## About the role

AI agents are beginning to act on behalf of people and businesses against publishers, banks, payment networks, and APIs. Every counterparty today answers identity questions on its own - self-asserted API keys, third-party cookies, pixel trackers. That model breaks the moment the actor is an agent. We're building KYA (Know Your Agent) - a cryptographic identity substrate that replaces self-assertion with third-party-issued credentials, verifiable by any counterparty.

## What they're looking for

- Shipped systems where cryptographic correctness was load-bearing: OAuth/OIDC IdP, token issuer, signing service, HSM-backed signer, passkey/WebAuthn flow, or similar
- Fluent in Python and Go, or strong in one with a track record of learning the other quickly
- Reads RFCs as primary sources and holds informed opinions on JWK thumbprint canonicalization, pairwise-sub derivation, and Signature-Input header serialization
- Deep understanding of the distinction between identity and authorization, mandate and claim, snapshot and live state
- Production experience with async Python on Postgres, including migration safety and observability
