Full-Stack Engineer, AI Platform

Summary

Thumbtack is a home-care platform that helps people complete repairs, maintenance, and improvement projects. The Full-Stack Engineer will build interfaces and services for an internal AI platform, enabling business teams to configure agents, review and correct their work, and understand agent behavior. The role owns features end to end across frontend, backend, observability, and post-launch improvement.

Responsibilities

• 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

Skills

• 3+ years of professional software engineering experience
• Strong frontend skills with React and TypeScript, including complex application state and data-dense interfaces
• Solid backend engineering ability. We use Go, PHP, and Python, and we expect strong engineers to pick up a new language
• Working knowledge of relational and non-relational data stores (Postgres, DynamoDB, or similar)
• Real product judgment: you can look at a workflow, decide what to build, and say what to cut
• Interest in the problems that come with non-deterministic systems — uncertainty, partial failure, and designing for human correction rather than assuming a correct answer every time
• Proven ability to navigate ambiguity, close your own knowledge gaps, and deliver in an evolving environment
