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 Principal Mechanical Design Engineer II to our team. If you are great at what you do, enjoy working in a startup environment, and are passionate about developing leading-edge hardware for satellites, spacecraft, and aerospace systems, we would like to hear from you.
In this position, you will be responsible for the mechanical design of Cesium products through all phases of the development process. The ideal candidate will have extensive experience in electronics packaging design, mechanical simulations and analyses, computer-aided design (CAD), spacecraft mechanical interfaces, and environmental qualification of electronic assemblies.
As a principal mechanical team member, you will be responsible for mechanical designs from initial concept design through requirements definition, detailed design, simulation, analysis, manufacturing, testing, qualification, and in-orbit support of Cesium's products. Required skills and experience include thermal management design, precision machining principles, thermal simulation and analysis, shock and vibration simulation and analysis, electromagnetic interference/compatibility (EMI/EMC) mitigation techniques, geometric dimensioning and tolerancing (GD&T), finite element analysis (FEA), and cost analysis to develop, validate, and optimize mechanical designs. Principal engineers also serve as technical and professional mentors in their field.
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.
