Free resume; Komen-Waasten; Remote; EUR 161,000 - 209,000; Full time

Job summary

Thumbtack is seeking a Senior Full Stack Engineer for People Products to join a team building AI-enabled internal platforms. You’ll own end-to-end features, from frontend React/TypeScript to backend services, driving production-ready experiences for people programs.

You’ll redesign workflows across systems like Workday and Ashby, build safe API connectors, and shape permissioning for sensitive data. You’ll collaborate across data, product, and engineering to raise the bar and deliver impact.

Qualifications

• 5+ years of professional software engineering experience, owning end-to-end systems.
• Strong full-stack skills with React and TypeScript on the frontend and solid backend engineering.
• Experience with relational and non-relational data stores such as Postgres and DynamoDB.
• Experience building internal tools or business systems and integrating with SaaS APIs.
• Ability to reason about product workflows and decide what to build.
• Ability to operate autonomously as the lead engineer on a product area.

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.
