallon: turn handling, tool orchestration, session lifecycle. You own provider routing, multi-provider failover, cost optimization, latency-aware model selection. You build the eval platform that catches regressions before customers do: per-run evals, canary deployments, automated regression detection. And you own the developer platform that unlocks team velocity with coding agent workflows, internal tooling and CI/CD.

How we build

A forward-deployed engineer sits with a customer on Monday, surfaces a pain, and hands it off to you. By Friday, you’ve specced the solution, assigned a coding agent to build it, reviewed the output, and shipped it. That’s not aspirational, that’s the current cycle. We design systems, write technical specs, and orchestrate AI agents to execute.

You

• Comfortable in a founding role as you shape the platform and the product direction.

• High agency, full ownership. You’re the driver, not a contributor.

• TypeScript, SQL, 4+ years building production software.

• Built reliability infrastructure with retries, circuit breakers, graceful degradation and observability.

• Regulated or security-sensitive environment experience. Every action needs a trail.

• Based in NYC or willing to re-locate.

A few things we believe in

• Eating well: We provide lunch and dinner every workday from local restaurants.

• Staying healthy: 100% of medical, dental, and vision insurance covered, along with a generous monthly gym stipend.

• Getting out of the office together to recharge: quarterly offsites somewhere you actually want to go.

• And our favorite: unlimited token budget. No caps, no rationing, no "can you try a smaller model." Build with whatever makes you fastest.
