Product Engineer — Working Student

As a Product Engineer - Working Student, your mission is to help rethink Feedback and Team Reviews: learn how the process works today, find the friction and turn promising ideas into product experiences that colleagues can test. The work starts frontend-first: build realistic prototypes in React, Next.js or similar and explore a simpler product layer over Workday, our system of record.

What you'll do

• Find the right problem: Speak with process owners, employees and managers to understand Feedback and Team Reviews, identify friction and decide what is worth solving first.
• Shape a focused product slice: Turn requirements, questions and constraints into clear user journeys and an MVP that can teach us something useful.
• Prototype and iterate quickly: Build realistic frontend experiences in React, Next.js or similar; compare directions, test assumptions and adjust when the evidence points somewhere better.
• Design for different kinds of work: Create accessible, intuitive flows for office-based teams, metrics-driven Field Sales colleagues and on-site teams without building three separate products.
• Think end to end: If the concept is validated, help evolve it towards a standalone app while considering APIs, data, authentication, privacy, deployment, integrations and what should remain in Workday.
• Use AI as a co-pilot, not an alibi: Use tools such as Cursor, GitHub Copilot, v0, Lovable or similar to accelerate development while still understanding, checking and owning the result.
• Make the learning visible: Demo your work, explain decisions and trade-offs, respond to feedback and document the findings and technical choices that should shape the next version.

What you'll need

• Student status. You are currently enrolled at a university and available for a part-time role based in Berlin.
• Modern web development skills. You have built web applications with React, Next.js or a similar frontend framework.
• Product-minded builder. You care about the user's goal and accessibility, and can turn an ambiguous problem into the simplest useful solution, test it and iterate.
• Full-stack and AI curiosity. You want to learn how APIs, data and services turn an interface into a reliable product, and can use AI-assisted tools while still understanding, checking and owning the result.
• Clear, team-first communication. You can explain what you built end to end, make technical choices understandable, ask for input and respond well to feedback.

Nice to have

• Backend and integration foundations. Some experience with Node.js, TypeScript, Python, databases, APIs, serverless functions, Supabase, Firebase, AWS or comparable technologies.
• Identity and data concepts. A basic understanding of OAuth, SSO, permissions or responsible data handling.
