RESPONSIBILTIES
  • Scoping the effort of hosting a single missile model in SysML using existing engineering data analyses with our customers’ subject matter experts. 
  • Creating a scalable workflow for generating new missile models in SysML. 
  • Applying and testing that scalable workflow on a single missile model. 
  • Constructively working with our customers to optimize the SysML model development workflow. 


KEY QUALIFICATIONS
  • Clearance: Top Secret with SCI Eligibility 
  • Education: Bachelor's degree in engineering, science, mathematics or related field. 
  • Years of Experience: 3 to 8 years of experience in systems engineering or related experience. 

  • Proven experience applying model-based systems engineering to aerospace, mechanical or related engineering fields. 
  • Creating MBSE models via the Systems Modeling Language (SysML) or other MBSE tools (e.g., Cameo Systems Modeler, Enterprise Architect, MagicDraw). 
  • Having an MBSE certification and training (e.g. OMG, INCOSE, etc.). 
  • Ability to work with a diverse team of engineers to identify modelling requirements. 
  • Demonstrated conscientious and collaborative work habits to help our customers adopt MBSE for missile performance analyses. 


PREFERRED ADDITIONAL QUALIFICATIONS
  • 5 or more years of experience applying SysML for aerospace engineering applications such as the design of rocket propulsion systems, phased array antenna sensor systems, etc.
