About the Role

You will build internal products and agents across the stack, from data model to UI, for workflows teams depend on. You will put Claude to work on real tasks, make agents safe with guardrails, evals and audit trails, build shared APIs and MCP tools, integrate third-party systems, lead technical direction and operate what you ship.

  • Experience leading design and delivery of complex user-facing products

  • Experience working closely with non-engineering partners
  • Bachelor's degree or equivalent experience

Responsibilities

  • Design and ship internal products end to end from data model to UI
  • Put Claude to work on real tasks and decide where agents versus UI fit
  • Make agents safe with scoped access, guardrails, evals, audit trails and confirmations
  • Build shared capabilities exposed as APIs and MCP tools
  • Treat speed and polish as product requirements and work with users
  • Build for correctness, idempotency and reconciliation
  • Integrate with third-party systems
  • Set technical direction, lead engineers and mentor through reviews
  • Operate and be on call for what you ship
