Description

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.

Northrop Grumman Space Systems, Multi-Domain Operations, and Missile Defense Integration Business Unit (BU) has an exciting career opportunity for a Mod Sim Systems Engineer / Mission Support Threat Engineer - Level 2 or 3 - to join our team of qualified, diverse individuals. The job location is at Schriever Space Force Base (SSFB), Colorado Springs, Colorado.

Position Overview:

Threat Systems Engineering (TSE) is responsible for the development and delivery of high-fidelity threat modeling products in support of the Missile Defense Agency (MDA) and MDA’s Ballistic Missile Defense System (BMDS). TSE is responsible for the development of Modeling and Simulation (M&S) used to simulate element models of MDA’s BMDS, including kinematic missile modeling, IR signature modeling, data production/analysis activities, and maintenance/sustainment activities for the entire TSE software baseline. TSE is a cornerstone element to the Threat and Advanced Simulations Development (TASD) contract.

The Mod Sim Systems Engineer/Mission Support Threat Engineer role serves as a missile threats specialist, threats model requirements developer, and a verifier and validator of threat representations across the kinematic, RF, and IR signatures domains. This Systems Engineering specialized position will be responsible for capturing and documenting requirements as they pertain to the development of Missiles’ kinematic, RF, and IR signatures models.

The Mod Sim Systems Engineer/Mission Support Threat Engineer will be involved in direct discussions and collaborations with our customers, threat stakeholders, intelligence analysts, and fellow engineers to best capture the requirements for developing and delivering accurate and relevant threat models. Will work with little to no direct supervision, work as an integral member of a product delivery team and meet time-critical delivery schedules. This position will be located on-site at Schriever Space Force Base, in Colorado Springs, CO.

This role requires candidates to be on-site daily with no option for remote/hybrid work.

Essential Functions:

  • Gain experience with threat model phenomenology with focus on components of missile systems trajectories and signatures.
  • Research into RCS and IR signature model development requirements.
  • Understand stakeholders’ requirements and ensure quality production of deliverables.
  • Actively work with the team to ensure automation and tools improvements are coordinated – aiming to attain utmost efficiency and meet Leadership objectives.
  • Work on defined schedule to timely support MDA Ground Test Modeling and Simulation events.
  • Work in close coordination with Missile Modeling Engineers and Production Engineers to ensure model requirements are met and Verification and Validation (V&V) confirm models’ accuracy and reliability.

Seeking candidates who find satisfaction in working on challenging and diverse assignments in collaborative settings across all levels.
