Join the team behind the employee experience at SumUp 🚀
At SumUp, our People Operations & Payroll team makes sure every employee has a smooth experience throughout their journey with us — from their first day to their latest promotion, and everything in between.

Why this role? 💡
You'll work alongside experienced People Operations and Payroll professionals, gain exposure to the full employee lifecycle, and develop practical skills that will set you up for a career in HR, Operations, Payroll, or People Analytics.
You'll learn how a global fintech supports hundreds of employees, manages payroll operations, and continuously improves the employee experience.

Ensure requests are handled quickly and nothing falls through the cracks
Contribute to creating a great employee experience
⚙️ Improve processes and keep things running smoothly
Maintain employee data across our HR systems
Update reports and trackers
Help improve processes and reduce manual work
Support the team with documentation and operational projects
What we're looking for 🔎
You're currently enrolled in a Spanish university and studying HR, Business Administration, Economics, or a related field
You're fluent in Spanish and English
You enjoy being organised and paying attention to the details
You're comfortable working with data and spreadsheets (Excel skills are a big plus!)
You're curious, proactive, and eager to learn
You're comfortable handling confidential information responsibly
You enjoy helping others and working as part of a team
Bonus points if you have ✨
Previous experience or studies related to HR, payroll, or people operations
An interest in payroll, HR systems, or process improvement
Experience using AI tools such as ChatGPT to work smarter and automate repetitive tasks
What you'll get 🌱
Real ownership and meaningful responsibilities from day one
Exposure to HR and payroll operations in an international fintech
The opportunity to learn from experienced People professionals
A chance to build skills that will open doors across HR, Operations, and Business functions
The experience of supporting a team that's helping shape the employee experience for hundreds of people across Southern Europe
If you're looking for an opportunity to learn, grow, and get behind the scenes of how a scaling tech company operates, we'd love to hear from you 💙
Why SumUp?
🌎 Work with a truly global, multicultural team from our Barcelona office.
🌈 Be part of a workplace that values diversity and inclusion, where every perspective is respected.
