Junior Simulation Software Engineer

METECS is seeking an entry-level Simulation Software Engineer to support NASA’s simulation efforts as part of the Robotics, Simulations, and Graphics Support (RSGS) team. This role is ideal for candidates with a strong foundation in computer science and software engineering who are interested in applying those skills to challenging problems in aerospace, robotics, human spaceflight, and physics-based simulation. In this role, you will contribute to the design, development, integration, testing, and maintenance of high-fidelity simulation software that supports engineering analysis across a wide range of human spaceflight programs, including the International Space Station (ISS), Orion, Moon Base, Space Reactor-1 Freedom (SR-1), Human Landing System (HLS), and other advanced exploration initiatives. Projects may include development and enhancement of core dynamics and simulation tools, investigations of crew member stability in lunar and microgravity environments, lunar vehicle simulations, and support of ISS training simulation systems. Successful candidates will be active contributors to a modern software development environment. Responsibilities include implementing and maintaining features from Git-managed work items, participating in peer code reviews, contributing to automated testing efforts, and helping maintain and improve continuous integration and deployment (CI/CD) pipelines. Candidates should be comfortable working within large, collaborative codebases and applying software engineering best practices to ensure reliability, maintainability, and performance. Simulation development at METECS is a highly multidisciplinary effort, requiring close collaboration with experts in software engineering, physics, robotics, biomechanics, computer graphics, and aerospace systems. You will work alongside NASA engineers and mission stakeholders to develop simulation capabilities that are accurate, robust, and relevant to real-world mission scenarios.
