Sr. HPC Systems Architect; Linux

Overview

KLA is a global leader in diversified electronics for the semiconductor manufacturing ecosystem. Virtually every electronic device in the world is produced using our technologies. KLA invents systems and solutions for the manufacturing of wafers and reticles, integrated circuits, packaging, printed circuit boards and flat panel displays. Our expert teams of physicists, engineers, data scientists and problem-solvers work together with the world’s leading technology providers to accelerate the delivery of tomorrow’s electronic devices.

Life here is exciting and our teams tackle hard problems. This description retains the primary focus on the role and its responsibilities within the company’s technology ecosystem.

This role provides senior technical leadership for the architecture, deployment, and long-term scalability of large-scale HPC storage and compute platforms. It owns systems end-to-end—from early architectural definition through full production—partnering across engineering, manufacturing, and strategic vendors to deliver highly available, high-performance infrastructure  scope emphasizes deep technical ownership, architectural decision-making, and solving sophisticated infrastructure challenges in live production environments. This work directly develops critically important HPC platforms built for adaptability, scale, and operational excellence, driving real-world impact across core products and technologies.

• Lead the design, implementation, and ongoing support of high-performance compute (HPC) clusters, taking accountability for system performance, reliability, and scalability
• Serve as a technical authority for HPC storage, with deep hands-on expertise in parallel file systems such as Lustre, GPFS, and BeeGFS
• Apply sophisticated systems knowledge across CPU and GPU architectures, high-bandwidth interconnects, and robust storage subsystems to deliver balanced, high-performance solutions
• Lead the creation of hardware BOMs for HPC clusters, working directly with vendors and coordinating hardware release activities
• Design, configure, and optimize Linux operating systems for HPC environments
• Translate project specifications and performance requirements into subsystem and system-level designs, driving execution while meeting technical and schedule commitments
• Support the design, release, and transition of new systems to manufacturing and customers, providing high-quality golden images, procedures, scripts, and documentation
• Lead EOL part re-qualification activities to ensure long-term system viability and supportability

• Proven experience with HPC systems and Linux platform
• Strong, distro-agnostic Linux experience (Rocky, RHEL, SuSE, Ubuntu)
• Strong scripting skills in Shell and Python
• Strong understanding of HPC hardware platforms (servers, GPUs, networking, storage, BIOS/BMC)
• Advanced Linux systems knowledge (PXE/netboot, systemd, HA concepts)
• Solid networking fundamentals (TCP/IP, DNS, DHCP, LDAP, HTTP)
• Experience with configuration management and automation (Salt, Ansible, Puppet, Chef, etc.)
• Interest in HPC storage

• Strong Dev Ops and automation mentality (CI/CD pipelines, Git, infrastructure as code)
• Experience with containers for HPC (Singularity, Docker)
• Monitoring and observability experience (Prometheus, Grafana)
• Familiarity with Apache/Nginx and supporting infrastructure services

Requires minimum of 8 years of related experience with a Bachelor's degree; or 6 years and a Master's degree; or a PhD with 3 years experience; or equivalent experience.
