About the Team
You will join an operations and development team.
Deployment for our CRM is currently handled by a dedicated DevOps team using GoCD pipelines, Ansible, and virtual machines across multiple data centers. We are currently using Docker, Docker Swarm, and Portainer for our test environments.
Deployment for our ai platform is GitOps-driven via ArgoCD and Kustomize on Kubernetes, with Jenkins/Harbor for CI and HashiCorp Vault (External Secrets Operator) for secrets. Cilium CNI with BGP Control Plane handles networking across prelive and live clusters. Local environments use Docker Compose, elastic search, ClickHouse, MinIO, and Redis; Langfuse runs across all environments with ClickHouse as its backend.
We want to move toward a more dynamic infrastructure model, potentially based on Kubernetes for all our systems where possible. Our goal is to gain speed in spinning up environments for testing purposes but also more flexibility in a potential hybrid production environment.
You will work alongside our existing DevOps team and experienced engineers, who will support you as you grow into the more advanced parts of our stack.

We are looking for a DevOps Engineer with around 3–5 years of experience who will work directly with the development teams and take an active part in the next stage of our infrastructure.
This role combines hands-on Linux administration, container orchestration, networking knowledge, and modern DevOps practices. You will help us move from VM-based deployments toward a more scalable, orchestrated platform.
