Software Engineer, Spacecraft Simulation

YOUR MISSION

Software is the central nervous system for True Anomaly's engineering and product thesis. Software bridges the gap between military objectives, theoretical physics, and the human and autonomous control of spacecraft and ground systems. True Anomaly is seeking a Spacecraft Simulation Software Engineer to contribute to the continuing evolution of our spacecraft, constellation modeling, and simulation software with a focus on multi-physics, high-fidelity simulation.

You will work in a fast-paced, interdisciplinary team to identify, develop, and deliver algorithms for modeling complex coupled physics including 6-degree-of-freedom (6DOF) rigid body dynamics, thermal systems, attitude dynamics and control, power systems, propulsion, and their interactions. This role focuses on building the simulation infrastructure that enables engineers to design spacecraft, validate control algorithms, analyze system performance, and predict mission outcomes with high confidence.

RESPONSIBILITIES

• Write well-structured, efficient code using modern C++ best practices (C++ 17 / C++ 20), with a particular emphasis on performance and maintainability
• Develop and maintain multi-physics simulation libraries for spacecraft systems modeling including:
  • 6DOF rigid body dynamics with environmental perturbations (gravity gradient, solar radiation pressure, atmospheric drag, magnetic torques)
  • Thermal modeling including conduction, radiation, and solar heating
  • Attitude dynamics and control system simulation
  • Propulsion system modeling (thrusters, tanks, mass properties)
  • Power generation and distribution (solar arrays, batteries, loads)
  • Sensor and actuator models (reaction wheels, star trackers, gyros, magnetometers, thrusters)
• Implement coupled physics algorithms that capture interactions between subsystems (thermal-structural, power-thermal, propulsion-dynamics, etc.)
• Design and implement time-stepping algorithms, solver architectures, and integration schemes for real-time and faster-than-real-time simulation
• Maintain libraries that provide APIs in multiple languages (Python, C++) to other applications within True Anomaly
• Work with other internal teams who leverage our simulation APIs to plan and execute missions, develop advanced algorithms for spacecraft operation, and perform trade-space analyses
• Participate in code reviews, architectural discussions, and sprint planning sessions to maintain high standards of software quality and adh
