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 Blue Origin Engines business unit, where our focus is the design, development, manufacturing and testing of engines and propulsion systems. Built for multiple uses, our family of engines is powering the next generation of rockets for commercial, civil, national security and human spaceflight.As part of a hardworking team of diverse engineers, you will be responsible for championing mass properties process and tools improvements, relentlessly focusing on value and seeking to eliminate waste in our processes and tools whenever possible. You will also execute mass properties management on one or more engines programs. Your engagement spans all program phases, from conceptual design, through development, production, deployment, and post-flight. This work will require close partnership with other enterprise engineers in mass properties, manufacturing, quality, cost, and software development. Your ability to partner and earn trust with folk across the organization is essential to our success.Responsibilities include but are not limited to:Perform mass control, analysis, verification, data management, and documentation for one or more engine program.Deliver accurate mass properties calculations throughout the program lifecycle - done with and without the aid of 3D CAD modelsDefine mass properties allocations in collaboration with subsystem/component teamsSupport decision-making on design and manufacturing tradesIdentify and actively manage mass risks and opportunities for the engine, partnering with component design engineersRegularly forecast engine system mass, using your deep, personal understanding of engine component designs and their development maturityOwn mass properties verification plan - driving execution of these activities, developing rationale for when to weigh parts and when to rely solely on analysisCreate weight and balance procedures to measure mass, center of gravity, and moments of inertia, as needed.Identify mass properties process and tools improvement needs and develop an improvement roadmap.Minimum Qualifications:Minimum of a B.S. degree in mechanical, aerospace engineering, or a relevant technical degree7+ years of experience in aerospace engineering or complex electromechanical systems4+ years in mass properties engineering with aerospace or complex electro-mechanical productsExpertise in technical fundamentals of mass engineering, calculations, forecasting, and reportingExpertise with mass properties control processes, including identifying and resolving mass property threats and opportunitiesSignificant experience developing and improving mass properties process and tool chainsExpertise in systems engineering practices and configuration managementExtensive computer skills including MS Excel, MATLAB, and CAD (Creo preferred)Experience weighing aerospace parts and complex assembliesDemonstrated ability to earn trust, develop collaborative professional relationships, and contribute to a culture of inclusionDemonstrated experience pulling teams together to solve complex system problemsExcellent technical writing and presentation skillsMust 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:10+ years working in aerospace engineering field7+ years in mass properties engineering with aerospace or complex electro-mechanical productsWorking knowledge or experience with liquid rock
