Principal GN&C Mission Design Engineer

Company Details

Millions of people living and working in space to benefit Earth.

Blue Origin is self-funding rapid development of multiple in-space flight systems – over a range of sizes, propellant types, and technical challenge. Our versatile spacecraft will serve a wide variety of customers for missions from low Earth orbit to the far side of the moon. On these unique programs, you will experience the full lifecycle from formulation to flight in a short time, while achieving historic milestones!

As part of a hardworking team of diverse spacecraft development engineers, you will study and develop advanced concepts for in-space systems, planetary landers, and crewed vehicles. You will lead teams responsible for solving challenging problems in trajectory analysis and mission design of various spaceflight systems. This position will directly impact the history of space exploration, and your dedicated commitment and detailed attention will further the cause of safe and repeatable spaceflight.

We are looking for someone to apply their technical expertise, leadership skills, and commitment to quality to positively impact safe spaceflight. Passion for our mission and vision is required!
