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 looking to add a Senior Spacecraft Electrical Engineer I to our Internal Missions team. If you enjoy working in a startup environment and are passionate about developing electrical systems for leading-edge communications satellites, we would like to hear from you.

In this position, you will be responsible for spacecraft electronics and hardware through all stages of the development process for space systems. Your responsibilities will include ownership, design, and integration of various spacecraft subsystems including avionics, flight processors, data storage, intra-spacecraft digital communications and analog telemetry, power generation & storage, power distribution, grounding, EMI mitigation, and wiring & harness design for power and data interfaces between all spacecraft subsystems. The ideal candidate will be an electrical systems generalist motivated to deliver every aspect of the spacecraft electrical design from energy balance budgets to architectural and detailed hardware designs.

As a Cesium team member, you will work on a small team to develop satellites and put them in orbit. You will be responsible for electrical concepts, roadmaps, architecture trade studies, block diagrams, electrical hardware design, manufacturing, test, qualification, and in-orbit support. You will provide creative solutions to complex problems to push the boundaries of spacecraft design.

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.
