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 Cesium hardware team is looking for Summer 2026 interns to design and build RF electronics hardware and antennas for satellite communication systems. RF hardware development interns will work closely with Cesium engineers on product development, schematic design, test, and manufacturing of space electronics. Areas of focus will include either board-level RF electronics design (e.g. front-ends with amplifiers, switches, filters, etc.) system design, or antenna design. Assignments will be determined by a mix of project availability and the interests of the successful candidates. Cesium interns regularly present their work to peers, mentors, and Cesium executive leadership throughout the course of the summer. As such, excellent written and verbal communication skills are required.
