Senior Software Engineer – Time & Money (d/f/m)
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.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
