Senior DevOps Engineer (f/m/d)
Job description
A hands-on platform engineering role owning the Kubernetes runtime and delivery platform for Ground Systems software, both on-premise and in the cloud. The engineer designs cluster architecture, builds provisioning automation, and maintains the shared GitLab CI/CD and Helm tooling product teams consume.
At a glance
- Work mode
- Remote
What you'll do
- Own and continuously evolve software platform capabilities enabling secure, reliable, and efficient software delivery
- Design and evolve the architecture of on-premise and cloud-hosted Kubernetes clusters and the surrounding platform: control-plane/worker topology, networking, storage, secrets management, and multi-environment promotion models
- Make and document architecture decisions as ADRs and standards that other teams build against, balancing reliability, operability, cost, and delivery speed
- Build and maintain automation that initializes, upgrades, and recovers clusters end to end, as well as certificate lifecycle, node drains and upgrades, storage provisioning and incident management
- Provision the on-premise and cloud-hosted substrate with Terraform and configure it with Ansible: HAProxy load balancers, NFS shares, DNS/resolv, secondary disks, domain joins
- Manage workloads with Helm: author, version, and maintain charts for application services and stateful components (Kafka, ClickHouse, MQTT brokers, MSSQL), with automated semVer releases driven from merge requests
- Practice GitOps with ArgoCD: installation, Azure Entra ID SSO and RBAC, and reconciliation troubleshooting across clusters
- Own shared GitLab CI/CD library for jobs, templates, rules, semVer/release/changelog automation
- Operate developer-facing platform tooling and the container toolchain behind those pipelines including observability
What we're looking for
- 5+ years in Platform Engineering, DevOps, Software Infrastructure or SRE-type roles
- Strong Linux proficiency, comfortable on the shell, troubleshooting systemd, networking, DNS, storage, permissions and file systems
- Deep Kubernetes experience beyond the managed-service basics: cluster bootstrapping, CNI, ingress/load balancing, storage classes, RBAC, upgrades, and cert management
- Strong hands-on GitLab CI/CD experience, including reusable components and pipeline-as-a-product maintenance
- Practical GitOps with ArgoCD
- Solid Microsoft Azure background: AKS, Container Registry, Key Vault, managed identity/service principals and least-privilege RBAC
- IaC experience with Terraform and Ansible
- Comfortable with containerization: image building and hardening, Helm authoring and versioning
- Proven ability to design and document architecture, and to defend trade-offs to both engineers and stakeholders
- Scripting proficiency in Python, Bash and PowerShell
- Pragmatic support sensibility: you help teams debug a broken pipeline or pod the same day
Nice to have
- Data platform understanding for Kafka, ClickHouse, MQTT/streaming ingestion, MSSQL, Databricks or similar fit into an operational data pipeline
- Working knowledge of identity/networking at the edge: HAProxy, VLANs, multicast, corporate DNS and proxy constraints
- Experience with Agentic Engineering workflows and engineering productivity tooling
- Exposure to aerospace, mission-critical, or export-controlled/regulated environments
- Familiarity with .NET build and release pipelines
