The DX Engineer is a high-impact, cross-functional role at the heart of our engineering organisation. We support our internal engineering teams throughout the complete development lifecycle of Personio, and we play a key role in enabling them to deprecate our monolith and create a highly scalable microservices architecture with modern tech stacks.

Do you get excited about developer tools, build pipelines, continuous delivery and deploying, running and monitoring highly scalable applications on Kubernetes? Are you interested in guiding, helping and sharing knowledge with fellow developers? Are you eager to solve the challenges that engineers face to improve the entire department’s productivity and provide a delightful developer experience? Then this role is for you!

Responsibilities

• You will research, engineer and experiment with new ways to improve developer workflows and devops practices to reduce our Lead Time to Production and increase Deployment Frequency
• You will maintain and improve Personio’s dev environments and build infrastructure. Your scope will include everything from how services are developed and tested locally, to how they are built and integration-tested using our Gitlab CI/CD pipeline, to how they are rolled out, run and monitored in our production Kubernetes cluster.
• You will foster relationships and work closely with product teams to support them in the migration of our monolith to microservices architecture, understand their challenges and propose result-oriented solutions to improve their productivity.
• You will also spend time teaching engineers (especially new joiners) how to use our tools, whether by giving internal talks, organising internal onboarding workshops or writing documentation and tutorials.
  
  How we work:
• We are transforming our PHP application into Golang and Kotlin microservices!
• We are a product company so our teams are organised in a mission-based cross-functional fashion. You will work in the Tech Platform, alongside other Backend/Devops Engineer, SRE, Security Engineers and QA Engineers
• We have a “you built it, you run it” attitude and CI/CD is our second nature - we use AWS, Docker, Kubernetes, and GitLab to implement it!

• Over 5 years of software engineering experience building and designing scalable applications, tools or distributed systems. You understand the needs of software engineers working in product teams, you’ve been in their shoes, and can empathise with them. You want to help your fellow engineers to achieve maximum efficiency.
• You have a strong expertise with at least one of our tech stacks: Java/Kotlin (JVM, Gradle, SpringBoot), PHP (Laravel) or Golang. In particular you’re comfortable with the intricacies of their build ecosystems (build tools, tasks runners, etc.) and you understand how to monitor and manage them in a containerised production environment.
• You have a deep understanding  and an interest for DevOps tools and technologies such as: Kubernetes, AWS, Sentry, DataDog, Docker, Git/Gitlab, Flagger, and Linkerd, as well as deployment automation (CI/CD pipelines, blue/green and canary deployments).
• You’re comfortable writing, documenting and distributing robust and delightful scripts, CLI tools and plugins for developers (we mostly use Golang and Python for that).
• You’re interested in development processes and practices (merge requests, approvals, trunk-based vs branch-based development, etc), and are eager to optimise them.
• You want to work with a very technical team on developer-facing tools and services, and you like writing great technical documentation and useful tutorials.
• You love data driven decision making and the metrics of Developer Experience - Lead Time and Deployment Frequency.
• You have an excellent written and spoken English (level C1/C2 on the CEFR scale)
• We are experiencing rapid growth and are “building our plane while flying it” so bring your agile mindset to the table!
• You embrace feedback - no one is perfect, neither are we. So let’s make this an opportunity to praise and learn from each other.
• Finally, you have a good sense of humour. Have fun with us, learn with us from mistakes and bring your good vibes!
