Electrical Engineer Intern

About the role

WindBorne Systems is supercharging weather models with a unique proprietary data source: a global constellation of next-generation smart weather balloons targeting the most critical atmospheric data. We design, manufacture, and operate our own balloons, using the data they collect to generate otherwise unattainable weather intelligence. Our mission is to eliminate weather uncertainty, helping humanity adapt to climate change—whether predicting hurricanes or speeding the adoption of renewables. We are building a future where thousands of our microballoons instrument the planet, eliminating gaps in our understanding and empowering critical decision-making.

The founding team of Stanford engineers was named Forbes 2019 30 under 30 and is backed by top investors including Khosla Ventures. We're seeking an Embedded Electrical Engineer to lead hardware design, initial bringup, hardware debug, and manufacturing support for key elements of our flight hardware and ground support systems.

This role is ideal for someone who thrives on variety—jumping between PCB design, firmware debugging, and component sourcing—while finding satisfaction in making systems work in theory, in practice, and at scale. You’ll design systems that operate reliably from -70°C to +40°C using components unrated for such extremes, all while counting every gram and milliwatt. We value speed and pragmatism: quickly shipping designs that *don’t appear broken* and enjoying the challenge of troubleshooting inevitable issues at the bench.

Responsibilities

• Design, prototype, and test PCBs for critical new flight and ground systems
• Develop firmware for initial bringup of new boards and custom testing of existing boards
• Troubleshoot and resolve (only the most pressing) issues on existing hardware
• Conduct comprehensive bench and environmental testing to validate electrical systems under extreme conditions
• Work closely with mechanical engineers to ensure proper integration on a vehicle with about as many structural PCBs as custom 3D parts
• Support flight operations with troubleshooting of deployed hardware via realtime telemetry
• Coordinate PCBA manufacturing for both R&D and production

Requirements

• Strong fundamentals in embedded circuit and system design
• Hands-on experience troubleshooting circuit boards and electronic assemblies
• Proficiency with reading schematics and datasheets
• Familiarity with embedded firmware development (C/C++)
• Familiarity with common communication protocols (SPI, I2C, UART)
• Experience with PCB layout and design tools (we use Altium)
• Comfort with lab equipment including oscilloscopes, multimeters, and logic analyzers
• Interest in the underlying physics
• Enjoys applying creative, out-of-the-box solutions to reduce part count and complexity

Nice to have

• Bachelor's degree or higher in Electrical Engineering or related field
• Interest in RF system development and antenna design
• Deep knowledge of power management circuit design
• Ability to solder 0402 components by hand without frustration
