Power Avionics Engineer

About Cowboy Space Corp:

Background
Cowboy Space Corporation is building the infrastructure to power and connect the orbital economy. Our modular, scalable satellites collect sunlight in Low Earth Orbit to enable multiple integrated applications: transmitting energy via infrared lasers (space-to-earth and space-to-space), powering on-orbit high-performance computing clusters (GPU/TPU), and providing secure, high bandwidth optical data transport.

Baiju Bhatt founded Cowboy Space Corporation in 2024. Inspired by his father’s work with NASA Langley Research Center, Baiju earned his B.S. in Physics and M.S. in Mathematics at Stanford before co-founding Robinhood, now a public company that has helped over 20 million Americans access the financial system. Cowboy Space Corporation has raised ~$365 million from Index Ventures, Interlagos, Construct Ventures, Breakthrough Energy Ventures, Andreessen Horowitz, NEA, and others.

This is an ambitious mission that demands extraordinary talent. Cowboy Space Corporation’s team has worked at places like SpaceX, Blue Origin, Stoke Space, Astranis and NASA, and is based in San Carlos, CA. If you're ready to solve complex technical challenges and help build the most important energy company in the world, we want to hear from you.

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 selection

• Knowledge of thermal management and its interaction with power electronics

• Experience with hardware-in-the-loop (HIL) testing and system integration

• Familiarity with FPGA or embedded systems as they relate to power control and monitoring

• Experience with reliability analysis (FMEA/FMECA, derating, fault tolerance)

• Ability to work in fast-paced, high-ownership environments with aggressive timelines

Compensation and Benefits

The salary range for this position is $120,000 – $175,000 annually. The actual base salary offered will depend on factors such as job-related skills, experience, qualifications, and internal equity.

• Equity in Cowboy Space Corp.

• 401(k) retirement savings plan

• Paid time off

• 10 paid holidays per calendar year

• Paid parental leave

• Relocation assistance if applicable
