Software Engineer I, Spacecraft Simulation (New Grad)

Back to jobs Software Engineer I, Spacecraft Simulation (New Grad) Denver, CO; Long Beach, CA Apply 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

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.

BENEFITS & PERKS *

Best-in-class healthcare: 100% company-paid medical, dental, and vision coverage for you and your dependents, with HSA/HRA options Generous time off: Flexible Time Off (FTO) for exempt employees, accrued PTO of up to 25 days for non-exempt employees, plus 12 paid holidays; Parental Leave; Sick Leave Fuel for your day: Daily catered lunch and unlimited snacks for in-office employees And more: 401(k) retirement plan, fitness reimbursement, and Dog Fridays Equity participation: Equity is included as part of our total compensation package, giving you an opportunity to share in the company’s success.

*Do not apply to fixed term and temporary roles 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 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 (6DOF) 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. 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
