## About the role

We’re looking for a strong engineer to help build the identity provider, approval systems, and control plane for agent auth. This is a high-leverage role at the boundary of protocol design, security, and product implementation. You’ll work on the trust model behind agent authorization: signed grants, offline verification, request signing, approval flows, delegation, revocation, and least-privilege capability systems. You’ll help turn emerging protocol decisions into real issuer, approval, and platform systems.

## What they're looking for

- Experience level — 7+ years building production systems in security-sensitive or protocol-heavy domains
- Security-sensitive systems — strong experience building systems where correctness, trust, and misuse resistance matter
- Token and key systems — hands-on experience with signed token formats, key lifecycle, and binding tokens to specific requests in real systems
- Secure-by-default product judgment — strong instincts for making secure behavior the easy default, and for knowing when ergonomics and security are genuinely in tension versus when thoughtful design can deliver both
- Systems implementation — strong TypeScript and backend engineering ability, with comfort building production libraries, APIs, control planes, and developer-facing tooling
- Collaboration and ownership — low ego, high conviction, and the ability to work across protocol, product, and engineering details without waiting for perfect specs
