Job Description
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. 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 Principal Spacecraft Simulation Software Engineer to define the long-term technical vision and architecture for a simulation platform that spans some of the hardest problems in modern aerospace — from high-fidelity multi-physics modeling of spacecraft and constellations to simulation of complex, dynamic environments that don't yet have established playbooks. At this level, your impact extends well beyond individual features. The platform you help shape will underpin mission planning, autonomy development, GNC validation, and operational decision-making across a range of scenarios that are technically novel by design. You will set technical direction across the simulation organization, serve as the internal authority on simulation methodology and best practices, and drive the technical culture of the team. Responsibilities Technical Vision & Architecture Own the long-term technical strategy and architectural roadmap for True Anomaly's simulation infrastructure, spanning multi-physics modeling, real-time, faster-than-real-time execution, and hardware/software-in-the-loop environments Make high-consequence architectural decisions — technology selection, inter-system interface design, performance targets, and long-term maintainability tradeoffs — with full awareness of downstream impact across engineering, GNC, mission planning, and operations Identify and resolve fundamental technical risks before they become program-level blockers; anticipate capability gaps 12–24 months out and drive proactive investment Establish and steward engineering standards, simulation best practices, and V&V frameworks adopted across the organization Simulation Development Lead the design and implementation of production-quality multi-physics simulation software spanning 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) Architect and implement tightly coupled physics algorithms capturing complex subsystem interactions (thermal-structural, power-thermal, propulsion-dynamics) with rigorous attention to numerical stability, accuracy, and performance Design advanced time-stepping algorithms, solver architectures, and integration schemes that support scalable, real-time, and batch simulation use cases Write production-quality C++ with emphasis on performance, correctness, maintainability, and testability; establish the quality bar others rise to meet API Design & Integration Define the simulation platform's external-facing API strategy across C++ and Python, ensuring interfaces are intuitive, performant, versioned, and backward-compatible as the platform evolves Partner with mission planning, GNC, systems engineering, and autonomy teams to understand capability needs and translate them into durable, well-documented platform investments Drive creation of comprehensive documentation, developer guides, and reference examples that enable self-service across the organization Leadership & Collaboration Serve as a technical anchor across the simulation team; provide architectural guidance, unblock decisions, and ensure coherent execution toward shared goals Drive a culture of engineering excellence through rigorous code reviews, mentorship, pair programming, and knowledge transfer Mentor engineers at all levels; contribute directly to career development conversations and growth planning Partner with engineering leadership to shape simulation capability roadmaps, surface tradeoffs, and contribute to proposals and techn
