Senior Software Engineer, Architecture & Algorithms

• 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.

• Bachelor's degree (required) + Significant relevant experience; Master's or advanced degree (desired).
• Relevant experience in Computer Science, Software, Electrical, Industrial, or Manufacturing Engineering, Physics, or Mathematics.
• A solid understanding and demonstrated track record in the practice of software engineering fundamentals, including software architecture, data structures, algorithms, design patterns, event driven design, multithreaded design, testing, and debugging.
• Strong foundation in algorithms and numerical methods, with the ability to design, analyze, and optimize algorithms for accuracy and performance.
• Experience with Microsoft .NET languages including VB.NET and C#; C++ programming; Microsoft Visual Studio development environment; source code control systems such as Git; adherence to software design and coding standards.
• Ability to communicate effectively with peers, interdisciplinary engineering groups, customers, and suppliers, including delivering clear technical presentations.
• Adept at collaborating with teams across the US, Europe, and Asia.
• Self driven individual with strong technical ability, a systematic approach, and excellent problem solving skills.

• Experience contributing to architecture and design for complex subsystems and influencing technical decisions through strong design and code reviews.
• Experience developing scientific, measurement, or signal/image processing algorithms.
• Background in applied mathematics, numerical methods, statistics, or scientific computing.
• Experience improving performance and diagnostics/observability for system level software.
• Experience collaborating across teams on system integration and software releases for complex systems.
• Experience delivering AI/ML capabilities in products.
• UX skills including wireframing, prototyping, and user flow design.

• Annual leave starting at 25 days (plus bank holidays).
