• Own MAAS-based bare-metal provisioning including region/rack controllers, PXE, and node lifecycle.
• Operate and maintain production Kubernetes clusters.
• Design and maintain multi-site networking across VLANs, L2/L3 routing, VPNs, firewalls, and DNS.
• Automate infrastructure provisioning and operations using Ansible, Bash/Python, and OpenTofu/Terraform.
• Build and maintain automated deployment workflows including PXE, Preseed, and cloud-init.
• Operate observability platforms using Prometheus, Grafana, Alertmanager, or VictoriaMetrics/VictoriaLogs.
• Define and improve SLIs, SLOs, alerting, and reliability practices.
• Lead infrastructure incident response, troubleshooting, and escalation.
• Maintain on-call processes and operational coverage across distributed environments.

Required qualifications

• 5+ years of hands-on SRE, Infrastructure, Systems, or Platform Engineering experience.
• Expert-level Linux administration, particularly Debian/Ubuntu.
• Strong production experience with MAAS and bare-metal provisioning.
• Expert-level, hands-on experience operating Kubernetes in production.
• Strong network engineering skills across VLANs, L2/L3 routing, bonding, VPNs, firewalls, and DNS.
• Strong automation skills with Ansible, Bash and/or Python.
• Experience with Terraform/OpenTofu and Git-based infrastructure workflows.
• Production experience with Prometheus/Grafana or comparable observability platforms.
• Experience with incident response, on-call operations, monitoring, alerting, and reliability practices.
• Experience with Proxmox, KVM/libvirt, OpenStack, VMware, or comparable virtualization technologies.
• Experience with bare-metal hardware, BMCs, IPMI/Redfish, storage, and hardware troubleshooting.
• Strong understanding of distributed systems, container orchestration, and infrastructure reliability.

Nice to have

• Startup or hyper-growth experience
• Experience operating GPU infrastructure or GPU-heavy Kubernetes/bare-metal environments.
• Proxmox VE with ZFS/Ceph and GPU passthrough.
• VictoriaMetrics / VictoriaLogs or similar large-scale observability platforms.
• NetBox or other IPAM / infrastructure inventory platforms.
• Vault, SOPS, Atlantis, or similar infrastructure security and automation tooling.
• Experience with Cloudflare APIs, DNS automation, or tunnels.
• Experience with UniFi or comparable site networking platforms.
• Experience with service mesh or advanced CNI implementations.
• Go experience, particularly for infrastructure tooling or custom exporters.

Benefits

• 100% remote with flexible working hours
• High-impact role with significant technical ownership and autonomy
• Work directly with bare-metal, Kubernetes, networking, and GPU infrastructure
• International, engineering-driven team
• Strong focus on automation, reliability, and infrastructure at scale
• Opportunity to shape the architecture and operational foundations of a growing cloud platform
