What the job involves

• Join the Time & Money domain at Personio, where we’re building critical systems that sit at the heart of our product

• This means we need engineers who are comfortable navigating ambiguity, shaping solutions early, and building systems that scale with the business
• Build and evolve backend systems that power time tracking, absences, and compensation workflows
• Design services that ensure Time data flows accurately into Payroll and Money systems
• Improve system reliability, scalability, and performance in a correctness‑critical domain
• Work on greenfield initiatives where requirements are still being shaped
• Collaborate closely with Product, Design, Payroll, and Platform teams
• Take ownership of features end-to‑end, from design through to production
• Contribute to architectural decisions and raise the engineering bar across the team
