Staff Electrical Engineer – Satellite C&DH Subsystem - $10K Sign On Bonus

CesiumAstro•El Segundo, CA

About The Position

CesiumAstro is seeking a Staff Electrical Engineer to lead Command and Data Handling (C&DH) subsystem development for its Element Satellite team. The role is responsible for designing and delivering the C&DH subsystem for high-volume communications satellites, including subsystem architecture, analysis, make-buy and trade studies, vendor interactions, design verification testing, hardware delivery, and on-orbit support. The engineer will work with satellite architects and internal component development teams to shape a long-term roadmap and will be a key contact for satellite software, mechanical, and AI&T teams. The role involves hands-on, cross-functional work in a startup environment and delivering reliable, high-performance space avionics for spaceflight missions. A $10,000 sign-on bonus is offered. Applicants must meet U.S. space technology export-control eligibility requirements.

Requirements

Bachelor of Science degree in Electrical or Computer Engineering from an accredited university.
At least 8 years of industry experience in spacecraft electrical system design, analysis, manufacturing, testing, and troubleshooting. A master's degree may count as two years of experience.
Strong understanding of electronics and electrical engineering fundamentals.
Understanding of spacecraft electrical subsystems and components, including processors, digital I/O, timing signals, power rails, and grounding.
Experience with successful rapid prototyping, iteration, and flight-delivery cycles.
Proficiency in electrical system design and analysis, including electrical ICD definition, requirement derivation, digital I/O standards, power interfaces, connectors, and cabling.
Hands-on experience using laboratory instruments such as oscilloscopes, spectrum analyzers, electronic loads, and signal generators to debug, test, and validate high-reliability electronics.
Experience with satellite electrical system concepts, including data and memory budgets, telemetry, flight software controls, and electronics thermal management.
Understanding of the space electronics supply chain, production issues, test processes, and flight operations.
Excellent written and verbal communication skills.
Must be a U.S. citizen, lawful permanent resident, conditional resident, asylee or refugee, or eligible to obtain required U.S. Department of State authorizations.

Nice To Haves

Experience with multiple distinct spacecraft electrical architectures that informs a vision for next-generation spacecraft.
Experience with Python, C++, MATLAB, or other programming languages.
Experience evaluating and testing hardware for effects due to TID, SEE, EMI, and related phenomena.
Familiarity with environmental testing, including thermal, shock, vibration, and TVAC.

Responsibilities

Direct technical definition, implementation, and verification of satellite avionics systems.
Define and maintain C&DH subsystem architecture and interfaces.
Conduct make-buy trades and trade studies for items selected for purchase.
Represent C&DH in coordination with satellite systems, mechanical, software, and AI&T teams.
Collaborate on in-house solutions to improve satellite performance and manufacturability at scale.
Make decisions with limited input and analysis while driving the team to produce and iterate hardware.
Design and execute box-level and subsystem-level test plans for design verification, qualification, and/or acceptance testing.
Prepare and deliver technical communications to company leadership and executives.
Deliver reliable, performant space avionics systems for spaceflight missions.
Own subsystem-level analysis, technical vendor interactions, subsystem DVT, hardware delivery, and on-orbit support.
