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.

Our Systems Engineering Integration & Test (SEIT) organization provides complex subsystems and defense electronics. This position can be hired as either a Systems Engineer, or Principal Systems Engineer, depending on qualifications and years of experience. This position is located at our Rolling Meadows, IL location. This opportunity is available in the Modeling & Simulation discipline in SEIT. Duties and responsibilities can include:

  • Software development of physics-based in-house models and algorithms
  • Perform analysis and trades of product line architectures using analytical models and mission level simulations
  • Functional algorithm development
  • Authoring technical documentation such as white papers, proposal technical volumes, program milestone briefings (i.e. SRR, PDR, CDR,…), systems engineering design documentation
  • Presenting technical analysis to multiple stakeholders
  • Creating and refining Model Based Systems Engineering Products (System behavioral models, Use Case realizations, State Machines, etc.)

In addition, the ideal candidate has recent experience in the fields of either EOIR, RF systems, or both. Specifically, the ideal candidate will have experience in the following specialties.

  • Advanced knowledge and recent experience in one or more of the following areas: EOIR/RF systems: sensors/antennas, transmitters/receivers, lasers, LiDAR, optics, visible and IR cameras, focal plane arrays.
  • Real-time signal processing
  • Requirements analysis and allocation as related to Systems Engineering

As part of the SEIT team, a Modeling & Simulation Engineer is exposed to the full life-cycle of Systems Engineering process and coordinates across many disciplines to ensure that the system is modeled with sufficient fidelity. In the early stages of programs, modeling & simulation is leveraged to understand system CONOPs, inform system architecture, and perform trades. In the later stages as the design matures, field test data is used to verify and validate the models and ensure the payload models are representative of actual performance.

Additional $10k sign-on bonus for selected candidates who possess an ACTIVE TS/SCI clearance, and an additional $5k sign-on bonuses to selected candidates who possess an active Polygraph.

Basic Qualifications:

  • For Systems Engineer, BS degree in Aerospace Engineering, Electrical Engineering, Physics or related technical degree with 2+ years (or MS with 0 years) related experience
  • For Principal Systems Engineer, BS degree in Aerospace Engineering, Electrical Engineering, Physics or related technical degree with 5+ years (or MS with 3+ years, or PhD with 0 years) related experience
