- Propose and implement authentication and authorization protocols for agent applications.
- Build event forwarding with inbound signature verification and project-scoped outbound identity routed to the correct deployment and environment.
- Extend SDKs, consent-redirect flows, and framework adapters to simplify agent credential access.

- Strong TypeScript skills and comfort developing backend and frontend components.
- Experience integrating with many third-party APIs, including undocumented behavior, non-compliant OAuth implementations, and inconsistent errors.
- Ability to work through ambiguity, ship incrementally across a broad platform surface, and communicate clearly with teams building on the platform.
- Experience or interest in using agents and AI in development workflows.
- Preferred experience operating an OAuth authorization server, identity provider, or multi-tenant integrations platform.
- Preferred experience with MCP, agent tool-calling, delegated access, consent patterns, integration marketplaces, partner engineering, or webhook infrastructure at scale.
- Open-source contributions in authentication, Next.js, or agent tooling ecosystems are a bonus.
