Professional Background:

Were looking for an Infra/DevOps engineer with deep expertise in Metal-as-a-Service (MAAS) and bare-metal automation. You should have a strong Linux background and direct experience managing large-scale on-prem and cloud-adjacent infrastructureshundreds of nodes across multiple sites.

Startup or hyper-growth experience is a strong plus. Autonomy, speed, and problem-solving are essential.

  • Build tooling for server discovery, config auto-generation, automated OS deployments, PXE/Preseed/Cloud-init, and strong MAAS-based provisioning.
  • Integrate and/or develop internal APIs for tracking compute and GPU resource allocation, as well as external APIs (billing, monitoring, OpenStack, etc.).
  • Deploy and maintain virtualization and orchestration systems such as OpenStack (preferably with Kolla-Ansible), Proxmox VE, or VMware ESXi.
  • Support container-based workloads and isolate services efficiently.

What You Bring:

  • Expert-level Linux administration (preferably Debian/Ubuntu).
  • Strong MAAS / Ironic / bare-metal automation experience (mandatory).
  • Excellent networking fundamentals: VLANs, routing, VPNs.
  • Infrastructure as Code (Ansible), scripting (Bash/Python), GitOps.
  • Experience with monitoring and logging tools like Prometheus, Grafana, ELK/Graylog.
  • Comfort with custom deployment automation (PXE, Preseed, MAAS/Ironic).
