Embedded Software Engineer

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/DivisionThe 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. The RAPID division leads the industry in reticle inspection solutions, helping ensure high lithography yields and cost-effective semiconductor manufacturing. Its systems support both mask shops and fabs by detecting defects early in the process, enabling faster, more reliable production.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.Your Role: Innovate and GrowWe are seeking a highly motivated Embedded Software Engineer to join our team within the RAPID division. In this role, you will take end-to-end technical ownership of embedded software that powers our reticle inspection systems, with a strong focus on high-speed data capture pipelines, and low-level hardware interfaces. You will work hands-on across the stack—from Linux user space to Linux kernel drivers—including PCIe device bring-up and driver development, and you will influence design and implementation direction through strong engineering judgment and design reviews.This is a hands-on, Individual Contributor role. You will drive technical decisions, raise the bar on engineering quality, and collaborate closely with cross-functional teams to deliver reliable, production-grade embedded software.Job Responsibilities:Own Critical Projects & Features: Design, develop, and deploy complex embedded software/firmware for machine control in semiconductor inspection systems. Build demanding quasi real-time applications in C/C++ for image capture systems running on environments such as real-time Linux or VxWorks.Drive Implementation: Design and implement robust, scalable software for system control, high-speed data acquisition, image processing, and intricate hardware interaction. Translate system-level requirements into well-partitioned user-space and kernel-space designs where appropriate.Own Low-Level Interfaces: Develop and debug Linux kernel drivers and related user-space components for custom hardware, including PCIe device enumeration/bring-up, DMA and interrupt handling, memory-mapped I/O, and performance tuning for high-throughput/low-latency data paths.Collaborate Across Boundaries: Partner with mechanical, systems, electrical, optics/opto-mech, algorithms, and applications teams to deliver integrated solutions from concept through production.Raise Team Effectiveness: Share expertise through design reviews, debugging sessions, documentation, and lightweight coaching to help the team deliver consistently high-quality software.Drive Best Practices: Champion modern development practices (Agile, CI/CD, code reviews, automated testing). Define and execute test plans to measure subsystem performance; document, analyze, and present results.Solve Tough Problems: Troubleshoot complex system-level issues across hardware, kernel, and user space; optimize performance-critical software and improve system reliability.Influence the Roadmap: Contribute to technical planning, estimation, and architectural tradeoffs.
