HPC Systems Engineer

Company 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. No laptop, smartphone, wearable device, voice‑controlled gadget, flexible screen, VR device or smart car would have made it into your hands without us. KLA invents systems and solutions for the manufacturing of wafers and reticles, integrated circuits, packaging, printed circuit boards and flat panel displays.

The innovative ideas and devices that are advancing humanity all begin with inspiration, research and development. KLA focuses more than average on innovation and we invest 15% of sales back into R&D. 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 thrive on tackling really hard problems.

There is never a dull moment with us.

With over 40 years of semiconductor process control experience, chipmakers around the globe rely on KLA to ensure that their fabs ramp next‑generation devices to volume production quickly and cost‑effectively. Enabling the movement towards advanced chip design, KLA’s Global Products Group (GPG), which is responsible for creating all of KLA’s metrology and inspection products, is looking for the best and the brightest research scientist, software engineers, application development engineers, and senior product technology process engineers.

Central Engineering is KLA’s largest engineering organization comprised of 9 Centers‑of‑Excellence (CoE) in various disciplines applied across all product groups in the company. These CoE include Handling & Automation, Precision Motion Control, Sensors & Image Acquisition, Platform Design, and Packaging Engineering, among others. Talent includes over 500 engineers across global centers in Israel, China, India, and the US. Each CoE contributes not just talent and deliverables per discipline toward product programs, but also subject matter expertise, best practices, roadmaps, specialized facilities, apparatus, models, and analytics.

These differentiate KLA not only in WHAT we do, but also in HOW we do it.

We’re looking for a HPC Systems Engineer to help power the compute infrastructure behind our R&D innovation! In this role, you’ll support and evolve a high‑performance Linux cluster used for physics modeling, simulation, algorithm development, and machine‑learning workloads—enabling hundreds of engineers to do their best work every day. You’ll play a key role in driving the reliability, performance, and scalability of a shared, mission‑critical HPC environment, partnering closely with infrastructure, Dev Ops, and application teams to keep the platform fast, resilient, and ready for the most demanding computational challenges!

• Operate and maintain a large‑scale Linux based HPC cluster used for internal R&D workloads
• Manage compute nodes, login nodes, and supporting infrastructure in a multi‑tenant environment
• Monitor cluster health, performance, and capacity; respond to incidents and degradations

• Configure, tune, and support HPC job schedulers (e.g., SLURM, LSF, PBS, or equivalent)
• Assist users with job submission issues, resource requests, and queue optimization
• Help optimize scheduler policies to balance throughput, fairness, and utilization

• Install, configure, and maintain Linux operating systems across compute and service nodes
• Manage OS updates, kernel changes, drivers (including GPU drivers where applicable), and system hardening
• Troubleshoot complex Linux performance, networking, storage, and process level issues

• Support high throughput and parallel workloads across CPU and GPU resources
• Diagnose performance bottlenecks across compute, storage, network, and scheduler layers
• Assist with scaling activities such as node expansions, re provisioning, and hardware refreshes
