Job description

Please Note: To conform with the United States Government Space Technology Export Regulations, the applicant must be a U.S. citizen, lawful permanent resident of the U.S., conditional resident, asylee or refugee (protected individuals as defined by 8 U.S.C. 1324b(a)(3)), or eligible to obtain the required authorizations from the U.S. Department of State.

At CesiumAstro , we are developers and pioneers of out-of-the-box communication systems for satellites, UAVs, launch vehicles, and other space and airborne platforms. We take pride in our dynamic and cross-functional work environment, which allows us to learn, develop, and engage across our organization. If you are looking for hands-on, interactive, and autonomous work, CesiumAstro is the place for you. We are actively seeking passionate, collaborative, energetic, and forward-thinking individuals to join our team.

We are looking to add a Senior Mechanical Engineer to our Internal Missions team. If you enjoy working in a startup environment and are passionate about developing space hardware for leading-edge communications satellites, we would like to hear from you.

In this position, you will be responsible for mechanical aspects of Cesium spacecraft, subsystems, and interfaces through all phases of the development process. The ideal candidate will be versatile and proficient in mechanical analysis, electronics packaging, computer-aided design (CAD), mechanical interfaces, thermal architecture, spacecraft propulsion, deployable and actuated structures, and environmental qualification of spacecraft.

As a Cesium spacecraft team member, you will work on a small team to develop satellites and put them in orbit. You will be responsible for mechanical designs from concept through space flight including requirements definition, architecture trades and block diagrams, analysis, manufacturing, testing, qualification, and in-orbit support.

Your work will have a direct impact on the success of the company. You will work closely with the engineering team, program management to ensure the successful build and launch of our satellite.Element will be the largest, most powerful rideshare satellite in LEO.We’relaunching eight of them in the next four years, starting with our first launch this year.Together,our small team willdesign, build, and iterate to reduce mass and cost whileincreasing performance, reliability, and manufacturability of a new generation of satellites.Let’sbuild!

JOB REQUIREMENTS AND MINIMUM QUALIFICATIONS

• Bachelor of Science (BS) in Mechanical or Aerospace Engineering from an accredited university or institution.


• Minimum of 6 years of experience (including CubeSat projects) in spacecraft mechanical engineering to include electronics packaging, thermal, shock, vibration, stress dynamics, and cost. A Master’s degree may count as two years of experience.
