Junior People Operations Partner (1 year FTC)

The People Ops & Payroll Eastern Europe team keeps the engine running for Sum Uppers across the region — making sure every hire, change, and payroll cycle is handled accurately, on time, and with care. In Bulgaria alone, we support 520+ employees, and as the business continues to grow, reliable People Ops execution is what makes that growth feel seamless for the people living it every day.

This role sits at the heart of that — owning the day-to-day administration for Sum Up Bulgaria, being a dependable point of contact for employees and managers, and helping us build a better, more consistent People Ops experience as we scale. The role is set to start as a one year fixed-term contract.
