Trueanomalyinc Software Engineer I, Spacecraft Simulation develops multi-physics, high-fidelity spacecraft simulation software using modern C++. Focuses on modeling coupled physics including rigid body dynamics, thermal systems, and propulsion.

Responsibilities

Write well-structured, efficient code using modern C++ (C++ 17 / C++ 20), with attention to performance and maintainability, guided by code reviews and team standards
Contribute to 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)
Help implement coupled physics algorithms that capture interactions between subsystems (thermal-structural, power-thermal, propulsion-dynamics, etc.), with guidance from senior engineers
Assist in developing and testing time-stepping algorithms, solvers, and integration schemes for real-time and faster-than-real-time simulation
Help maintain libraries that provide APIs in multiple languages (Python, C++) to other applications within True Anomaly
Collaborate with other internal teams who leverage our simulation APIs to plan and execute missions, develop algorithms for spacecraft operation, and perform trade-space analyses
