Overview

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 part of a hardworking team of specialists, technicians, and engineers (use as appropriate), you 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 group of accomplished industry experts, you will be used as a material expert within Blue Origin’s Engines Business Unit demonstrating and developing technology on propulsion projects ongoing and planned. You will leverage your extensive experience in materials, advanced manufacturing, and process development to support engine products through system engineering, modeling and manufacturing methods, metallic and non-metallic materials, additive and subtractive manufacturing, joining processes, composites development and process development.

The position will require regular active participation with product and functional teams at Blue Origin’s headquarters in Kent, Washington and Blue Origins test locations through virtual or in-person attendance.

It is expected that you will have been involved in and understand how research flows into development which flows into production and operations on human/high value launch vehicle rocket propulsion. You will have ownership over design and development tasks. You will also mentor and advise younger team members to understand how you have been successful and unsuccessful in prior rocket engine efforts.

You will mentor M&P engineers and guide tactical and strategic program-related decisions. You will provide broad materials & processes support for metallic (e.g. forging, casting, forming, extrusion, plating, coating, brazing, anodization, passivation) and non-metallic (e.g. O-rings, seals, lubricants) hardware alike.

To be successful in this role, you must be able to collaborate closely with design, analysis, manufacturing, quality, and integration engineers to implement requirements. You will review production drawing for large complex assemblies systematically, documenting the review to the established requirements. Responsibilities include designing, collecting and statistically analyzing thermomechanical properties data for materials. You will lead material and part process development and qualification efforts.

Additionally, you will contribute to the development of internal engineering and quality processes to standardize and accelerate material evaluation, implementation, and qualification.
