Job Description

Our government customers want assistance with migrating legacy modeling, simulation, and analysis (MS&A) tools, algorithms, applications, and processes pertaining to missile performance analyses into a cloud-native Digital Engineering (DE) pipeline in a phased approach. The primary phase involves creating, updating, and refactoring model-based systems engineering (MBSE) models and libraries representing a full end to-end missile model; the models must be created in SysML. Also, elements of the SysML minimally include requirements (e.g. CEP), structures (e.g. mass moments of inertia), and parametric characteristics (e.g. specific impulse).

Responsibilities

  • 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.

Minimal Qualifications

  • 3 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.

Desired Qualifications

  • 3 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.

Educational Requirements

  • Bachelor’s degree in engineering, science, mathematics or related field.

Clearance Requirements

  • Applicants must have an active TOP SECRET clearance with Sensitive Compartmentalized Information (SCI) eligibility and a CI POLY // TS/SCI CI Poly
  • U.S. Citizenship is required for most positions.
