Senior Site Reliability Engineer / HPC - Pre-IPO Tech Leader

We are seeking a highly skilled Senior Site Reliability Engineer (SRE) / High-Performance Computing (HPC) Engineer to design, build, and operate the large-scale infrastructure that powers a $2.5B pre-IPO technology company. Our systems run on massive distributed clusters, handling some of the most demanding workloads in cloud, AI, and data-driven computing.

In this role, you will be responsible for ensuring the reliability, scalability, and performance of mission-critical platforms. You will optimize HPC workloads, streamline CI / CD for large-scale clusters, and enable research and product teams to deliver innovations with speed and confidence. This is a hands-on position with the opportunity to influence architecture, lead reliability initiatives, and solve some of the hardest problems in distributed systems and performance engineering.

What You'll Do

• Design Reliable Infrastructure : Architect and maintain large-scale, distributed HPC and cloud-native systems with a focus on uptime, scalability, and resilience.
• Optimize HPC Workloads : Tune scheduling, job orchestration, and performance for compute- and memory-intensive workloads (AI / ML, simulations, large-scale analytics).
• Build Observability : Implement monitoring, logging, and alerting systems that provide full visibility into cluster and service health.
• Automate Everything : Develop tooling and automation for provisioning, scaling, and recovery of critical systems.
• Ensure Security & Compliance : Implement best practices for access control, encryption, and governance across HPC and cloud environments.
• Collaborate Cross-Functionally : Work with engineering, research, and product teams to deliver reliable infrastructure for next-gen applications.
• Incident Response : Lead troubleshooting, root cause analysis, and postmortems for high-severity incidents.

What We're Looking For

This is an opportunity to join a pre-IPO technology leader valued at $2.5B, at a time of rapid growth and innovation. As a Senior SRE / HPC Engineer, you will shape the infrastructure that powers next-generation AI, analytics, and large-scale computing.
