• Write a small app/plugin/service to automate, i.e. infrastructure checks or support Observability • Build or extend Terraform modules and contribute to Platform Engineering around Observability • Use APM tools like Dynatrace to find performance hotspots (and issues) nobody sees yet • Investigate a tricky production issue by combining logs, metrics and traces into a clear story • Optimize a distributed system that is under a heavy load • Lead improvements after incidents - root cause, patterns, architectural recommendations • Collaborate with developers to shape feature design so that reliability is built in, not added later • You will have real influence. We take suggestions seriously. If something should be redesigned, we redesign it.

• Lead a high-performing DevOps/Platform squad responsible for infrastructure-as-code, observability, CI/CD, and cloud operations. • Drive the design and implementation of scalable, secure, and highly available cloud environments (primarily Azure) using Terraform and modern DevOps tools. • Spend approximately 30% of your time hands-on, contributing to IaC, automation scripts, monitoring setups, and critical system improvements. • Guide your team through effective incident management, ensuring rapid resolution, root cause analysis, and continuous improvement of system reliability. • Champion SRE best practices including error budgeting, SLAs/SLOs/SLIs, and proactive reliability engineering. • Coach and mentor engineers through pairing, reviews, and architectural discussions. • Collaborate with product and engineering stakeholders to define platform roadmaps and priorities. • Continuously evolve our CI/CD pipelines, GitHub workflows, release strategies, and operational playbooks. • Foster a DevOps culture with a strong focus on automation, security, observability, and accountability. • Ensure effective Agile ceremonies and delivery practices are followed, adapting where needed for high-performing operations-focused teams.

• Extend and optimize our build, release and packaging system. • Help improve our Continuous Integration, Continuous Deployment (CI/CD) pipelines and build system. • Build and maintain our build infrastructure. • Work closely with C++ product developers to understand their workflows and how to improve them.

• As a DevOps Engineer (m/f/d) on the DevEx team, you will help us continuously improve our Internal Developer Platform (IDP). • Your goal is to make developers' day-to-day work more efficient through automated processes and streamlined workflows. • You will support the rollout of new features and learn how to sustainably remove friction points in software delivery. • Depending on your place of residence, you will either work together with your team at the headquarters in Erkrath twice a week or you will have the option to work up to 100% remotely. • You will contribute to implementing self-service capabilities within our Internal Developer Platform and to building CI/CD pipelines in GitLab. • You will also support the adoption of modern deployment workflows using ArgoCD. • Together with your team, you will support development teams in taking responsibility for their services — from code commit to operation in the cluster. • In addition, you will automate application deployment with Helm. • You will learn best practices in cloud-native development and apply them under guidance in real projects. • You will contribute to the continuous improvement of developer-journey tools and assist with technical questions.
