Profile match
Headquartered in Chantilly, Virginia, Space Systems Integration (SSI) is an engineering consultancy that provides technical expertise and systems engineering services to the aerospace, intelligence, and defense sectors. The company specializes in spacecraft mission design, subsystem engineering, acquisition strategy, and detailed analytical trade studies for space programs. Additionally, it offers proprietary trajectory and attitude visualization software, project management, and proposal support to assist clients throughout the lifecycle of complex satellite missions.

SSI is seeking a Multi-Domain Sensing Engineer/Model Simulation Analyst for a role in Colorado Springs, CO.

This position requires significant technical understanding of MW/MT as well as significant experience with M&S. The candidate must be able to: articulate what missile warning and tracking sensing is needed from tactical to strategic levels, where it needs to go and how fast it needs to get there; employ and develop modeling, simulation, and analysis tools; analyze modeling and simulation results; coordinate internal and external modeling and simulation efforts and provide recommendations on potential improvements to concepts and architectures.

Role and Responsibilities include:

  • Develop target (missile) and effector simulations and corresponding trajectory and behavior files using industry standard M&S tools such as the Advanced Framework for Simulation Integration and Modeling (AFSIM).
  • Develop modeling and simulation analysis and assessment scripts using government network supportable tools such as Python, and/or Matlab.
  • Develop space-based missile warning access and performance models using industry standard M&S tools such as Systems Tool Kit (STK) or Satellite Orbit Analysis Program (SOAP) and integrate SWAC space-based ISR capability area force designs with modeling and simulation expertise.
  • Assist in force design analysis planning, analysis execution coordination, and analysis results evaluation.
  • Recommend and document force design dependencies and opportunities (joint, intelligence community, industry, international and other government organizations).
  • Assist with modeling inputs and simulation development for external M&S efforts.
  • Collaborate in cross-functional planning, coordination and task execution involving the full spectrum of systems engineering and integration activities for a force design effort.
  • Coordinate efforts internally and externally with multiple agencies/organizations.

Required Qualifications:

  • Min. 10 years of experience with BS degree, 8 years with Masters degree.
  • Demonstrated experience developing complex space system models and simulations in AFSIM is a must. Additional experience with industry standard tools such as STK and/or SOAP is highly desired.
  • Demonstrated experience developing simulation scripts and interface code using government supportable software languages such as Python, and/or Matlab.
  • 5+ years of space system modeling and simulation experience including analyzing modeling and simulation results.
  • In depth understanding of MW/MT systems and operations.
  • STEM bachelor’s degree (master’s preferred).
  • Strong communication skills.
  • Ability to understand complex technical issues and produce recommendations for a wide audience.
  • Have a background of applying analytical problem solving at the tactical, operational and strategic levels of war across multiple DoD organizations.
  • Ability to apply a variety of analysis techniques to identify operational shortfalls of U.S. space capabilities and concepts and make recommendations for future architectures.
  • Ability to quickly create decision-quality materials for senior leaders.
  • Ability to apply critical thinking in complex and dynamic organizational environments.
  • Experience with space design, architecture, and/or system development (desired).
  • Knowledge of how to work in a classified and compartmented working environment is required.
  • Active TS clearance with in-scope T5/SSBI is required, along with SCI eligibility and participation in Continuous Evaluation.
  • Current polygraph (within 5 years) is desired.
  • Must meet all requirements for SCI and SAP access and be willing to undergo a polygraph examination.
  • Travel is 10%.
