Mechanical Engineer

Samara Aerospace is revolutionizing satellite design by addressing the challenges of deploying and managing large satellite constellations. Our innovative Hummingbird spacecraft bus offers a modular and scalable platform that streamlines satellite production and deployment, significantly reducing launch costs. Hummingbird's compact architecture maximizes launch capacity, making it the most efficient and agile spacecraft in the industry. At the core of our technology is the patented Multifunctional Structures for Attitude Control (MSAC) system. Unlike traditional wheel-based pointing control systems, MSAC utilizes actuators embedded in the hinges of deployable solar panels to provide 3-axis attitude control and active jitter cancellation. This design eliminates the need for spinning wheels, reducing mass and potential points of failure, while enhancing pointing precision.

The Mechanical team at Samara is seeking a mechanical engineer to support the design, analysis, build, and testing of next-generation spacecraft at our headquarters in San Francisco. You’ll work closely with experienced mechanical and electrical engineers, gaining exposure to spacecraft structures, mechanisms, solar arrays, ground support equipment, and environmental testing in a fast-paced startup environment.
