At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We're working to develop reusable, safe, and low-cost space vehicles and systems within a culture of safety, collaboration, and inclusion. Join our diverse team of problem solvers as we add new chapters to the history of spaceflight!This role is part of the Lunar Permanence business unit. To further Blue Origin's mission of having millions of people living and working in space, we are building the sustainable infrastructure for our transport of crew and cargo from Earth to the Lunar Surface.As part of a diverse and hardworking team of engineers, you will contribute to the definition and development of spacecraft thermal control systems. You should be comfortable working in a fast-paced and often uncertain environment, contributing to innovative solutions, while demonstrating personal leadership, technical competence, and attention to detail.You will work directly with NASA and our National Team Partners as part of the Human Landing System (HLS) Sustaining Lunar Development (SLD) program. You will play a key role in developing the Lunar Transportation system that will return humans to the Moon, this time to stay.You will be a Thermal Systems Engineer IIIwithin the Thermal Integrated Product Team (Thermal IPT). You will be responsible for performing and leading Systems Engineering (SE) tasks and delivering SE-related products. This person will work closely with the Thermal Analysts and Designers, but also across all other IPTs to ensure successful execution of the Thermal Subsystem in the larger spacecraft and mission. Contribute to a team of Thermal Engineers simultaneously developing groundbreaking lunar landers.We are looking for someone to apply their technical expertise, leadership skills, and commitment to quality to positively impact safe human spaceflight. Passion for our mission and vision is required!Responsibilities:Develop & manage Thermal specifications and requirements (at subsystem and component-levels)Develop & manage Thermal interfaces, including Interface Control Documents (ICDs) and models (in collaboration with adjacent IPTs)Decompose requirements from system and subsystem-levels into lower-level requirementsMentor early-career Thermal Systems Engineers on the Lunar ProgramStandardize Thermal Systems Engineering approachesOwn the verification and validation of Thermal requirements, in collaboration with the Thermal test engineersPerform traceability analysis of requirements to higher levels, and to verification activitiesLead trade studies across the Thermal IPT and with other IPTsServe as the Thermal point-of-contact for other IPTsUtilize Systems Engineering tools such as Jama, Windchill and CameoSupport and present at major gated reviews including design reviews, readiness reviews, etc.Minimum Qualifications:Minimum of a B.S. degree in mechanical or aerospace engineering5+ years of relevant Thermal Engineering or Systems Engineering experience on space missionsUnderstanding of heat transfer fundamentals in space environmentStrong understanding and application of Systems Engineering fundamentals in a few areas such as Requirements management, Verification, and/or IntegrationFamiliarity with common spacecraft thermal hardwareStrong understanding of aerospace hardware verification and validation processAbility to earn trust, maintain positive and professional relationships, and contribute to a culture of inclusion.Must be a U.S. citizen or national, U.S. permanent resident (current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.Preferred Qualifications:M.S. or PhD degree in mechanical or aerospace engineering8+ years of relevant Thermal Engineering or Systems Engineering experience on space missionsSolid und
