Control Systems Engineer; PLC Specialist

Position: Control Systems Engineer (PLC Specialist)
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's Central Engineering organization is made up of nine Centers of Excellence (CoEs) spanning disciplines like automation, motion control, sensors, platform design, and packaging. Each CoE contributes not only technical deliverables but also deep expertise, best practices, and advanced tools that elevate both what we build—and how we build it.

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.

We are looking for an Electrical Control Systems Engineer with in-depth expertise in PLC programming, particularly across platforms such as Allen-Bradley and Siemens. In this role, you will design complex PLC logic to automate and control systems, design schematics for control system (i.e. PLC I/O wiring, etc.),  while also developing intuitive HMI (Human-Machine Interface) solutions to enhance operator usability. You will be responsible for PID control loops circuit design whether for precise temperature control, motion systems, or other process feedback, ensuring stable closed or cascade loops including PID tunning and configurations.

You’ll work across the full project lifecycle: from gathering requirements, initial concept and detail design, integration, and implementation to commissioning and ongoing optimization. Familiarity with FPGA technology, microcontrollers (such as ARM or AVR), or DSPs will be beneficial as you contribute to diverse control architectures. In this role, you’ll ensure our control systems are robust, efficient, and seamlessly integrated into the overall solution.

Additional Responsibilities Conceptual and detailed design using design tools (i.e. OrCAD, AutoCAD, PSpice, Xilinx/Altera FPGA / EPLD development system, etc.), also firmware development using Siemens, Allen Bradley PLCS, etc.

Testing and data analysis using tools (i.e. MATLAB, Python, etc.), detailed drawings, design review presentations, procurement of prototype parts, system integration, prototype testing, and handoff to manufacturing.

Collaborates with mechanical, software, systems and manufacturing engineers to ensure seamless integration and test at the subsystem and system level.

Develops the required supporting documentation, such as assembly and test procedures, and service manuals.

Partners with suppliers to ensure all design requirements are specified and achieved.

Addresses and resolves product issues thru the product phases.

Leads and oversees projects from initiation to completion.

Qualifications Bachelor’s degree, or higher, in Electrical Engineering   Electrical engineering background

Basic electrical circuit design with design tools such as OrCAD, AutoCAD, PSpice, Xilinx/Altera FPGA /EPLD or development systemPLC…
