Responsibilities
- Maintain and support core infrastructure systems with deep knowledge of Linux (Debian/Ubuntu preferred)
- Work close to the metal: BIOS, IPMI, RAID setups, and hardware-level diagnostics are part of your comfort zone
- Design and maintain scalable networks using VLANs, L2/L3 routing, VPNs, and especially UniFi equipment
- Automate infrastructure provisioning and operations with Ansible, Bash/Python, and Git-based workflows
- Set up and manage observability stacks, including Prometheus/Grafana for metrics and Graylog, ELK, or Loki for log centralization
- 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
Requirements
- Expert-level Linux administration (preferably Debian/Ubuntu)
- Strong MAAS / Ironic / bare-metal automation experience (mandatory)

- Experience with monitoring and logging tools like Prometheus, Grafana, ELK/Graylog
- Comfort with custom deployment automation (PXE, Preseed, MAAS/Ironic)
- Proven experience with OpenStack, Proxmox, VMware, and container orchestration
Nice to Have
- Familiarity with firewall rules, access control, and security policies
- Experience with Cloudflare API for DNS management and tunnel setups
- IT asset management or software license tracking exposure is a plus
