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 Staff Electrical Engineer to our Digital/Mixed-Signal Electronics team. If you 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 and small systems. 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. The Senior level also introduces technical leadership opportunities, gaining responsibility for small teams of hardware engineers developing new products and systems.

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.
