Jobbeschreibung

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 or Dublin.

Join us to shape the future of software in the underserved and high-impact HR technology industry. Your work will have a direct and tangible impact on customers, offering ownership and the chance to make a meaningful difference. As we prepare for significant growth, you'll face exciting challenges and have the opportunity to influence our path toward becoming one of the world's leading tech companies.

What You'll Do

• Design and support platform solutions that empower 300+ developers across 40+ product teams (e.g., internal tooling, standards, SDKs, and middleware that improve developer workflows)
• Build and evolve our gRPC-GraphQL gateway that connects frontends with backend services
• Create internal tools and libraries/SDKs to enhance developer productivity and platform adoption
• Analyse and optimise platform systems to enhance scale, performance, reliability, and developer experience
• Work hand-in-hand with product teams to ensure seamless platform integration and a strong feedback loop
• Document platform capabilities and run internal training sessions
• Collaborate with other platform teams to create a coherent developer platform
• Drive technical excellence by simplifying platform architecture and managing technical debt

What You Need To Succeed

• 3+ years of experience in platform engineering and/or backend development
• Strong programming skills in a JVM language (e.g., Kotlin, Java, Scala); Kotlin is a bonus
• Experience building production-grade backend systems with attention to reliability, performance, and maintainability
• A strong engineering mindset for enabling other teams: you enjoy reducing friction, improving “paved roads,” and raising standards through tooling and automation
• Experience with modern engineering practices for high-availability platforms, including testing strategies, performance optimization, and reliability considerations
• Experience in establishing observability practices and instrumenting platforms for monitoring and debugging
• You are data-driven and passionate about using metrics to evaluate platform performance and adoption
• Strong communication skills, with the ability to build relationships across teams
• Comfortable working in a highly collaborative environment, engaging in code reviews, pair programming, and cross-team discussions

Nice to Have

• Experience building developer tooling / Developer Experience initiatives (e.g., internal platforms, CLI tools, SDKs, templates, golden paths, CI/CD improvements)
• Experience with gRPC and GraphQL, particularly in building middleware or gateway layers
• Experience working with Kafka
• Strong Gradle experience

Note: We welcome Backend Engineers who are excited to move closer to Developer Experience and platform enablement. Direct DevEx/platform-tooling experience is great, but not required.
