- Manage customer and leadership reporting on service health and attend customer service reviews.
- Keep the team's ITSM, on-call, and operational tooling fit for purpose.
Requirements
- Solid hands-on engineering experience in infrastructure operations or site reliability engineering (Linux, networking, storage, Kubernetes or virtualisation).
- Technical depth to lead recovery, question diagnosis, and judge escalation evidence.
- Significant experience leading a 24/7 operations, SRE, or production engineering team in a large-scale hosting, HPC, telecommunications, data centre, or service provider environment.
- Experience running on-call rosters and incident response.
- Working ability in scripting or programming (e.g., Python, Go, Bash) and infrastructure as code.
- Working knowledge of site reliability engineering practice, including SLOs, error budgets, toil reduction, runbook automation, and production readiness.
- Clear communication and sound judgement, including under pressure.
