Thermal Analysis Engineer

Are you passionate about human space exploration, understanding the origins of the universe, and working with a passionate and diverse team to make a difference? If you are, we need you! We need your talent, teamwork, and energy to help us achieve great things that inspire people all over the globe. We need you to bring creative ideas and diverse backgrounds to help us envision, shape, and deliver systems that will enable the exploration of space while benefiting people here on Earth. We are excited about what we do, and we need you on our team as we take on exciting challenges for NASA’s pursuits in deep space exploration. As NASA’s largest engineering solutions provider working together with NASA at centers across the United States. Amentum has an exciting opportunity for a Thermal Analysis Engineer to join the team with Barrios, a teammate company. The Thermal Analysis Engineer will support the development, analysis, and verification of thermal control systems that contribute to NASA's human spaceflight missions. The engineer will collaborate closely with NASA customers, subsystem teams, and cross‑disciplinary engineering groups to deliver reliable thermal solutions for both crewed and uncrewed vehicles. Key Responsibilities: Develop and maintain simplified to high‑fidelity thermal models using Thermal Desktop, SINDA/FLUINT, and related tools. Perform steady‑state and transient thermal analyses for spacecraft components, subsystems, and integrated vehicle configurations. Evaluate thermal performance across mission phases, including ascent, cruise, lunar orbit, surface operations, and off‑nominal scenarios. Perform thermal sensitivity studies in support of vendor vehicle designs, GFE designs or requirement development. Support thermal verification and validation activities, including test planning, thermal vacuum testing, data analysis, and model correlation. Collaborate with design teams to optimize PTCS and ATCS architectures. Provide guidance on thermal design considerations and ensure compliance with NASA requirements and best practices. Participate in design reviews, technical interchange meetings, and anomaly investigations. Review NASA and vendor thermal designs for technical accuracy and requirement compliance. Document analysis results, prepare technical reports, and present findings to internal stakeholders and NASA customers. Support integration with systems engineering, mission operations, and hardware development teams throughout the engineering lifecycle. ​​ Are you passionate about human space exploration, understanding the origins of the universe, and working with a passionate and diverse team to make a difference?
