Full-Stack Engineer (AI Platform)

Join Thumbtack, a company dedicated to helping small business owners thrive. As a Full-Stack Engineer, you will design and build interfaces for business teams to configure agents, review their work, and understand their actions. You will work across the stack, from React and TypeScript to service code and data models, and partner directly with business teams to translate operational problems into working software. You will own the full lifecycle of your work, including monitoring and post-launch improvement. Enjoy a virtual-first working model, generous PTO, and a range of benefits.

About Thumbtack

• Solid backend engineering ability. We use Go, PHP, and Python, and we expect strong engineers to pick up a new language
• 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

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

Requirements

3+ years of professional software engineering experience

• 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
• Strong frontend skills with React and TypeScript, including complex application state and data-dense interfaces
• Proven ability to navigate ambiguity, close your own knowledge gaps, and deliver in an evolving environment
