About the Job

Requirements

A Bachelor of Science degree in Electrical Engineering or Computer Engineering from an accredited university is required.
A minimum of 5 years of industry experience in spacecraft electrical system design, analysis, manufacturing, testing, and troubleshooting is required; a master's degree may count as two years of experience.
Strong understanding of electronics and electrical engineering fundamentals is required.
Experience with spacecraft electrical-system subsystems, including processors, digital I/O, timing signals, power rails, and grounding, is required.
Experience with electrical-system design and analysis, including electrical interface control document definition, requirement derivation, digital I/O standards, power interfaces, connectors, and cabling, is required.
Hands-on experience using laboratory instruments such as oscilloscopes, spectrum analyzers, electronic loads, and signal generators to debug, test, and validate high-reliability electronics is required.
Experience with satellite electrical-system concepts, including data and memory budgets, telemetry, flight software controls, and electronics thermal management, is required.
Exposure to the space electronics supply chain, production issues, test processes, and flight operations is required.
Strong written and verbal communication skills are required.

Responsibilities

Perform technical definition, implementation, and verification of satellite avionics systems.
Define and maintain the command and data handling subsystem architecture and interfaces.
Conduct make-or-buy trades.
Represent the command and data handling subsystem by interfacing with satellite systems, mechanical, software, and assembly, integration, and test teams.
Collaborate on in-house solutions to advance 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 command and data handling subsystem block diagrams, subsystem-level analysis, make-or-buy trades, trade studies for purchased items, technical vendor interactions, subsystem design verification testing, hardware delivery, and on-orbit support.

Desired Qualifications

Experience with Python, C++, MATLAB, or other programming languages.
Experience with successful rapid prototyping, iteration, and flight delivery cycles.
Experience evaluating and testing hardware for effects due to total ionizing dose, single-event effects, electromagnetic interference, and related phenomena.
Familiarity with environmental testing, including thermal, shock, vibration, and thermal vacuum testing.

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 offering a $10,000 Sign On Bonus for this position.

We are looking to add a Senior Electrical Engineer toexecuteCommand and Data Handling (C&DH) subsystem development for our Element Satellite team. If you are great at what you do, 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 designing and delivering the C&DH subsystem for cutting-edge communication satellites. You will own the C&DH subsystem block diagram (in alignment with electrical architects), subsystem-level analysis, make-buy trades, trade studies for “buy” items, technical vendor interactions, subsystem Design Verification Testing (DVT), hardware delivery, and on-orbit support.

As a Satellite team member, you will work on a small team to develop satellites and put them in orbit. You will be a key point of contact for satellite software, mechanical, and AI&T teams. You will provide creative solutions to complex problems to push the boundaries of spacecraft design.
