• Develop and optimize CI/CD pipelines using GitHub Actions for secure, automated deployments • Implement, maintain, and monitor containerized applications (Docker, Kubernetes, ECS, or EKS) • Collaborate closely with engineering and security teams to ensure compliance with frameworks such as SOC 2, HIPAA, and NIST 800-53 • Automate cloud resource provisioning, scaling, and governance with reusable modules and policy-as-code • Manage and monitor infrastructure for performance, reliability, and cost optimization • Contribute to and enforce secure DevOps best practices (least privilege, secrets management, audit logging, vulnerability scanning) • Support platform integration for AI/ML workloads, container orchestration, and environment isolation • Other duties as assigned

• As a DevOps Engineer (m/f/d) on the DevEx team, your goal is to make the Internal Developer Platform (IDP) as intuitive and efficient as possible for our developers. • You act as the enabler who removes friction from the software delivery process. • You develop features of our IDP that enable teams to quickly and independently bring applications to the cloud. • Depending on where you live, you either work together with your team at our headquarters in Erkrath twice a week or you have the option to work up to 100% remotely. • You design and implement self-service capabilities within our Internal Developer Platform as well as high-performance CI/CD pipelines in GitLab. • You also establish modern deployment workflows using ArgoCD. • You support teams in taking full responsibility for their services — from the initial code commit to stable operation in the cluster. • As a mentor, you actively coach development teams and convey best practices in cloud-native development and deployment strategies. • In addition, you automate application delivery with Helm. • You act as a service-oriented bridge between development and operations and continuously improve the tools used across the developer journey.

• Develop and implement tools and processes to automate infrastructure management tasks; • Monitor and analyze system performance to proactively identify and troubleshoot issues; • Create and maintain detailed technical documentation of systems and procedures; • Collaborate with development teams to integrate reliability practices into the software lifecycle (DevOps); • Respond to incidents and resolve performance and availability issues quickly and effectively; • Ensure compliance with agreed SLAs and KPIs for production, QA, and development environments; • Maintain complex ecosystems, including the Data Lakehouse, Analytics Lab environments (AI/ML), and API integration via Apigee; • Work with automated CI/CD pipelines in Azure DevOps; • Operate with legacy environments while implementing modern architectures established by the Mobilize project, which uses cutting-edge technologies such as Control Tower, Transit Gateway, and IaC with Terraform;

• Design and build systems for large distributed web applications • Setup, monitor and administer web servers • Administer system security • Setup and configure necessary components and software • Administer redundancy, load balancing and failovers • Design and maintain High-load and High-availability infrastructure • Analysis of service infrastructure needs and their justification • Performance monitoring • Performance tuning via auto-scaling • Write and update scripts • Dockerizing Applications • Writing Ansible playbooks • Creating CI/CD pipelines for company projects
