Full-Stack Engineer (AI Platform)

• Agents can already take action inside Thumbtack’s internal systems. The harder problem is making that trustworthy: giving business teams a way to configure what agents are allowed to do, review and correct their work, and see clearly what happened and why. Without that, automation stays stuck in pilots.
• 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
