Time & Money
Full Time
London
About the Role
Join the Time & Money domain at Personio, where we’re building critical systems that sit at the heart of our product.
The Time domain powers how employee working time, absences, and compensation data are captured and processed. This data directly impacts payroll accuracy, compensation workflows, and ultimately customer trust. As we expand into the mid-market, this area is becoming increasingly central to enabling business growth.
You’ll work on high-impact, often greenfield problems, helping shape how Time data flows seamlessly into Money and Payroll systems in a scalable, reliable way.
Why This Role Exists Now
We’re at a pivotal stage of growth.
Time & Money sits at the intersection of payroll, compensation, and core HR
The team owns a
business-critical initiative tied to expansion revenue
Much of the problem space is still evolving, with scope for strong engineering ownership
This means we need engineers who are comfortable navigating ambiguity, shaping solutions early, and building systems that scale with the business.

Design services that ensure Time data flows accurately into Payroll and Money systems

What We’re Looking For
Strong backend engineering experience in production systems
Experience building scalable, reliable services (ideally distributed systems)
Solid programming skills in Java, Kotlin, or similar
Comfort working in ambiguous, fast-paced environments
A strong sense of ownership and accountability
Clear communication and collaboration skills
Nice to have:
Experience working on systems involving time tracking, payroll, fintech, or other regulated domains
Exposure to data-heavy or correctness-critical systems
Full-stack experience (helpful but not required)
Team & Environment
High-performing, ambitious team based in London
