Senior Software Engineer – EO – Munich/London (d/f/m)
Location
Munich or London (2 days per week in the office).
The Role
We’re hiring a Senior Software Engineer to join our EO team at Personio. This is a role that sits in a senior, high-trust engineering team working on core platform capabilities that power large parts of the Personio product.
EO sits at the intersection of platform and customer-facing product. The systems built here are used by many other teams across Personio and directly impact how admins manage company structures, permissions, and employment-related data.
This role is primarily back-end focused, with a strong preference for engineers who are comfortable contributing to front-end work when needed (React). You don’t need to be a classic full-stack engineer, but you should be happy operating across the stack where it makes sense.
What You’ll Be Working On
Over the next 6-12 months, the team will spend most of its time on new customer-facing feature development, with the remaining time focused on modernising and improving existing foundations.
What You’ll Work On
- Evolving core platform capabilities that power how organisations are represented and managed in Personio (data models, APIs, and workflows)
- Building secure, scalable backend services that support complex permissioning, delegation, and governance needs
- Improving foundations and system quality (performance, observability, robustness, tech-debt reduction, and operational excellence)
- Designing for change at scale, including backward-compatible migrations, versioning strategies, and safe rollout patterns
- Cross-team collaboration with multiple product and platform teams to ensure changes integrate cleanly and scale safely across the ecosystem
What You’ll Do
- Design, build, and evolve scalable backend systems that are used across Personio
- Work in ambiguous problem spaces, proactively identifying missing information and dependencies
- Balance product thinking with technical excellence, shaping solutions rather than just executing tickets
- Collaborate closely with Product and Design, while also managing a wide range of technical stakeholders
- Contribute to a senior-heavy team through code reviews, design discussions, and technical leadership
- Occasionally contribute to front-end work where it unblocks delivery or improves outcomes
What We’re Looking For
- Strong experience as a backend engineer working on production systems
- Comfort operating in ambiguous environments with changing priorities
- A product-minded approach to engineering and problem solving
- Ability to communicate clearly with engineers, product managers, and teams across the organisation
- Experience with Java, Kotlin, or similar languages is helpful, but not essential
- Front-end experience (React) is a strong plus, but not a hard requirement
Why Personio
Personio is an equal opportunities employer, committed to building an inclusive culture where everyone feels supported.
We value in-person collaboration while offering flexibility. This role requires 2 days per week in your contracted office location, with the remaining days flexible. You’ll also get 20 Flex Days per year to work remotely from other locations.
Our benefits include:
- Competitive salary, benefits, and pre-IPO equity
- 28 days paid holiday, plus additional days after 2 and 4 years
- One fully paid Impact Day per year
- Generous family leave, mental health support, and sabbatical options
- Regular team events, office snacks, drinks, and weekly catered lunches
