<p class="code-line">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 Senior Spacecraft Simulation Software Engineer to drive the development and enhancement of our spacecraft, constellation modeling, and simulation software with a focus on multi-physics, high-fidelity simulation.</p>

<p class="code-line">You will take ownership of significant technical components within our simulation infrastructure, working independently to design, implement, and deliver complex features. Working in a fast-paced, interdisciplinary team, you will develop algorithms for modeling coupled physics including 6-degree-of-freedom (6DOF) rigid body dynamics, thermal systems, attitude dynamics and control, power systems, propulsion, and their interactions. You will also mentor junior engineers and contribute to architectural decisions that shape the future of our simulation capabilities.</p>

<p><strong>RESPONSIBILITIES</strong></p>

<p><strong>Simulation Development</strong></p>

<ul>

<li>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)</li>

<li>Develop coupled physics algorithms capturing subsystem interactions (thermal-structural, power-thermal, propulsion-dynamics)</li>
