Senior Backend Engineer - Time & Money Domain (Munich, Berlin or London) d/f/m
About Personio At Personio, we're transforming the way Europe's SMEs manage their people - and we're just getting started. Our all-in-one HR and payroll platform is used by thousands of companies across the continent, and our mission is simple: empower businesses to put their people first.
The Role: Senior Backend Engineer - Time & Money Domain We're looking for a Senior Backend Engineer to join our fast-growing Time & Money (T&M) domain - a central pillar of Personio's product strategy. This role will see you tackling complex engineering problems in areas like time tracking, attendances, absences, and salaries - the very workflows that keep our customers' businesses ticking.
You'll join a domain with over 60 engineers, and work in cross-functional teams dedicated to solving deeply technical challenges with real-world impact. Whether it's building scalable systems to handle compliance across multiple countries or designing tools that help HR teams manage shifts more effectively - your work will matter.
What You'll Do

• Build Scalable Systems - Design and implement reliable backend services in Kotlin, Java, or Scala, optimised for performance and accuracy.
• Solve Real Problems - You'll work on customer-facing features that improve time-related workflows like tracking hours, managing absences, and automating salary logic.
• Collaborate Cross-Functionally - Work closely with frontend engineers, product managers, and designers to ship features from concept to production.
• Own Your Code - Take responsibility for quality, maintainability, and observability. If it breaks, you'll fix it - but you'll also learn from it.
• Keep Learning - As a senior engineer, you'll be expected to bring experience, but also curiosity - we're always iterating and improving.

What We're Looking For

• 3-5+ years of backend engineering experience in JVM-based languages (Kotlin, Java, Scala - we're flexible).
• A solid understanding of distributed systems, data modelling, and performance optimisation.
• Experience in building and operating data-intensive applications, ideally in regulated or compliance-heavy environments (FinTech or HRTech a plus).
• Strong problem-solving chops - someone who thrives in ambiguity and enjoys breaking down complexity.
• Bonus if you've dabbled in frontend or full-stack work and aren't afraid to cross the boundary when needed.

Why Join Time & Money at Personio?

• You'll work on some of the most impactful features in the platform, affecting thousands of users across Europe.
• Be part of a domain that's key to Personio's international growth and mid-market expansion strategy.
• Join a supportive and collaborative engineering culture where you're trusted to own your work and grow your career.

The Perks Bit

• Competitive compensation package including salary, pre-IPO equity, and great benefits.
• 28 days holiday (plus extra days based on tenure), Impact Days, and solid parental leave.
• Flexible hybrid working - office-based 50% of the time in either Munich, Berlin or London.
• Real opportunities for growth and learning, in a company that's going places.
