Product Engineer — Working Student

Working Student - Product Engineer Over 4 million merchants use our card readers to process payments in 34 countries. As we build a world where every business can thrive, we continually expand our range of products and services. We are a truly global fintech company, with 3,000+ people from 93 nationalities spread across 22 offices on four continents. As the People Tech team, our mission is to enable long-term scalability by fostering a data-informed culture through seamless systems and a people-centric employee experience. As our Product Engineer - Working Student, your first mission will be to help us 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. If a direction proves valuable, you may help grow it into a standalone internal app - from interface and APIs to data models, authentication and integrations - alongside People Tech and engineering partners. This is a real product challenge, not a side quest: you will learn across discovery, UX, frontend, testing and product decisions, supported by mentorship and code review. You will collaborate with Product Owners, process owners, people tech and workday specialists, sumuppers, managers, people partners, people analytics and senior stakeholders, with potential exposure to backend development, integrations and production delivery. If your favourite way to answer “what if?” is to build it, you will fit right in. 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. Prototy
