At Lockheed Martin Space, we aim to harness the full potential of space to cultivate innovation, reduce costs, and push the boundaries of what technology can achieve. We’re creating future-ready solutions, focusing on resiliency and urgency through our 21st Century Security® vision. We’re erasing boundaries and forming partnerships across industries and around the world. We’re advancing spacecraft and the workforce to fuel the next generation. And we’re reimagining how space can connect us, ensuring security and prosperity. Join us in shaping a new era in space and find a career that's built for you. The Mechanical Engineer – Thermal Engineering (Level 2) will support the design, analysis, and validation of thermal systems for advanced aerospace and defense applications. This role involves conducting thermal analyses, developing thermal control solutions, and collaborating across multidisciplinary teams to ensure system performance in extreme environments. The selected candidate will perform steady-state and transient thermal modeling, support hardware development and test activities, and contribute to system-level integration efforts. This position requires strong analytical skills, attention to detail, and the ability to translate requirements into effective thermal design solutions.
