Northrop Grumman Space Systems, Multi-Domain Operations, and Missile Defense Integration Business Unit (BU) has an exciting career opportunity for a Modeling & Simulation Systems Engineer – Level 1 or 2 (IR Plume Mod/Sim Systems Engineer) to join our team of qualified, diverse individuals. This position will be located on-site at Schriever Space Force Base, in Colorado Springs, CO.

This role requires employees to be onsite daily with no option for remote/hybrid work.

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 models and simulations (M&S) used to stimulate 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.

Essential Functions

• Data Engineering and Validation
  • Handling large-scale, multi-dimensional array datasets
  • Validating simulated data against measured test or flight data
• Analytical Rigor
  • A natural tendency toward thoroughness and attention to detail
  • Meticulous verification and validation of large, technical datasets
• Troubleshooting and Diagnostics
  • Systematic Root-Cause Analysis: Ability to logically isolate variables and trace errors to determine if a simulation failure is caused by bad input data, software bugs, or system configuration issues.
  • Legacy & Custom Code Debugging: Skilled at reading, parsing, and fixing errors in undocumented, in-house tools or legacy scripts (e.g., Python, MATLAB, C++) without relying on external support or documentation.
  • Log Parsing & Error Identification: Proficient at reading complex log files, console outputs, and stack traces to quickly pinpoint why a simulation run or data conversion tool crashed.
  • Data Sanity and “Silent Error” Detection: Able to identify and fix “silent failures” – where a tool runs to completion but produces physically or mathematically incorrect data.
• Team Collaboration
  • Excellent verbal and written communication skills.
  • Ability to prioritize and execute tasks and enjoy working in a collaborative team environment.
  • Ability to create and work within schedules and timelines

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