## Description

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., * 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
