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 Electrical Engineer to our Digital and Mixed-Signal Electronics team. If you are great at what you do, enjoy working in a startup environment, and are passionate about developing leading-edge electronics for satellites, spacecraft, and aerospace systems, we would like to hear from you.
At the Senior level, you will be tasked with full-stack hardware development for complex modules. You will have the opportunity to start at concept development and progress through detailed design, analysis, layout, build, test, and delivery, doing hands‑on work at each phase.
At a small company and a startup, your work will make direct contributions to the success of the business. The work is challenging and impactful, requiring both breadth and depth of technical knowledge. Our products are made for high-reliability space and airborne applications, so designs require high levels of technical rigor while maintaining the agility of a startup environment.
The successful candidate will also present engineering design review materials to our customers and executive team. As such, excellent written and verbal communication skills are required.

JOB DUTIES AND RESPONSIBILITIES

Own end-to-end design of electronics modules, from concept and architecture through schematic, layout, test, and production
Own the digital and mixed-signal portions of complex RF electronics, such as phased array control circuitry
