Senior Firmware & Software Engineer

Responsibilities

• Deliver well-defined features/components with high-level guidance: estimate work, communicate risks/tradeoffs, and deliver on schedule
• Collaborate cross-functionally across the development lifecycle to define architecture and create system- and subsystem-level requirements/specifications
• Design, implement, and debug embedded firmware (C/C++) for microcontrollers and real-time control of instrument hardware, including communication interfaces such as USB, Ethernet, serial/UART, SPI, and I2C
• Develop Windows desktop software in C#/.NET (WPF/WinForms) and C++ for instrument control, GUI, and data analysis; write maintainable, multithreaded code and use AI-assisted tools responsibly under company security policies
• Partner closely with electrical and hardware engineers on board bring-up, signal and schematic debugging, and firmware/hardware co-development using oscilloscopes, logic analyzers, and in-circuit debuggers
• Build robust unit/integration tests and use profiling to improve performance, 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.

Requirements

• A solid understanding and demonstrated track record in the practice of software engineering fundamentals, including architecture, data structures, design patterns, event-driven design, multithreaded and real-time design, testing, and debugging.
• Experience with: Microsoft .NET and C# for Windows desktop application development (WPF and/or WinForms)
• C and C++ programming, including embedded firmware development
• Embedded systems and microcontroller firmware, including real-time control and hardware communication protocols (USB, serial/UART, SPI, I2C)
• Interfacing software and firmware with electronic hardware, and using lab instruments such as oscilloscopes and logic analyzers for debugging
• Microsoft Visual Studio development environment
• Source code control systems such as Git
• Adherence to software design and coding standards
• Working knowledge of electronics with the ability to read schematics and component datasheets and collaborate effectively with electrical and hardware engineering teams
• 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
• Preferred:
• Experience contributing to architecture and design for complex subsystems and influencing technical decisions through strong design and code reviews
• Experience improving performance and diagnostics/observability for system-level software
• Experience with RTOS, bare-metal firmware, device drivers, and low-level debugging
• Fa
