About the Role

<div class="content-intro">Space is a warfighting domain. True Anomaly seeks those with the talent and ambition to build the technology that secures it. OUR MISSION True Anomaly delivers decisive capabilities for space superiority. We build autonomous spacecraft, advanced payloads, mission software, and space-based interceptors — enabling the U.S. and its Allies to secure the space environment and counter threats from the ultimate high ground. OUR VALUES <ul> <li class="ms-outlook-mobile-reference-message">Be the offset. We create asymmetric advantages with creativity and ingenuity.</li> <li class="ms-outlook-mobile-reference-message">What would it take? We challenge assumptions to deliver ambitious results.</li> <li class="ms-outlook-mobile-reference-message">It’s the people. Our team is our competitive advantage and we are better together.</li> </ul></div>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 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. 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. RESPONSIBILITIES Simulation Development <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> <li>Design time-stepping algorithms, solver architectures, and integration schemes for real-time and faster-than-real-time simulation</li> <li>Write production-quality C++ with emphasis on performance, maintainability, and testability</li> </ul> API Design & Integration <ul> <li class="whitespace-normal break-words pl-2" data-uuid="2880e2b4-8d8d-44d0-9f8b-99fa87386ef4">Design and maintain robust APIs in C++ and Python serving internal customers across the organization</li> <li class="whitespace-normal break-words pl-2" data-uuid="c570465e-4e5d-4276-bacd-713a165a30af">Collaborate with mission planning, GNC, and systems engineering teams to ensure APIs are usable, performant, and backward-compatible</li> <li class="whitespace-normal break-words pl-2" data-uuid="8a457493-cafe-49cc-ae88-19ef51028243">Create comprehensive documentation, examples, and user guides</li> </ul> Leadership & Collaboration <ul> <li class="whitespace-normal break-words pl-2" data-uuid="58604b1d-6aa0-48a7-8282-157b3ce00c28">Drive architectural decisions for simulation subsystems, including technology selection, interface design, and long-term maintainability tradeoffs;
