Senior Full Stack Engineer, People Products

Thumbtack is building People products that improve how employees, managers, and People specialists access guidance and complete workflows. The Senior Full Stack Engineer will take AI-enabled People experiences to production, build secure integrations and permissioning for sensitive data, and shape reusable internal platform capabilities.

Responsibilities:

• Take early People products to production and grow them into a suite of experiences, across standalone products, plugins, and everyday tools, that move from answers and insights to personalized guidance, proactive support, and approved actions
• Redesign workflows across Workday, Ashby, and other systems, from approved headcount to open requisition and accepted offer to onboarding
• Build APIs and connectors, including MCP connectors, that let AI tools safely access relevant context and complete workflows on users’ behalf
• Design the permissioning model for confidential People data: identity, person-level authorization, what reaches the model, retention, approvals, and audit
• Partner with People Products & Data on instrumentation and AI evaluations to measure quality, enforce boundaries, and improve products
• Create the reusable building blocks that let People team members safely build simpler tools themselves, so your time goes to the most complex, highest-impact work
• Own what you ship across the stack, from React and TypeScript through service code and data models, and set technical direction with non-engineering partners by shaping ambiguous problems, pushing back on scope, and proposing simpler paths

Requirements:

• [5+] years of professional software engineering experience, including owning systems end to end from ambiguous problem to production
• Strong full-stack skills: React and TypeScript on the frontend, and solid backend engineering. 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)
• Sound judgment with sensitive data: authentication and authorization, least-privilege access, auditability, and privacy-aware design
• Experience building internal tools or business systems — people, sales, marketing, finance, or operations tooling — and integrating with SaaS platforms through their APIs
• Real product judgment: you can look at a workflow, decide what to build, and say what to cut
• Comfort operating with a high degree of autonomy as the primary engineer on a product area, and a track record of raising the technical bar for the people around you
