Job summary

True Anomaly, Inc. seeks a Senior Spacecraft Simulation Software Engineer to advance high-fidelity, multi-physics simulation for spacecraft and ground systems.

You will own significant components, design algorithms for 6DOF dynamics, thermal modeling, and propulsion, and mentor junior engineers in a fast-paced, interdisciplinary team. The role emphasizes hands-on development in C++/Python, API design, and collaboration with mission planning and systems engineering.

Qualifications

• Bachelor's degree in aerospace engineering, mechanical engineering, computer science, physics, applied mathematics, or equivalent experience.
• 5-8 years of professional software development with significant focus on simulation, scientific computing, or aerospace applications.
• Proficiency in modern C++ (C++17 or newer), including STL, templates, and performance optimization.
• Proficiency in API design, scripting, and data analysis.
• Demonstrated ability to take ambiguous requirements and drive a complex technical effort to delivered capability with minimal direction.

Responsibilities

• Design and implement multi-physics simulation software across spacecraft subsystems (6DOF dynamics, thermal, attitude dynamics and control, propulsion, power, and sensor/actuator models).
• Develop coupled physics algorithms capturing subsystem interactions.
• 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.
• 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.
• Drive architectural decisions for simulation subsystems and mentor junior engineers.
