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. ### RESPONSIBILITIES - Develop and maintain physics-based models for space and missile defense mission analysis, including: - Threat trajectories, including ballistic, hypersonic, maneuvering, and on-orbit threats - Space-based and terrestrial sensors (electro-optical/infrared, radar, RF), including detection, tracking, and discrimination performance - Interceptor and spacecraft kinematics, guidance, navigation, and control (GNC), and engagement geometry - Rendezvous and proximity operations (RPO), orbit determination, and space domain awareness (SDA) - Communications links, data latency, and C2/battle management decision logic - Build engagement- and mission-level simulations that tie these models together for end-to-end kill-chain analysis (detect, track, target, engage, assess) - Integrate models into digital engineering, software-in-the-loop (SIL), hardware-in-the-loop (HIL), and distributed simulation environments - Define and execute model verification, validation, and accreditation (VV&A), and correlate simulation results with test and flight data - Develop analysis tooling, automation, and visualization in Python and C++ - Collaborate with systems, GNC, payload, software, and flight-test engineers to support requirements development, test planning, and verification - Participate in code reviews, architectural discussions, and sprint planning sessions to maintain high standards of quality and adherence to project timelines - Run Monte Carlo, sensitivity, and trade studies, and brief results to internal and government stakeholders ### QUALIFICATIONS - Bachelor's degree in aerospace engineering, mechanical engineering, electrical engineering, physics, applied mathematics, computer science, a similar discipline, or relevant experience - 2+ years of professional experience in modeling and simulation, mission analysis, or aerospace/defense systems engineering --- Data: alder (https://alderhq.app).
