<div class="content-intro">Advanced Reentry Technologies Who We Are: Inversion is an aerospace and defense company pioneering advanced reentry technology to enable next-generation capabilities from space. By combining high-performance materials, precision aerodynamics, and mission-driven autonomy, Inversion is transforming reentry into an operational capability for an entirely new class of missions. The company’s highly maneuverable reentry spacecraft, Arc, is designed for rapid global cargo delivery, hypersonic testing, and other national security missions that require precise, controlled flight through the atmosphere. Arc creates an entirely new transportation domain, unlocking unprecedented speed and global reach. Headquartered in Los Angeles, Inversion designs, manufactures, and integrates its spacecraft under one roof, enabling the company to move rapidly from concept to flight. The company is backed by leading investors including Y Combinator, Spark Capital, and Lockheed Martin Ventures, with customers across the U.S. government and commercial space industry.</div>Position Overview:  As a Simulation Engineer at Inversion, you will focus on developing, automating, and maintaining the simulation and testing environments that validate our flight systems. You will play a key role in bridging the gap between GNC, Software, and Simulation teams, specifically supporting the pipeline that translates MATLAB-based GNC algorithms into autocoded C/C++ flight software. Working under the guidance of senior simulation engineers, you will build tools and workflows that enable fast, repeatable verification of flight software and hardware under realistic flight conditions using Software-in-the-Loop (SIL) and Hardware-in-the-Loop (HIL) environments.  Key Responsibilities: <ul> <li>Develop, test, and maintain simulation models for spacecraft subsystems, environmental dynamics, and hardware interfaces. </li> <li>Support the execution, automation, and scaling of Software-in-the-Loop (SIL) and Hardware-in-the-Loop (HIL) testing runs. </li> <li>Write and optimize data-processing pipelines and visualization scripts to analyze simulation outputs and verify vehicle-level requirements. </li> <li>Integrate internal guidance, navigation, and control (GNC) algorithms, aerodynamic databases, and sensor models into the core simulation platform. </li> <li>Develop and run automated unit tests, integration tests, and regression suites to ensure simulation platform stability. </li> <li>Maintain and troubleshoot simulation backend infrastructure, high-performance computing (HPC) nodes, and physical testbeds. </li> <li>Document simulation setups, API interfaces, and user guides to empower product engineering teams to run self-service simulation workflows. </li> </ul> Required Qualifications: <ul> <li>Bachelor’s degree in Computer Science, Computer Engineering, Aerospace Engineering, Mechanical Engineering, or equivalent
