About the Role

We are seeking a VP of Site Reliability Engineering (SRE) to lead Nscale’s global reliability function. You will own the strategy, execution, and leadership of our SRE organisation, ensuring our GPU-accelerated cloud operates with world-class reliability, observability, and operational excellence.

You’ll be responsible for building and scaling SRE teams, defining reliability practices, and driving automation and resilience across infrastructure. This is a high-impact role that will partner closely with Product, Engineering, Infrastructure, and Operations leadership to deliver a secure, performant, and reliable platform at hyperscale.

What you'll be doing

• Define and execute Nscale’s global SRE strategy, aligning reliability goals with business outcomes.
• Build, scale, and lead a world-class SRE organisation, including hiring, mentoring, and developing talent across multiple regions.
• Own service reliability frameworks, including SLOs, SLIs, and error budgets, embedding them into engineering culture.
• Drive the design, automation, and operation of infrastructure platforms across bare-metal, OpenStack, Kubernetes, and Slurm environments.
• Establish best-in-class incident management practices—minimising MTTR and maximising learning from post-mortems.
• Partner with Observability, Infrastructure, and Product teams to deliver 360° visibility across GPU clusters, fabrics, and services.
• Guide capacity planning and scaling strategies, ensuring platform resilience as Nscale expands globally.
• Champion automation-first principles across provisioning, monitoring, CI/CD, and operational workflows.
• Provide executive-level reporting on reliability, operational performance, and capacity to senior leadership.
• Stay ahead of industry trends in SRE, automation, and AIOps, applying them to Nscale’s infrastructure at scale.

About you

• 10+ years of experience in SRE, Infrastructure, or Reliability Engineering, including 3+ years in a leadership role.
• Proven track record building and leading distributed SRE or infrastructure operations teams.
• Deep expertise with Linux systems, Kubernetes, and cloud-native platforms.
• Strong background in bare-metal and datacentre operations, including provisioning (PXE, IPMI), networking, and hardware lifecycle.
• Demonstrated experience in defining and enforcing SLOs/SLIs and error budgets.
• Strong knowledge of automation and Infrastructure-as-Code (Terraform, Ansible, Crossplane).
• Experience driving observability best practices using Prometheus, Grafana, and related tools.
• Skilled communicator with the ability to influence cross-functional teams and report at executive level.

Preferred Qualifications

• Prior experience with OpenStack (OVN networking, KVM virtualization) or HPC environments (Slurm, RDMA, InfiniBand).
• Contributions to open-source communities in SRE, infrastructure, or cloud-native spaces.
• Experience embedding secure and compliant operational practices (SOC2, ISO 27001, GDPR).
• Background scaling infrastructure for AI, GPU workloads, or HPC environments.
