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 Spacecraft Simulation Software Engineer to contribute to the continuing evolution of our spacecraft, constellation modeling, and simulation software with a focus on multi-physics, high-fidelity simulation.

You" will work in a fast-paced, interdisciplinary team to identify, develop, and deliver 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. This role focuses on building the simulation infrastructure that enables engineers to design spacecraft, validate control algorithms, analyze system performance, and predict mission outcomes with high confidence.

RESPONSIBILITIES

• "
• Write" well-structured, efficient code using modern C best practices (C 17 / C 20), with a particular emphasis on performance and maintainability
• Develop" and maintain 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)
• Implement" coupled physics algorithms that capture interactions between subsystems (thermal-structural, power-thermal, propulsion-dynamics, etc.)
• Design" and implement time-stepping algorithms, solver architectures, and integration schemes for real-time and faster-than-real-time simulation
• Maintain" libraries that provide APIs in multiple languages (Python, C ) to other applications within True Anomaly
• Work" with other internal teams who leverage our simulation APIs to plan and execute missions, develop advanced algorithms for spacecraft operation, and perform trade-space analyses
• Participate" in code reviews, architectural discussions, and sprint planning sessions to maintain high standards of software quality and adherence to project timelines

QUALIFICATIONS

• "
• Bachelor's" degree in aerospace engineering, mechanical engineering, computer science, physics, a similar discipline, or relevant experience
• 1-3" years of professional experience in C
• Experience" with the Python programming language for scripting and prototyping applications
• Strong" understanding of object-oriented software development practices
• Ability" to understand new challenges quickly, formulate a plan, get buy-in, and execute
• Understanding" of complex distributed systems, and how the components you design and deliver will fit into those larger systems
• Excellent" problem-solving skills and attention to detail
• U.S." Citizen and eligible for DoD Secret or TS/SCI clearance

PREFERRED SKILLS AND EXPERIENCE

• "
• Experience" developing physics-based modeling and simulation environments (i.e., modeling spacecraft dynamics, thermal systems, or control algorithms)
• Knowledge" of numerical methods:
  • "
  • ODE" solvers and integration schemes (Runge-Kutta, etc.)
  • Numerical" linear algebra and matrix computations
  • Sparse" matrix techniques
• Experience" with spacecraft subsystems:
  • "
  • Attitude" determination and control systems (ADCS)
  • Guidance," navigation, and control (GNC)
  • Thermal" control systems
  • Electric" power systems (EPS)
  • Propulsion" systems
• Understanding" of coordinate frames and transformations (ECI, ECEF, body frame, etc.)
• Experience" with quaternion mathematics and rotation representations
• Knowledge" of orbital mechanics and perturbation forces
• Familiarity" with model validation, verification, and uncertainty quantification
• Experience" with version control systems (Git) and CI/CD pipelines

COMPENSATION

• Base Salary: $90,000 - $140,000
• Equity" Benefits" including Health, Dental, Vision, HRA/HSA options, PTO and paid holidays, 401K, Parental Leave "

Your actual level and base salary will be determined on a case-by-case basis and may vary based on the following considerations: job-related knowledge and skills, education, location, and experience. 

ADDITIONAL REQUIREMENTS

• Work Location-This is a fully onsite role. Candidates must be based in or able to commute to our Denver or Long Beach office daily.
• Work environment-the work environment; temperature, noise level, inside or outside, or other factors that will affect the person's working conditions while performing the job.
• Physical demands-the physical demands of the job, including bending, sitting, lifting and driving.
