Software Engineer , Spacecraft Simulation; New Grad

Space is a war fighting domain. True Anomaly seeks those with the talent and ambition to build the technology that secures it.

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.

• Be the offset.We create asymmetric advantages with creativity and ingenuity.
• What would it take? We challenge assumptions to deliver ambitious results.
• It’s the people. Our team is our competitive advantage and we are better together.

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 an entry-level Spacecraft Simulation Software Engineer to help build and extend our spacecraft, constellation modeling, and simulation software with a focus on multi-physics, high-fidelity simulation.

This is a great opportunity for a recent graduate or early-career engineer to grow within a fast-paced, interdisciplinary team. You will learn from experienced engineers as you help develop algorithms for modeling complex coupled physics including 6-degree-of-freedom (6

DOF) rigid body dynamics, thermal systems, attitude dynamics and control, power systems, propulsion, and their interactions. You'll contribute to the simulation infrastructure that enables engineers to design spacecraft, validate control algorithms, analyze system performance, and predict mission outcomes with high confidence.

This is a 3 month temporary employment engagement. There is potential to convert to regular employment based on performance and business need.

• 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:
• 6
  
  DOF 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
• Participate in code reviews, architectural discussions, and sprint planning sessions, learning and applying our software quality standards and delivery practices

• Bachelor's degree in aerospace engineering, mechanical engineering, computer science, physics, a similar discipline, or equivalent practical experience
• Exposure to C++ (or a similar compiled language) through coursework, internships, personal projects, or research; familiarity with Python is a plus
• Foundational understanding of…
