Job description

Power Avionics Engineer

About Cowboy Space Corp:

Cowboy Space Corp. is building the infrastructure to power and connect the orbital economy. Our satellites operate in Low Earth Orbit to collect sunlight and enable a new class of capabilities—from powering on-orbit compute, to transmitting energy via infrared lasers (space-to-earth and space-to-space), powering on-orbit compute to delivering secure, high-bandwidth optical data. By rethinking how energy and data are generated and distributed in space, we’re unlocking entirely new ways to operate both in orbit and on Earth.

Founded in 2024 by Baiju Bhatt (co-founder of Robinhood), Cowboy Space Corp. is backed by leading investors and built by a team from top aerospace and defense organizations. We’re moving quickly to solve complex technical challenges and build a new category of space infrastructure.

About the Role

The Power Electronics Engineer role is responsible for the design, development, and integration of electrical systems supporting high power solar arrays and compute payloads. You will collaborate with software, mechanical, solar, and propulsion engineers to develop solutions that meet rigorous performance standards for space applications.

Responsibilities

• Own the design, development, and validation of spacecraft power electronics systems from concept through flight
• Architect and implement power distribution systems, including power management, conversion, and regulation for spacecraft subsystems
• Design and analyze DC-DC converters, battery management systems (BMS), and power control electronics for high-reliability environments
• Develop and execute test plans for power systems, including functional, environmental, and hardware-in-the-loop (HIL) testing
• Perform system-level analysis of power budgets, efficiency, thermal performance, and fault conditions
• Implement protection and fault management strategies (overcurrent, overvoltage, short circuit, latch-up protection)
• Partner closely with structures, thermal, software, and payload teams to ensure seamless integration of power systems
• Support board bring-up, integration, and debugging of power electronics in lab and flight environments
• Investigate anomalies and drive root cause analysis to improve system robustness and reliability
• Support vehicle integration, pre-flight testing, and on-orbit performance analysis

Basic Qualifications

• Bachelor’s degree in Electrical Engineering or a related field
• 3+ years of experience designing or testing power electronics or avionics systems
• Strong understanding of power electronics fundamentals (DC-DC conversion, control systems, power distribution)
• Experience with schematic capture, PCB design, and board bring-up
• Familiarity with lab equipment (oscilloscopes, power supplies, electronic loads) and debugging techniques
• Experience working in high-reliability or hardware-focused environments

Preferred Qualifications

• Experience designing power systems for spacecraft, aerospace, or other harsh environments
• Familiarity with battery systems, solar arrays, and energy storage technologies
• Experience with radiation-tolerant design and component selectionJSON JSON bebê. No more
