Job Description/Preferred Qualifications

Key Responsibilities

HPC Software Engineering

· Design, develop, and optimize HPC software running on large-scale Linux clusters, including distributed and parallel workloads (MPI, multithreading, GPU-accelerated pipelines, containerized workloads).

· Optimize application performance and power utilization across CPU, memory, storage, and network subsystem, with attention to throughput, latency, and scaling behavior.

· Develop and maintain system-level tooling for cluster bring-up, diagnostics, monitoring including component power usages, and health checks.

· Work closely with algorithms, systems and application teams to understand and translate workload characteristics into power-efficient HPC software solutions.

HPC Systems & Hardware Awareness

· Collaborate with hardware and systems teams to define HPC node, storage, and interconnect requirements based on software and algorithm needs.

· Understand and influence CPU/GPU selection, memory sizing, PCIe layout, NUMA behavior, and network topology to ensure optimal software performance.

· Participate in HW/SW co-debug activities, including performance bottlenecks, stability issues, and failure analysis.

Rack & Infrastructure Engineering

· Understand rack-level integration of HPC systems, focusing on power, cooling, cabling, networking, and physical layout considerations.

· Understand data-center and lab constraints such as power budgets, thermal limits, network drops, and serviceability.

· Contribute to best practices, and design reviews for new platforms and refresh cycles.

Cross-Functional Collaboration

· Act as a technical bridge between software, hardware, systems teams.

· Provide clear technical documentation covering software and system architecture, deployment flows, performance assumptions.

Required Qualifications

· Bachelor’s or Master’s degree in Computer Science, Computer Engineering, Electrical Engineering, or equivalent practical experience.

· Strong experience developing HPC or systems software on Linux.

· Proficiency in Java and/or C++ and/or other system-level or performance-oriented languages.

· Hands-on experience with parallel computing (MPI, OpenMP, multithreading). Candidates with GPU computing (CUDA, ROCm, or equivalent) would be preferred.

· Solid understanding of HPC hardware fundamentals: CPUs, memory hierarchies, storage, networking (Ethernet / InfiniBand).

· Practical experience working with clusters, servers, or rack-scale systems in lab or production environments.

· Strong debugging skills across software, OS, and hardware boundaries.

Preferred Qualifications

· Experience with containerized HPC environments (Docker, Singularity/Apptainer, Kubernetes in HPC contexts).

· Familiarity with high-speed interconnects, storage architectures, and performance benchmarking.

· Exposure to rack integration, including cabling, power distribution, cooling, and system bring-up.

· Experience in semiconductor, manufacturing, or high-reliability systems environments.

· Ability to reason about system reliability, MTBF/MTBA, and failure modes in large compute installations.

What Makes This Role Unique at KLA

· Work on mission-critical HPC platforms that directly impact semiconductor manufacturing capability.

· Influence both software architecture and physical system design, not just code in isolation.

· Collaborate with world-class experts across algorithms, hardware, systems, and operations.

· See your work deployed at scale in real production tools—not just in the data center.
