Senior Software Engineer, L5 (Full-stack / Backend) - Recruiting (d/f/m) in London

Personio's intelligent HR platform helps small and medium-sized organizations unlock the power of people by making complicated, time‑consuming tasks simple and efficient. Our team of 1,500 Personios is building user-friendly products that delight our 15,000+ customers and their 1.5 million employees. Ready to make an impact from day one?

The Role

This role requires 2 days per week in the office and is based in Munich, Berlin or Dublin. As a Senior Software Engineer in our Recruiting team, you'll own and solve hard technical problems across one of Personio's biggest revenue drivers — the product customers use to run their entire hiring process — alongside Whistleblowing and Workforce Planning. You'll join a large, senior-heavy team that balances mature, high‑traffic systems with new, AI‑led capabilities like AI screening and smart candidate pipelines, taking real ownership of the parts of the product you work on.

What You'll Do

• Solve hard technical problems end to end — design, build, and ship reliable features across Recruiting and the team's products, owning them from problem to production.
• Own a meaningful slice of the product at team scope, taking responsibility for its quality, reliability, and the outcomes it drives for customers.
• Work product‑first — get to the heart of the customer problem and shape the solution, rather than implementing a predefined spec.
• Contribute to AI‑led capabilities like AI screening and smart candidate pipelines.
• Balance new build with legacy — modernise and extend existing systems while delivering new capabilities.
• Raise the bar on engineering quality through design discussions, code review, and pragmatic technical decisions.
• Collaborate cross‑functionally with Product, Design, and partner teams to deliver cohesive end‑to‑end solutions.

What You Need to Succeed

• Strong software engineering experience building and operating production systems (full-stack; strong backend or frontend depth both welcome).
• High autonomy — you can take an ambiguous, team- or product‑scoped problem and drive it to a solution without needing the path drawn for you.
• Strong ownership — you treat the reliability and outcomes of what you build as yours, well beyond the moment of shipping.
• A growth mindset — you actively seek feedback, learn quickly, and keep getting better at your craft.
• Solid system design skills within a team or product scope, comfortable in large codebases and evolving architectures.
• Product mindset — you care about the customer problem and influence the direction of the solution.
• Clear communication to explain technical decisions and collaborate effectively across disciplines.
