nLIGHT-DEFENSE Systems, Inc. is one of the nation's leading developers of Directed Energy systems, which is a top modernization priority of the Department of Defense. Our High Energy Laser (HEL) systems, Adaptive Optical (AO) systems, and Acquisition / Pointing / Tracking (APT) solutions are designed to overcome the most difficult challenges facing the deployment of high energy laser solutions to the United States military and our allies.

Located in Longmont, Colorado, nLIGHT-DEFENSE Systems, Inc. is a vertically integrated business that leverages internal capabilities - from semiconductor device through target identification - to develop systems that are both high-performance and cost-effective. We continue to invest in capabilities, facilities and technology to bring leading edge HEL solutions to the warfighter. This is a great opportunity to work at a company that is on the leading edge of the HEL industry and provides a culture of excellence and commitment to delivering solutions to the warfighter and our country.

Headquartered in Camas, Washington, nLIGHT is a publicly listed company (NASDAQ: LASR).

The Sr. Controls Engineer plays a critical role in defining, modeling, and refining the control systems that enable reliable HADES product performance during threat engagements. This role develops full system models to understand capability, predict behavior, and guide design decisions across the product line. The controls team owns the broader controls architecture-from component level loops to full system control-across frequency domains ranging from 10 Hz to MHz.

As a handson technical subject matter expert, the Sr. Controls Engineer collaborates with mission modeling, software, firmware, and hardware teams to translate system level requirements into practical control solutions. They evaluate stability and performance margins, improve control strategies, and ensure alignment between system models, control implementations, and physical hardware. A key responsibility is correlating model predictions with measured hardware behavior to identify gaps, improve fidelity, and accelerate technical improvements.

Success in this role is demonstrated through stable, robust engagement performance; trusted full system Simulink models; and control architectures that can be effectively implemented, tested, and evolved with cross functional partners.

All applicants must possess or be qualified to obtain a U.S. DoD Personnel Security Clearance. Preference will be given to candidates with an existing U.S. DoD Personnel Security Clearance.
