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 Staff Mechanical Engineer to our team. If you are great at what you do, 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 leading a team of engineers responsible for mechanical aspects of CesiumAstro spacecraft, subsystems, and interfaces through all phases of the development process. The ideal candidate will be versatile and proficient in mechanical design, electronics packaging, computer-aided design (CAD), mechanical interfaces, thermal architecture, deployable and actuated structures, and environmental qualification of spacecraft. You will use these skills to effectively direct, mentor, and grow a team of upcoming engineers in the design of a novel satellite.

As a CesiumAstro spacecraft team lead and responsible mechanical authority, you will manage a small team to develop satellites and put them in orbit. You will be responsible for delivering robust mechanical designs from concept through space flight including requirements definition, architecture trades and block diagrams, analysis, manufacturing, assembly, testing, qualification, and in-orbit support. In this role you will also collaborate closely with GNC, EPS, CDH, Payload, RF, Systems, and AI&T teams.

The successful candidate will also present engineering design review materials to our customers and executive team, as well as participate in proposal-writing efforts. As such, excellent written and verbal communication skills are required.
