Senior Software Engineer, Architecture & Algorithms

To make electronics, you need chips, wafers, transistors, reticles, and... To make these, you must see, test and manufacture them at scale—faster and better than ever before. That's where KLA comes in. Whether you're early in your career or an experienced professional, you'll solve complex challenges, work alongside brilliant minds and help shape the future of technology.

Group/Division The Semiconductor Products and Customers (Semi PC) business unit designs, builds and sells KLA’s product portfolio to help chip manufacturers meet high-quality standards for technologies like AI, data centers, automotive and electronic devices. Our inspection, metrology, and analytics systems detect and monitor defects across logic and memory chips, specialty semiconductors, wafers, reticles, advanced packaging, process equipment and materials. We also develop technologies for specialty processes, IC substrates, and PCB manufacturing, including etch and deposition, component inspection, and imaging and analytics.

KLA Instruments is our instrumentation division, which designs advanced metrology and inspection instruments used in both R&D and production across industries and academia. Our tools—ranging from optical profilers and nano-indenters to thin film and defect inspection systems—enable precise surface and material analysis. We partner closely with customers to enable R&D, improve yield, optimize processes, and reduce production costs through innovative hardware, software and application expertise.

What You'll DoIn this role, you will play a key part in advancing business priorities by delivering high-impact work across your area of expertise.

As a Senior Software Engineer focused on architecture and algorithms, you will define the software architecture and design the core measurement, data-analysis, and signal/image-processing algorithms that power our families of surface profiler, thin film, sheet resistance and nanoindentation measurement instruments, leveraging cutting-edge technologies and the latest advancements in software engineering and AI/ML/DL.Responsibilities:

Deliver well-defined features/components with high-level guidance: estimate work, communicate risks/tradeoffs, and deliver on schedule

Own and evolve the software architecture across the development lifecycle—defining system- and subsystem-level requirements, interfaces, and specifications, and guiding key design decisions

Design, implement, and optimize core algorithms for measurement, data analysis, and signal/image processing, including numerical methods and high-performance multithreaded code Develop C#/.NET and C++ software for data analysis and algorithm implementation; write maintainable, well-structured code and use AI-assisted tools responsibly under company security policies

Evaluate and compare algorithmic approaches through prototyping, benchmarking, and analysis of accuracy, precision, and computational complexity

Build robust unit/integration tests and use profiling to improve algorithm performance, accuracy, memory usage, reliability, and security

Participate in design reviews and incorporate feedback from stakeholders and subject matter experts

Troubleshoot system/subsystem issues using logs and experiments; contribute to root-cause analysis, implement fixes with guidance, and help prevent recurrence

Demonstrate motivation to independently learn and apply new software technologies

Travel - Occasional travel may be required to KLA headquarters, customer sites, or other business locations. Travel is expected to be less than 10% of working time.
