- 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.
- 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.
