Senior Site Reliability Engineer (MAAS)

About the role

Pragmatike is hiring a Senior SRE / Infrastructure Engineer to operate and scale a distributed infrastructure platform spanning bare‑metal GPU nodes, Kubernetes, virtualization, networking, and multi‑site environments. The role is fully remote within EU timezones and involves hands‑on ownership of infrastructure end‑to‑end.

Key responsibilities

• Operate and maintain large‑scale Linux infrastructure on Debian/Ubuntu bare‑metal and virtualized environments.
• Own MAAS‑based bare‑metal provisioning, including PXE, commissioning, cloud‑init and API automation.
• Run production Kubernetes clusters: upgrades, node pools, networking, storage, security hardening and troubleshooting.
• Design and maintain multi‑site networking (VLANs, L2/L3 routing, bonded interfaces, VPNs, firewalls, DNS).
• Automate provisioning and operations with Ansible, Bash/Python, Terraform/OpenTofu and Git‑based workflows.
• Manage observability platforms such as Prometheus, Grafana, Alertmanager and VictoriaMetrics/VictoriaLogs.
• Lead incident response, on‑call coverage, post‑mortem analysis and reliability improvements.
• Handle virtualization platforms (Proxmox, KVM/libvirt, OpenStack, VMware) and GPU passthrough where required.

Required profile

• 5+ years of hands‑on SRE, infrastructure or platform engineering experience.
• Expert‑level Linux administration (Debian/Ubuntu) and production experience with MAAS.
• Deep experience operating Kubernetes in production, including networking, storage and upgrades.
• Strong network engineering skills across VLANs, routing, bonding, VPNs, firewalls and DNS.
