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.

The Skylark product line is focused on the rapid design, build, and test ofcutting-edgeactive phased array antennas (AESA) for terrestrial and airborne applications. Current programs span high-power, large-scale ground terminals for missile defense to commercial airline and helicopter connectivity solutions.

We are looking to add a Senior Mechanical Engineer 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 mechanical designs of CesiumAstro products through all phases of the development process. The ideal candidate will be proficient in electronics packaging design, mechanical simulations and analyses, computer‑aided design (CAD), aircraft mechanical interfaces, and environmental qualification of electronic assemblies (MIL-STD‑810 and DO‑160G).

As a CesiumAstro 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 field 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, environmental compatibility analysis, geometric dimensioning and tolerancing (GD&T), finite element analysis (FEA), and cost analysis to develop, validate, and optimize mechanical designs.

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