Senior Full-Stack Engineer for AI-Powered People Platform

Thumbtack; United States; Remote; USD 179,000 - 232,000; Full time

Job summary

Thumbtack’s Business Applications team is expanding an AI-enabled internal platform for HR and recruiting systems. You’ll own end-to-end engineering, build secure, scalable workflows, and design reusable building blocks for internal tools across the org.

Join a team working with People Products & Data, TPMs, data scientists, and engineers to ship impactful solutions while maintaining strict data governance and privacy.

Qualifications

• 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.

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.
