This role places you in a program office where you will support and manage established modeling and simulation activities as well as contribute direct, hands-on simulation support as a member of a fast-paced multidisciplinary mission operations modeling, simulation, and analysis team.

Your knowledge and background will guide the programs and in-house team’s modeling and simulation activities, assembling and releasing various analysis simulations and trade studies, placing you at the forefront of novel and burgeoning technology development and ultimately helping the Government navigate complex system acquisition throughout the full lifecycle of developmental programs. Join us and help the warfighter realize their needs!

The responsibilities for this position include:

Design, develop and, or verify simulations and analysis plans, as well as other work products such as gap analyses or Technical Performance Measures (TPM) assessments that enable key program and architectural decisions
Generate analytical modeling solutions to assess system/system-of-systems performance and other related performance parameters

Identify needs and opportunities for independent assessment and improvement of the system and, or system-of-systems/family-of-systems
Incorporate system models into existing, enterprise models that demonstrate integration into the find, fix, target, track, engage, and assess chain using relevant, related sensor, effects, and communications technologies
Support analysis activities by integrating performance models with MBSE models and tools
Quantify performance impacts and sensitivity to changes in CONOPS, scenarios, and/or threats
Strong communications skills and the ability to prepare and deliver briefings that cover technical and programmatic subjects to uniformed Space Force and government civilian personnel
Knowledge and experience with Space Force capabilities, systems, and enterprise architecture elements

This is you:
