Job Description

DigiHUB MARE is the way to digital future!

One Backend for multiple Frontends

Uncompromising customer focus - Uncompromising IT

PURPOSE:

At DigiHub MARE, we are pioneers in the development of applications for the end customers in Germany, the employees of Deutsche Telekom Technik, Deutsche Telekom Field Service and Deutsche Telekom Service and for technical solutions to support customer side processes. Our mission is to deliver groundbreaking solutions that redefine the standards of excellence. We believe in innovation, integrity, and inclusivity. If you're passionate about pushing boundaries and making a tangible impact, you'll find your second home with us.

The Opportunity:

We’re looking for a Senior DevOps Engineer who loves turning complex cloud operations into smooth, automated delivery. You’ll work hands-on with Telekom’s cloud platforms — OTC and GCP — and make sure deployments are not only running, but running scalable, reliable, and repeatable .

Your playground spans the full toolchain: GitLab CI pipelines that ship fast and safely, Docker & Kubernetes for modern runtime operations, and strong monitoring with Grafana, Prometheus, and ELK so we spot issues before users do. If you’re the person who sees manual steps and thinks “this should be automated”, and you enjoy improving performance and stability on Linux systems, you’ll feel right at home.

WHAT WILL YOU DO:

• DevOps & Platform Lifecycle Ownership: Design, implement and take ownership of end-to-end DevOps lifecycles across multiple solutions and projects, ensuring reliable, scalable, and maintainable cloud-native platform operations.
• Multi-Cloud Platform Engineering: Architect, build and operate secure and scalable cloud platforms across major providers such as Google Cloud Platform (GCP), Microsoft Azure, and Amazon Web Services (AWS), leveraging cloud-native services and automation to enable resilient infrastructure.
• Infrastructure as Code & Automation: Implement and maintain infrastructure using Infrastructure-as-Code frameworks such as Terraform, ensuring reproducible, version-controlled, and auditable infrastructure provisioning and configuration management.
• Container Platforms & Orchestration: Design, deploy and operate containerized workloads using Docker and Kubernetes, optimizing cluster architecture, resource utilization, and high availability for production-grade environments.
• CI/CD & Release Engineering: Build and maintain robust CI/CD pipelines to automate build, test and deployment processes, enabling frequent, reliable and independent releases of platform and application components.
• Observability & Reliability Engineering: Establish comprehensive monitoring, logging and alerting using tools such as Prometheus, Grafana and centralized logging stacks, ensuring high platform reliability, rapid incident detection and efficient troubleshooting.
• Incident Management & Operational Excellence: Define and implement operational best practices, including incident response procedures, automated remediation strategies, and performance optimization to maintain platform stability and availability.
• Cross-Team Collaboration & Technical Leadership: Collaborate with cross-functional engineering teams to drive DevOps culture, platform standards and best practices, while mentoring junior engineers and supporting knowledge sharing within the organization.
