Embedded Electrical Engineer Intern - Flight Hardware

WindBorne Systems; Redwood City (CA); On-site; USD 41,000 - 50,000; Full time

Job summary

WindBorne Systems in Redwood City, CA is seeking an Embedded Electrical Engineer to design, bring up, debug, and support flight hardware and ground systems for our balloon constellation.

You will iterate quickly on PCBs, develop firmware in C/C++, read schematics, and work with mechanical engineers to ensure rugged performance from -70°C to +40°C, while chasing rapid, reliable delivery.

This role rewards hands-on bench work, fast problem-solving, and shipping hardware on tight timelines.

Qualifications

• 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 (Altium).
• Comfort with lab equipment including oscilloscopes, multimeters, and logic analyzers.

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.
