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! We are a diverse team of collaborators, doers, and problem-solvers who are relentlessly committed to a culture of safety. This position will directly impact the history of space exploration and will require your commitment and detailed attention towards safe and repeatable space flight. Join us in lowering the cost of access to space and enabling Blue Origin's vision of millions of people living and working in space to benefit Earth. 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 aSenior Thermal Systems Engineerwithin 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 requirements Thermal point of contact for inputs to vehicle system safety products and risk management Mentor early-career Thermal Systems Engineers on the Lunar Program Standardize Thermal Systems Engineering approaches Own the verification and validation of Thermal requirements, in collaboration with the Thermal test engineers Perform traceability analysis of requirements to higher levels, and to verification activities Lead trade studies across the Thermal IPT and with other IPTs Serve as the Thermal point-of-contact for other IPTs Utilize Systems Engineering tools such as Jama, Windchill and Cameo Support and present at major gated reviews including design reviews, readiness reviews, etc. Qualifications: Minimum of a B.S. degree in mechanical or aerospace engineering 8 years of relevant Thermal Engineering or Systems Engineering experience on space missions Understanding of heat transfer fundamentals in space environment Strong understanding and application of Systems Engineering fundamentals in a few areas such as Requirements management, Verification, and/or Integration Familiarity with common spacecraft thermal hardware Strong understanding of aerospace hardware verification and validation process Ability 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
