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). Summary: 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 fullsystem models to understand capability, predict behavior, and guide design decisions across the product line. The controls team owns the broader controls architecture-from componentlevel loops to fullsystem 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 systemlevel 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 fullsystem Simulink models; and control architectures that can be effectively implemented, tested, and evolved with crossfunctional 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.Further information on requirements to obtain a security clearance is available at:**https://www.dcsa.mil/mc/pv/mbi/gicp/**.Please review this information before applying. Responsibilities: - Develop and maintain fullsystem Simulink models to understand HADES capability, predict behavior, and guide controlsystem design decisions. - Correlate models with hardware test data to improve fidelity, identify technical risks, and assess performance across operating conditions. - Define and refine controls architecture spanning componentlevel loops through fullsystem control across broad frequency domains. - Develop robust control strategies and translate systemlevel requirements into implementable control algorithms. - Lead controlsfocused hardware integration, debugging, commissioning, and tuning in laboratory and representative test environments. - Verify stable, responsive, and robust control performance during integrated system operation and engagements. - Partner with mission modeling, software, firmware, and hardware teams to ensure models, embedded controls, and physical hard are work together as intended. - Communicate technical risks, test results, and design tradeoffs clearly to drive informed decisions. Required Experience / Capability: - Commitment to Excellence, Attention to Detail, and Pride in Workmanship. - Ability to work effectively in a dynamic environment and maintain strong working relationships under pressure. - Ability to execute independently and lead technical efforts in support of program milestones. - Demonstrated proficiency designing, analyzing, and tuning robust feedback control systems, including stability and performancemargin evaluation. - Ability to develop systemlevel models, use simulation to guide design decisions, and correlate model results with hardware test data. - Proficiency in MATLAB, Python, or C#. - Handson experience integrating, tuning, and troubleshooting control systems on physical hardware. - Strong communication skills with the ability to convey technical results, risks, and tradeoffs across crossfunctional teams. Desired Experience / Capability: - Advanced knowledge of estimation, sensor fusion, observer design, system identification, or signal processing. - Experience using measured system data for plant modeling, system identification, and modeltohardware correlation. - Knowledge of robust, stochastic, nonlinear, or adaptive control methods. - Experience modeling or analyzing cascaded, asynchronous, distributed, or networked control systems. - Proficiency in Simulink for system modeling, simulation, verification, and controlsystem design. - Familiarity with realtime embedded implementation (C++, CUDA, FPGA development, or HDL). - Background in robotics, path planning, attitude determination, or related GNC applications. - Experience with HIL/SIL or other modelbased verification approaches. - Experience with adaptive optics, optomechanical systems, electrooptical systems, or precision beamcontrol architectures.
