Software Engineer, Missile Defense Simulation (II - Principal)

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 Modeling and simulation is how True Anomaly turns operational problems into engineering decisions. Before a spacecraft flies or an interceptor engages, our simulations tell us whether the architecture will work, how it will perform against a thinking adversary, and where the margins really are. True Anomaly is seeking a Modeling & Simulation Engineer to build and run the mission- and engagement-level simulations that drive design, concept-of-operations, and acquisition decisions across our space and missile defense portfolio. You will work in a fast-paced, interdisciplinary team to model threats, sensors, spacecraft, interceptors, and command-and-control (C2) systems. This role focuses on building credible, validated simulation environments and turning their results into clear recommendations for engineers, program leadership, and government customers.
