Just-in-time tool calls, secure delegated auth, sandboxed environments, and parallel execution across 1,500+ apps. Backed by Lightspeed.
About the role
• own enterprise accounts end to end: discovery, spec, implementation, QA, release. • ship production code in our toolkit monorepo and customer SDKs: custom and composite tools, schema and scope changes, per-customer patches.
What they're looking for
- if you are very good, nothing is a must per-se
- • applied integration engineering
- – you ship production code, not demos
- – you live in enterprise APIs and auth: OAuth 2.0, consent models, scope design, multi workspace tokens. you know the edge cases from scars

• turning an 800-endpoint enterprise API into a tool surface a model can navigate. tool granularity, composite tools, description engineering, scope design. no textbook exists; you write it in production.
• building the evals that tell us an agent picked the right tool. the field has no good answer; your harnesses become ours.
• working directly with the engineers defining...
