Senior Infrastructure DevOps Engineer (f/m/d)

Your area of work: Within the CTO division, we operate and develop Deutsche Börse Group's group-wide IT infrastructure — spanning networks, data centers, cloud environments, our AI-driven SDLC platform, Group Data & Advanced Analytics, and Enterprise Architecture. As a Senior Infrastructure DevOps Engineer, you will take end-to-end ownership of the infrastructure reliability and security posture of our Agent Hub & Agent Chain platform: an event-driven, multi-agent orchestration system serving 1,000+ developers across all divisions. You will play a central role in shaping a regulated, high-availability environment governed by EU AI Act, DORA, and NIS2. Your responsibilities: Design, build, and operate production-grade Kubernetes clusters on GCP (with planned Azure extension), ensuring high availability, auto-scaling, and disaster recovery for the Agent Chain platform. Implement and enforce strict DevSecOps pipelines using GitHub Actions and Jenkins, integrating GHAS, Fortify, SonarQube, Aquasec, Black Duck, and Artifactory to systematically eliminate vulnerabilities before deployment. Develop and maintain all infrastructure as code using Terraform, ensuring reproducible, auditable, and version-controlled environments — including ephemeral sandboxes for agentic AI workloads. Build comprehensive observability stacks (logging, metrics, tracing, alerting) that enable proactive monitoring and rapid incident response across the multi-agent orchestration platform. Automate SBOM/CBOM generation and compliance-as-code controls to satisfy EU AI Act, DORA, and NIS2 requirements, ensuring every agent action is versioned and logged at the infrastructure level. Collaborate with AI/ML engineers and platform architects to bridge legacy infrastructure (25,000+ repositories, Jira On-Premise) with the target GitHub EU Cloud environment, maintaining uninterrupted service throughout. Your profile: Bachelor's degree or higher in Computer Science, Engineering, or a related field. 5+ years of hands-on experience in infrastructure engineering, DevOps, or Site Reliability Engineering. Expert-level proficiency in Kubernetes orchestration and at least one major cloud platform — GCP strongly preferred — including networking, IAM, and security hardening. Proven track record building and operating CI/CD pipelines with Infrastructure as Code (Terraform) and DevSecOps toolchains (GHAS, Fortify, SonarQube, Aquasec, Black Duck, Artifactory). Deep understanding of container security, supply-chain integrity (SBOM/CBOM), ephemeral environment provisioning, and production observability at scale. Strong ownership mentality with the ability to lead infrastructure decisions, drive operational excellence, and communicate effectively with cross-functional engineering teams. Proficiency in written and spoken English. Would be an advantage: Experience with regulatory compliance frameworks (DORA, NIS2, ISO 27001) in a financial services context. Familiarity with AI/ML serving infrastructure or agent orchestration platforms (e.g., LangGraph).
