Senior Engineer, Agentic Identity

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. We're hiring an engineer to own a meaningful surface of the substrate - issuer mint, edge verification, Passport, or Merkle audit log - and ship it to production.
