Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
You will be responsible for the mechanical design of phased array antennas and subsystems throughout the entire development lifecycle, from concept to space flight. This includes performing mechanical analysis, managing thermal architecture, and presenting design reviews to customers and the executive team.
Candidates must hold a Bachelor of Science in Mechanical or Aerospace Engineering and possess at least 4 years of experience in space antenna and payload mechanical engineering. Proficiency in CAD tools, FEA, and advanced aerospace manufacturing techniques is required, along with excellent communication skills.
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 I to our Mechanical Engineering 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 design aspects of Cesium phased array antennas, 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 antennas and payloads. 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.
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.
\nJOB REQUIREMENTS AND MINIMUM QUALIFICATIONSCesiumAstro considers several factors when extending an offer, including but not limited to, the role and associated responsibilities, a candidate’s work experience, education/training, and key skills.
Please be aware that many roles will be subject to both security and export control restrictions. These restrictions mean that factors including new starter’s nationality, any previous or dual nationalities held, place of birth and country of residence may limit those roles that you can perform for the organization.
