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 seeking a highly skilled Senior Staff Electrical Engineer to lead the design, development, integration, test, and flight qualification of advanced spaceborne payloads.
This post focuses on the role of Payload Lead Engineer (aka Responsible Engineer) in our Phased Array product line, focusing on Ka-band Active Electronically Steered Arrays (AESAs). CesiumAstro AESAs are state-of-the-art electronics assemblies consisting of an antenna element array, RF electronics, digital array control, and power conversion – engineered into a single box using a modular but optimized approach.
The Payload Lead is responsible for the technical development of a new payload product consisting of a phased array (AESA) and a processing unit (RPU). This combines deep, multi-disciplinary technical accountability with responsibility for on-time schedule execution.
The Payload Lead is the leader of the multidisciplinary technical team, the primary point of contact for the program manager, and often a key interface point for our customers. Success in this role requires deep expertise in technical topics as well as project management, leadership, and communication in a fast-paced startup environment.
