Job description

Описание

Location: Fully remote, EU timezone (CET ±2h) Start date: ASAP Languages: Fluent English required Industry: Cloud Computing / GPU Infrastructure Pragmatike is hiring a Senior SRE / Infrastructure Engineer to help operate and scale a distributed infrastructure platform spanning bare-metal GPU nodes, Kubernetes, virtualization, networking, and multi-site environments. You’ll work close to the infrastructure itself, from BMCs, hardware and MAAS provisioning through Kubernetes, networking, observability, automation, and site operations. This is a hands‑on role for someone who enjoys owning infrastructure end‑to‑end, building reliable systems, and automating everything that can be automated. Startup or hyper‑growth experience is a strong plus: autonomy, ownership, and speed matter here.

Задачи

• Operate and maintain large-scale Linux infrastructure across Debian/Ubuntu-based bare-metal and virtualized environments.
• Own MAAS-based bare-metal provisioning, including region/rack controllers, PXE, commissioning, cloud-init, node lifecycle, and API/CLI automation.
• Operate and maintain production Kubernetes clusters, including upgrades, node pools, networking, storage, security hardening, and troubleshooting.
• Design and maintain multi-site networking across VLANs, L2/L3 routing, bonded interfaces, VPNs, firewalls, and DNS.
• Automate infrastructure provisioning and operations using Ansible, Bash/Python, OpenTofu/Terraform, and Git‑based workflows.
• Build and maintain automated deployment workflows including PXE, Preseed, and cloud‑init.
• Operate observability platforms using Prometheus, Grafana, Alertmanager, VictoriaMetrics/VictoriaLogs, or comparable tooling.
• Define and improve SLIs, SLOs, alerting, and reliability practices across infrastructure and platform services.
• Lead infrastructure incident response, troubleshooting, escalation, and post‑incident improvements.
• Maintain on‑call processes and operational coverage across distributed environments.
• Work close to the hardware layer, including IPMI/Redfish, BMCs, RAID, storage, hardware diagnostics, and GPU infrastructure.
• Manage virtualization platforms including Proxmox, KVM/libvirt, OpenStack, or VMware, including GPU passthrough where required.
• Build and maintain internal infrastructure tooling for host discovery, configuration, IPAM, hardware health, and operational automation.
• Own infrastructure lifecycle activities including site onboarding, maintenance, decommissioning, drift detection, and operational runbooks.
• Work closely with engineering and cross‑functional teams to improve reliability, resource utilization, and operational efficiency.

Требования

• 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, including cluster lifecycle, networking, storage, upgrades, and troubleshooting.
• 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.

• Strong understanding of distributed systems, container orchestration, and infrastructure reliability.
• Experience with infrastructure security including RBAC, firewalls, network policies, secrets management, and security hardening.
• Ability to create SOPs, runbooks, and operational processes from scratch.
• Comfortable working autonomously in a fast‑paced, engineering‑driven environment.
• 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.
• Experience with Ceph or distributed databases running on bare metal.
