About The Role

We're hiring a Senior Infrastructure Engineer — Operations & Reliability to help operate and improve Nscale's OpenStack-based cloud infrastructure. You should have a passion for cloud infrastructure and open-source platforms to join our expanding System Engineering function. This role is pivotal in establishing our follow-the-sun operational model, providing critical coverage for live services during regional operational windows.

You will support live services, resolve incidents across Linux, OpenStack, networking, and virtualization, and work with infrastructure and systems engineering colleagues across time zones. The role combines hands-on operations with opportunities to automate recurring work and improve platform reliability. You will also collaborate with Fleet Management, Network Operations, and other engineering teams when issues cross system boundaries.

What You’ll Be Doing (Responsibilities)

Live Service Operations: Monitor, triage, and resolve complex Level 2 (L2) incidents across our Unix/Linux and OpenStack cloud environments to safeguard customer SLAs.
Platform Support: Provide hands-on operational support and maintenance across compute, networking, and virtualization layers, specifically focusing on OpenStack Neutron (SDN) and OpenStack Ironic (bare-metal provisioning).
Follow-the-Sun Coverage: Operate effectively within a rotating shift framework to maintain seamless system reliability during US hours, collaborating and learning from EMEA team peers, paving the way for future APAC systems onboarding.
Knowledge Management: Convert real-time troubleshooting insights into structural capital by creating, refining, and updating standard operating procedures (SOPs) and technical runbooks. Follow up on incidents with documented root-cause analysis and corrective action.
Cross-Functional Collaboration: Work with infrastructure and systems engineering colleagues and partner teams (like Fleet Management, Network Operations, etc.) to diagnose complex issues, make safe platform changes, and escalate when specialist input is needed.
Automation and SW Stack Evolution: Turn recurring issues into lasting improvements through automation, monitoring, configuration changes, and collaboration with the relevant engineering teams.

About You (Requirements)

Linux/Unix Systems Administration: Proven commercial experience managing and troubleshooting Linux-based infrastructure at scale.
OpenStack Core Competency: Hands-on experience working with or maintaining OpenStack ecosystems in production or large-scale staging environments.
Virtualization Insights: Practical exposure to hypervisors and virtualization technologies (e.g., KVM, Proxmox).
Analytical Triage Mindset: A methodical, evidence-led, and analytical approach to incident investigation, performance bottlenecks, and root-cause analysis.
Communication & Documentation: Excellent English communication skills, with a proactive approach to technical writing and knowledge sharing.

Nice to Have

Exposure to cloud-native technologies and container orchestration (Kubernetes).
Familiarity with infrastructure automation tooling (Ansible, Terraform, Python/Bash scripting).
Experience with data-centre buildout systems, hardware lifecycle processes, or infrastructure automation.
