About the Opportunity

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.

What You’ll Do
  • 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.

What We’re Looking For
  • 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.

  • Experience with bare-metal hardware, BMCs, IPMI/Redfish, storage, and hardware troubleshooting.

  • 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.

Nice to Have
  • 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.

  • Experience operating infrastructure across multiple sites and timezones.

  • Experience establishing SRE frameworks and reliability practices in growing organizations.

Why Join Us
  • 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
