All of these areas are critical to our mission of building the People Operating System for Europe, used by thousands of organisations to manage their people, payroll, and processes.

• Design, build, and scale backend or fullstack systems used by thousands of customers
• Own features end-to-end, from problem definition through to production
• Work on distributed systems where reliability, performance, and correctness matter
• Collaborate closely with Product, Design, and other engineering teams
• Contribute to architectural decisions and continuously improve our systems
• Help shape engineering best practices and raise the bar across teams
• 
  

What We’re Looking For

• Solid backend skills (Java, Kotlin, or similar) and/or fullstack experience
• Experience building scalable, reliable systems
• Ability to navigate ambiguity and contribute to problem definition
• A strong sense of ownership and accountability
• Clear communication and collaboration skills
• 
  

Nice to Have (depending on team)

• Experience in payroll, fintech, or regulated domains
• Exposure to distributed systems or event-driven architectures
• Experience with cloud platforms (e.g. AWS)
• Interest or experience in AI-driven development workflows
• 
  

How This Role Works

This is a general application for Senior Software Engineers across Personio.

Rather than asking you to pick the “right” team upfront, we’ll work with you to find the best fit based on your experience and interests.

• You apply once
• We assess your experience, strengths, and interests
• We match you to the team and problem space where you’ll have the most impact
• 
  

This allows us to find the best fit for you across multiple product areas, rather than limiting you to a single role.

Locations & Working Model

This role can be based in:

• Munich
• Berlin
• London
• 
  

We follow a hybrid working model with 2 days per week in the office, giving you a balance of in-person collaboration and flexibility.
