Sr. Propulsion Engineer, Blue Thrusters Valves

Application close date:
Applications will be accepted on an ongoing basis until the requisition is closed.

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 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 a Senior Propulsion Engineer on the Blue Thrusters team, you will serve in a technical leadership capacity over a product line of flight-critical valve hardware, including direct acting solenoid and pneumatically piloted valves. You will be the go-to technical authority for your product line—driving the tools, processes, and standards that govern how we design, build, and test these systems. You will guide engineers from initial requirements definition through qualification and into production, working closely with cross-functional teams to ensure every valve we deliver meets the highest standards of performance and reliability.

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!

• Serve as the technical lead and subject matter expert for the Blue Thrusters Valve product line, encompassing direct acting solenoid and pneumatically piloted valve designs
• Mentor valve responsible engineers, developing their expertise in design, manufacturing, and test
• Develop, establish, and maintain team-wide design, build, and test tools, processes, and standards to ensure consistency, quality, and efficiency across the product line
• Perform and review fluid, structural, and electromagnetic analysis for definition and validation of requirements across pressure, temperature, electrical, and dynamic environments.
• Document these processes and results to build a technical basis for use among engineers.
• Define and implement margin strategies to ensure products meet requirements without excessive cost and mass impacts
• Collaborate with systems, propulsion, electrical, and software engineers to define interfaces, refine requirements, and integrate valve hardware into broader thruster systems
• Lead design reviews, provide technical mentorship to junior engineers, and contribute to a culture of engineering excellence and continuous improvement
• Engage with suppliers to drive component development, ensure quality, and resolve technical issues throughout the supply chain
• Support fabrication, assembly, and testing of development and flight hardware; review and disposition non-conforming hardware with sound engineering judgment
• Author and review technical reports, qualification packages, test plans, and engineering specifications

• Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or a related field
• 8+ years of industry experience designing and developing fluid control hardware, with demonstrated expertise in valve design for aerospace or high-reliability applications
• Hands-on experience with both electromechanical (solenoid) and pneumatically actuated valve designs
• Strong technical fundamentals in fluid mechanics, thermodynamics, mechanical design, electromagnetic design, and structural mechanics
• Proficiency in 3D CAD software (Creo preferred) and experience creating…
