Senior Software Engineer – Backend / Fullstack (d/f/m)

Product, Technology & Design

Full Time

Munich, Berlin or London

About The Role

We’re hiring multiple Senior Software Engineers across Personio.

This is an opportunity for experienced engineers who want to work on meaningful, high-impact problems across a range of product areas. Depending on your experience and interests, you could join teams working on:

• Payroll & Fintech systems
• Time & Attendance
• Core HR platform
• Workflow automation
• Integrations & platform services
• AI-powered product experiences
  
  

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.

What You’ll Do

• 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

• Strong experience as a Software Engineer in production environments
• 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
• AI Fluency: You have hands-on experience using AI to improve your workflow, and the sound judgment to know exactly when to rely on it and when to step in yourself.
  
  

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.

• Munich

• 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.
