At Northrop Grumman, our employees have incredible opportunities to work on revolutionary systems that impact people's lives around the world today, and for generations to come. Our pioneering and inventive spirit has enabled us to be at the forefront of many technological advancements in our nation's history - from the first flight across the Atlantic Ocean, to stealth bombers, to landing on the moon. We look for people who have bold new ideas, courage and a pioneering spirit to join forces to invent the future, and have fun along the way. Our culture thrives on intellectual curiosity, cognitive diversity and bringing your whole self to work — and we have an insatiable drive to do what others think is impossible. Our employees are not only part of history, they're making history.
We are looking for a Principal Modeling Simulation and Analysis Engineer or Senior Principal Modeling Simulation & Performance Analysis Systems Engineer to join our team in Baltimore, MD. This position requires 100% on-site work.
What You Will Get to Do:
As an integral member of the Modeling, Simulation and Analysis Section and the broader Systems Engineering team, you will accelerate delivery of capabilities to our customers through performance engineering, software integration, and test activities that leverage credible modeling, simulation, experimentation, and analysis. You will apply MS&A techniques with a focus on systems and software performance analysis across all phases of radar systems engineering to assess, validate, and optimize system and subsystem performance, interacting with IQ data from simulated and real-world collections, following it through the radar processing chain, and working closely with M&S and radar mode teams to identify and resolve deficiencies in both modeled data and operational modes.
Perform performance-focused modeling and simulation on high-performance computing grids to evaluate and optimize system and subsystem behavior, conduct trade studies, and generate systems engineering documents, reports, and operational documentation.
Utilize Modeling, Simulation, Experimentation, and Analysis (MSE&A) frameworks to support software integration, algorithm development, and radar mode validation, ensuring consistency between modeled environments and real-world data.
Assess system capabilities by linking system and subsystem requirements to performance metrics and mission threads, defining and verifying interfaces and their connections that enable mission execution, and supporting integration and test activities during development.
Support systems engineering radar algorithm validation by tracing IQ data through the radar processing chain, comparing modeled and collected data, and identifying performance shortfalls and corrective actions.
Plan, generate, and execute verification and validation artifacts supporting system design verification testing and system acceptance testing, including test plans, procedures, and data review packages.
Develop and improve performance models, simulation frameworks, and analysis tools, including physics-based radar models, threat and environment models, and command-and-control interactions, to accurately represent system behavior under varied conditions.
Perform large-scale data analytics, probabilities, and statistics, including the application of design of experiments techniques for the evaluation of system and mission performance, algorithm robustness, and sensitivity to key parameters.
Collaborate with interdisciplinary teams (M&S, software, radar modes, systems integration & test) to diagnose performance issues, recommend design changes or tuning, and ensure integrated solutions meet performance requirements.
Generate and present technical material to support internal and external customer briefings, technical reviews, and design/test readiness events.
Innovate to solve problems and identify improvements across MSE&A products, performance analysis workflows, and integration/test approaches.
Develops, integrates, and uses advanced graphical user interfaces and visualization tools to explore, validate, and communicate performance results.
