About this role

## About Thumbtack Thumbtack helps millions of people confidently care for their homes—connecting homeowners with the right projects, timing, and local service businesses. ## Business Applications Team The Business Applications org builds and operates the internal systems that keep Thumbtack running at scale (e.g., Salesforce-centered workflows, admin tooling, and cross-team integrations). They’re expanding this foundation into a broader internal platform for **AI-enabled work**, including shared APIs, reusable integration patterns, and **safe, auditable** capabilities for business-critical actions. ## The Challenge Agents can already take action inside Thumbtack’s internal systems. The harder problem is making automation **trustworthy** for business teams—by enabling configuration of what agents are allowed to do, review/correction of agent work, and clear visibility into what happened and why. ## Role: Full-Stack Engineer, AI Platform You’ll own the product surface that turns agent capability into something business teams can rely on for business-critical work—along with the services behind it. ### What you’ll do - Design and build the interfaces business teams use to: - configure agents - review their work - approve or correct actions - understand what happened and why - Build observability and evaluation tooling to make agent behavior legible (successes, failures, and impact of changes) - Work across the stack end-to-end (React + TypeScript through service code and data models), owning features from build → test → launch → iteration - Partner directly with business teams; translate ambiguous operational needs into working software - Own the full lifecycle of your work, including monitoring and post-launch improvements ### Requirements - **3+ years** of professional software engineering experience - Strong frontend skills with **React** and **TypeScript**, including complex state and data-dense interfaces - Solid backend engineering ability (they use **Go, PHP, and Python**; expect to pick up new languages) - Working knowledge of relational and non-relational data stores (e.g., **Postgres, DynamoDB**) - Strong product judgment (know what to build and what to cut) - Interest in non-deterministic systems (uncertainty, partial failure, designing for human correction) - Ability to navigate ambiguity, close knowledge gaps, and deliver in an evolving environment ## Compensation (Expected Total Cash) - **San Francisco / Bay Area, San Jose, NYC, Seattle metros:** $177,700.00 – $229,900.00 - **Austin, TX / Washington DC metros** and **CA, MA, NJ, WA states:** $159,800.00 – $206,800.00 - **All other US locations:** $151,300.00 – $195,800.00 *Actual offers vary based on calibrated job level, qualifications, skills, competencies, and role proficiency.* ## Equal Opportunity & Safety Thumbtack is an equal opportunity workplace and committed to reasonable accommodations. They also note that scammers may impersonate the team—Thumbtack will never ask for money, banking info, or SSNs during hiring.
