Chestnut | Senior Product Engineer | SF or Seattle (Hybrid) | https://jobs.ashbyhq.com/Chestnut

I'm Nick, CTO & co-founder. We're Rippling, but for insurance carriers paying their sales force. Every policy sold triggers a chain of payouts across brokers, agents, and sub-agents. Today that runs on spreadsheets and legacy vendor systems and tomorrow they'll run on Chestnut. Nationwide and other major carriers have already made the switch.

Revenue is up 8x in the last year. We're backed by a16z. Founding team came out of leadership at Ethos (insuretech that recently IPO'd in January).

The work is state-heavy and correctness-critical: payouts that must reconcile with finance to the cent, dynamic agent hierarchies, retries, chargebacks, partial failures. These systems move real money and cannot drift.

You'll design schemas, build backend logic, ship UI, deploy, and own the sharp edges that show up with real enterprise customers.

Stack: Go, TypeScript/React, Postgres, Temporal, Kubernetes, AWS. We use AI aggressively and expect you to as well.

We're looking for 3–6 years on real product systems. You're thoughtful about invariants and failure modes.

Chestnut | Product Engineers (Backend / Full-Stack) | SF + Seattle (Hybrid) | https://jobs.ashbyhq.com/Chestnut

Chestnut builds the systems insurance carriers actually run their distribution business on. We replace spreadsheets, legacy vendor systems, and manual processes with real-time data, deterministic workflows, and AI-assisted tooling.

This is end-to-end product engineering.

You won’t just write APIs. You’ll design schemas, build backend logic, ship UI, deploy to production, and handle the sharp edges that show up with real customers. The problems are messy and state-heavy: payouts that must reconcile with finance, onboarding flows with regulatory constraints, dynamic hierarchies, retries, chargebacks, partial failures.

We care a lot about correctness. These systems move real money and cannot drift.

Stack: Go, TypeScript/React, Postgres, Temporal, Kubernetes, AWS

We use AI heavily in our workflow — for drafting, refactoring, test generation, and exploring solutions. We expect engineers to use it aggressively. We also expect you to understand what it’s doing, spot when it’s wrong, and maintain strong fundamentals. Taste matters.

You’ll likely thrive here if you: - Have 3–6 years building real product systems - Are strong in at least one typed language and comfortable picking up others - Enjoy owning features end-to-end - Think in terms of invariants, edge cases, and failure modes - Like shipping quickly but cleanly - Want to build systems that operate in production, not demos

We’re a small, high-agency team. You’ll have meaningful ownership and direct impact on customers.

Hybrid in SF and Seattle.

Chestnut | Hiring Senior / Staff Software Engineers | SF + Seattle (Hybrid) | https://jobs.ashbyhq.com/Chestnut

Chestnut builds software insurance carriers actually run their business on. We replace legacy, manual distribution systems with real-time data, automated workflows, and AI-driven tooling in a space that hasn’t changed much in decades.

This is product engineering. We ship to real customers, operate what we build, and spend time fixing the sharp edges that show up in production.

You’d work on backend-heavy product features around onboarding, compliance, payouts, and integrations. A representative problem: building a commission payout flow that ingests messy carrier data, applies complex rules and hierarchies, explains results to ops, and executes payouts that must reconcile cleanly with finance—while handling holds, chargebacks, retries, and partial failures.

Stack: Go, TypeScript/React, Postgres, Temporal, Kubernetes, AWS, LLM tooling.

Roles:

- Senior Software Engineer – Product / Backend (https://jobs.ashbyhq.com/Chestnut/fbbb7601-3d31-48b4-8639-75...)

- Staff Software Engineer – Architecture & Scale (https://jobs.ashbyhq.com/Chestnut/f28c5ee5-12aa-4e7b-b0ea-f5...)

- Engineer – Agent Orchestration & Workflow Systems (https://jobs.ashbyhq.com/Chestnut/075a0010-bfa5-489e-8808-e9...)

I didn't say it was the same codebase. "Inspired" may be more accurate but the point still remains that the concepts in Kubernetes have a direct path to the concepts in Borg.

Thanks for the feedback!

Excel with multiple worksheets is on the roadmap. Wanted to get the leanest solution out first to better gauge interest.

There is a link to a live API on the homepage, and a playground on the API's page which you can use by hitting "Free Token" up top.

The copy and placement of those buttons needs to be cleaned up to be conveyed better.
