- Simulation architecture - Ability to design and validate simulation architectures and system-level integrations.
- Digital twins & digital threads - Experience creating and evolving digital twins for mission systems.
- Interface design & simulation - Ability to model and simulate system and subsystem interfaces.
- Numerical methods - Knowledge of integration methods, control theory, estimation, orbital mechanics, or multi-domain modeling.
- Verification & validation - Experience with virtual integration and V&V of simulation components.
- Performance evaluation - Ability to define and assess simulation-based performance metrics.
- Cross-functional collaboration - Ability to work with systems, software, mission analysis, and UI/UX teams.
- Technical communication - Skilled in presenting simulation results and design artifacts.
Desired Skills - High-fidelity simulation tools - STK, GMAT, Orekit, Trick, Modelica, or similar frameworks.
- Real-time & HIL simulation - Experience with real-time or hardware-in-the-loop environments.
- HPC & GPU-accelerated workflows - Familiarity with CUDA, Vulkan compute, OpenCL, or HPC pipelines.
- Graph-based data modeling - Knowledge of metadata lineage and digital-thread integration.
- API integration - Experience integrating simulation engines with REST, gRPC, or GraphQL APIs.
- Simulation visualization - Experience with Three.js, WebGL, React Three Fiber, or CesiumJS.
- Aerospace & mission-system experience - Background in aerospace, defense, or high-integrity engineering.
- MBSE tooling - Experience with Cameo, Teamwork Cloud, or similar tools.
- Requirements management - Experience with Jama, DOORS, or comparable systems.
- Systems engineering certifications - INCOSE ASEP/CSEP, OCSMP, or related credentials.
- Travel readiness - Ability to travel 10-15% as required.
- Security eligibility - U.S. Citizen; able to obtain and maintain DoD Secret clearance (TS/SCI preferred).
