Senior Site Reliability Engineer

Take end-to-end ownership of production GPU clusters for training and inference across AWS and OCI, keeping them highly available and performant.

Join critical re-architecture sessions to redesign systems for higher efficiency and scale.

Tune Linux performance deeply, at the OS and kernel level.

Build automation in Python, Go, or Bash to manage, monitor, and self-heal infrastructure without heavy toil.

Serve as the final escalation for the hardest GPU, networking (InfiniBand/RDMA), and system failures, working with vendors like NVIDIA.

Help achieve and maintain security certifications (SOC 2 Type 1 & 2, ISO) with strong infrastructure security practices.

One way the first 90 could unfold.

Days 1–30 — Immerse & Diagnose: Learn the current clusters across on-prem, AWS, and OCI, and where reliability and performance hurt most.

Days 30–60 — Ship & Validate: Take ownership of a production cluster and ship automation or tuning that measurably improves availability or performance.

Days 60–90 — Scale & Systemize: Contribute to the next-gen re-architecture and harden security and compliance practices.

5+ years as an SRE, production, or infrastructure engineer in a fast-paced, large-scale environment.

Deep, hands-on Linux expertise, containerized systems, and low-level performance debugging.

Working experience with Terraform, Airflow, and Ray.

Strong experience with AWS or OCI.

Practical experience with high-performance networking (InfiniBand, RDMA, or RoCE).

Working knowledge of security best practices and compliance frameworks like SOC 2 and ISO.

Comfort in a less-structured, fast-paced environment.

Deep expertise with GPU tooling for NVIDIA and AMD (DCGM, ROCm).

Experience managing large-scale GPU clusters for AI/ML training or inference.

Familiarity with Kubernetes or orchestration frameworks like Ray.

Deep expertise in data pipelines and infrastructure.
