About the job
Works directly with enterprise customers to turn their APIs into agent-usable tools, build tool-selection evaluations, and ship production integrations.
What you'll do
- Own enterprise engagements from discovery and specification through implementation, QA, and release.
- Build and maintain custom and composite tools, schemas, scopes, customer SDKs, and per-customer patches.
- Create repeatable toolkit QA and evaluation harnesses, and coordinate customer updates and escalations.
What they ask for
- Production integration engineering experience with enterprise APIs and authentication, including OAuth 2.0, consent models, scope design, and multi-workspace tokens.
- Experience owning a named enterprise account from first call to launch and translating customer needs into specifications.
- Experience building with language models and designing agent-tool interfaces.
- Clear communication, sound architectural judgment, and strong developer-experience instincts.
Nice to have
- Production Python experience; TypeScript is a plus.
- API platform, iPaaS, or integration-heavy background; prior FDE/solutions architect work selling to big tech; or frontier output such as MCP servers, tool-use evals, or agent-tooling writeups.
Tools
