Northrop Grumman Defense Systems is seeking a Principal / Sr. Principal Controls Engineer – Systems Signal Architecture & Controller Integration. This position is located in Roy, UT supporting the Sentinel program. What You’ll Do: You will join the Sentinel Launch Systems Infrastructure team as a controls engineer focused on systems signal architecture and controller operations for both COTS controllers and custom hardware. In this role, you will define and integrate control system signal architectures, select and configure controllers, and ensure robust, testable interfaces across facility, launch, and mission equipment subsystems. The ideal candidate understands how weapon system and facility requirements drive control system behavior, and can translate those needs into controller configurations, I/O mappings, communication networks, and testable requirements. You will work closely with electrical, systems, software, and test engineering to deliver safe, reliable, and maintainable control solutions. Controls & Signal Architecture Ownership Develop and maintain the end to end signal architecture for assigned systems, including I/O lists, signal types, addressing, and routing. Ensure clean segregation of safety critical, mission critical, and non critical signals. Controller Integration (COTS & Custom) Specify, configure, and integrate COTS controllers (e.g., PLCs, PACs, motion controllers, data acquisition hardware) and custom control hardware. Implement control logic, I/O mapping, and fault handling to meet system performance and safety requirements. Requirements & Interface Definition Translate system level requirements into control system and signal level requirements. Develop interface control documents (ICDs), control narratives, and sequence of operations to align hardware, software, and facility teams. Modeling, Simulation & Analysis Use analytical tools and models (e.g., MATLAB/Simulink, similar platforms) to evaluate control strategies, timing, and performance. Support trade studies to select architectures, networks, and controller technologies. Test, Verification & Troubleshooting Develop and execute test plans, procedures, and automated test sequences for controller hardware and software. Support integration labs, hardware in the loop (HIL) setups, and field test activities, including root cause analysis (RCA) for control system anomalies. Cross Functional Collaboration Work closely with electrical power, facility, mechanical, software, and systems engineering to ensure controls solutions align with power distribution, instrumentation, and mechanical actuation. Coordinate changes and maintain configuration control of control system artifacts. Documentation & Configuration Management Create and maintain engineering documentation including control schematics, signal lists, controller configuration baselines, test procedures, and as built updates. Ensure all artifacts meet program, customer, and configuration management requirements. Continuous Improvement & Support Identify
