- This engineer owns the product surface that turns agent capability into something teams will actually rely on for business-critical work — and the services behind it

- Design and build the interfaces business teams use to configure agents, review their work, approve or correct actions, and understand what happened and why

- Build observability and evaluation tooling that makes agent behavior legible — where it succeeded, where it failed, and whether a change made things better

- Work across the stack, from React and TypeScript through service code and data models, owning features end to end through build, test, launch, and iteration

- Partner directly with the business teams who use what you build; translate ambiguous operational problems into working software

- Own the full lifecycle of your work, including monitoring and post-launch improvement
