PLC Controls 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/Division

What You'll Do

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

Do you enjoy solving complex control problems and seeing your designs deployed on real machines? We are seeking an engineer to own the development of machine control and safety systems from concept through deployment. This role includes requirements development, electrical architecture, hardware selection, safety system design, PLC implementation, system integration, validation, and field commissioning. We are looking for engineers who view PLC programming as one part of a complete machine control solution.

As part of KLA's engineering team, you will work with electrical, mechanical, software, systems, and applications engineers to create safe, reliable, and maintainable automation systems for the semiconductor industry. This includes conducting design reviews covering electrical architecture, safety concepts, selected hardware, control implementation, software quality, and developing test strategies, solving system issues, and driving corrective actions that improve product performance and reliability. Successful candidates have experience developing complete systems rather than solely programming PLCs. They understand how electrical hardware, safety systems, industrial networks, instrumentation, software, and mechanical systems interact to produce a robust machine solution.

Through close collaboration with engineers, physicists, software developers, and external suppliers, you will be expected to take ownership of technical challenges, partake in architectural decisions, and help deliver high-quality solutions for critical applications. Occasional cleanroom work is required, along with up to 20% domestic and international travel.

Key responsibilities include:

• Develop machine-level control architectures, electrical designs, and functional safety concepts.
• Define I/O architectures, field device selection, network topologies, power distribution, and control panel requirements.
• Create and maintain electrical schematics, wiring diagrams, control narratives, interface specifications, and design documentation.
• Perform risk assessments and develop safety functions in accordance with ISO 13849-1 and applicable industry standards.
• Evaluate hardware obsolescence and lead replacement strategies for End-of-Life control system components.
• Specify sensors, actuators, pneumatic devices, vacuum systems, motion components, and industrial communication networks.
• Lead system integration, acceptance testing, validation, and commissioning activities. This includes validating system performance through testing, fixing, and root-cause analysis.

Qualifications:

The ideal candidate has experience in the following:

• Developing and implementing medium-to-large scale PLC-based safety and automation systems throughout the product lifecycle.
• Owning controls projects from requirements through commissioning.
• Developing electrical schematics and control system documentation.
• Developing machine safety functions per ISO 13849-1 or IEC 62061.
• Selecting and integrating sensors, actuators, drives, safety devices, and industrial networks.
• Solving issues that may be a combination of electrical, mechanical, controls, and system-level issues.
• Machine control for valves - from pressurized through sub-atmospheric pressures

This position is based in Ann Arbor, Michigan. Remote work is not available.

Additional qualifications include:

Knowledge of industrial networks such as ProfiNet, ProfiSafe, and DeviceNet are very valuable. You need to show a demonstrated ability to deliver reliable solutions with minimal supervision.

Minimum Qualifications

Master's Level Degree and 0 years related work experience; Bachelor's Level Degree and related work experience of 2 years
