Senior Software Engineer, Spacecraft Simulation
Key Skills for This Role
Full Job Posting
Simulation Development
Design and implement multi-physics simulation software across spacecraft subsystems: 6DOF rigid body dynamics (gravity gradient, solar radiation pressure, atmospheric drag, magnetic torques, third-body effects), thermal modeling, attitude dynamics and control, propulsion (chemical/electric), power generation and storage, and high-fidelity sensor/actuator models (reaction wheels, CMGs, star trackers, gyros, magnetometers)
Develop coupled physics algorithms capturing subsystem interactions (thermal-structural, power-thermal, propulsion-dynamics)
Design time-stepping algorithms, solver architectures, and integration schemes for real-time and faster-than-real-time simulation
Write production-quality C++ with emphasis on performance, maintainability, and testability
API Design & Integration
Design and maintain robust APIs in C++ and Python serving internal customers across the organization
Collaborate with mission planning, GNC, and systems engineering teams to ensure APIs are usable, performant, and backward-compatible
Create comprehensive documentation, examples, and user guides
Leadership & Collaboration
Drive architectural decisions for simulation subsystems, including technology selection, interface design, and long-term maintainability tradeoffs; conduct thorough code reviews
Mentor junior engineers through pair programming and technical guidance
Contribute to sprint planning, estimation, and technical risk assessment
Participate in hiring through technical interviews and candidate assessment
