About the position

The Senior Spacecraft Electrical Engineer I at CesiumAstro is responsible for the design, integration, and verification of spacecraft electronics and hardware throughout the development process for space systems. This role involves working on various subsystems including avionics, power generation, and telemetry, while providing creative solutions to complex engineering challenges. The position requires collaboration within a small team to develop cutting-edge communication satellites and support their deployment into orbit.

Responsibilities

• Direct technical implementation and verification of satellite avionics systems.
• Create detailed design and analysis of satellite digital and power systems.
• Define and maintain subsystem and system block diagrams, schematics, and architecture drawings.
• Conduct make/buy trades.
• Architect and design in-house solutions.
• Prepare and deliver technical communications to team leadership, customers, and vendors.
• Deliver reliable, performant space avionics system for spaceflight missions.

Requirements

• Bachelor of Science (BS) degree in Electrical or Computer Engineering from an accredited university.
• Minimum of 4 years of industry experience in spacecraft electrical system design, analysis, manufacturing, test, and troubleshooting (a Master's degree may count as two years of experience).
• Strong understanding of electrical engineering fundamentals.
• Understanding of the subsystems required in a spacecraft electrical system.
• Board-level high-reliability hardware design experience for spaceflight thermal, radiation, and vibration environments.
• 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 with lab instruments such as oscilloscopes, spectrum analyzers, electronic loads, and signal generators.
• Experience with satellite electrical system concepts such as power and energy budgets, telemetry, flight software controls, and electronics thermal management.
• Familiarity with digital communications protocols including RS422, RS485, I2C, SPI, SpaceWire, or other low-level communication standards.
• Familiarity with photovoltaic solar cells and secondary battery chemistries.
• Familiarity with FPGAs and DSP/microprocessors.
• Experience in power and/or digital PCBA design, development, delivery, and operation.
• Experience in rapid prototype development and testing.
• Excellent written and verbal communication skills.

Nice-to-haves

• Familiarity with embedded systems and bare-metal microprocessor programming.
• Python, C++, MATLAB, or other programming languages.
• Familiarity with control systems and PMSM/BLDC motor control algorithms.
• Familiarity with environmental testing including thermal, shock, vibration, and TVAC.
• Familiarity with EMI/EMC qualification to MIL-STD-461 and GEVS or similar standard.
• Familiarity with analog, digital and mixed-signal circuit analysis, simulation, design, test, and troubleshooting.
• Familiarity with evaluating and testing hardware for radiation effects including TID, SEE, and relevant phenomena.
• Familiarity with ADS SI/PI or similar Signal Integrity / Power Integrity analysis tools.
