Director, Site Reliability Engineering — AI Accelerator Infrastructure

The Role

You will build and lead Our Client's Site Reliability Engineering function from the ground up — owning the infrastructure that development, validation, and customer-facing deployments run on. This spans colocation facilities, on-premises lab clusters, cloud environments (AWS, Azure, GCP), and the platform services customers use to collaborate with our Client on hardware and software deployments.

You are a hands-on engineering leader. You will establish SRE as a discipline at our client, hire and grow the team, set the technical direction, own SLOs for critical systems, and be the senior escalation point when things go wrong — all in parallel. You will partner closely with the Director of DevOps Engineering, whose pipelines and automation run on the infrastructure you own, and work directly with hardware and software development teams to ensure HPC infrastructure meets their workload requirements.

### What You Will Do

Leadership & Organizational Build-Out

• Own the SRE function end-to-end: define the team's charter, establish SRE as a discipline within our client's engineering culture, and drive buy-in across hardware, software, and executive stakeholders who have operated without a dedicated SRE team.
• Hire, develop, and retain a team of 3–5 SRE engineers; establish a culture of operational excellence, ownership, and continuous improvement from day one.
• Define the SRE technical roadmap: reliability architecture, automation priorities, capacity planning, and on-call model — and execute against it with your hands on the keyboard where needed.
• Serve as the senior technical escalation for critical incidents — guiding cross-team triage, driving RCA, and ensuring systemic fixes rather than point patches.
• Translate operational signals and infrastructure health into clear, actionable narratives for engineering leadership and executive stakeholders.
• Partner with the Director of DevOps Engineering to align infrastructure rel...
