Embedded Software Engineer Intern (Spring 2027)

Zipline is a drone delivery service that designs, builds, and operates autonomous logistics systems to deliver critical supplies. The Embedded Software Engineer Intern will join the Embedded Systems team to develop solutions for autonomous aircraft and ground systems, including safety-critical embedded software, firmware, testing, perception systems, and operational improvements.

What you'll do:

• Building an RF radio test setup to validate antenna performance of the flight compute at the production end-of-line. Responsibilities include owning the entire system—from RF signal injection, testing, and validation, to developing manufacturing software test suites, integrating with Hardware-in-the-Loop (HIL), and leveraging simulation to model and measure worst-case scenarios
• Develop firmware for a real-time coprocessor that manages high-frequency signals and I/O expansion for the Linux camera subsystem. Own the overall system design, contribute to board design revisions, and validate signal integrity, jitter, and clock alignment
• Building a high data rate voltage and current telemetry system that runs continuously in our RTOS using ADCs, I2C devices and GPIO interrupts. Testing this feature rigorously, deploying it to production globally, building data analysis tools to verify that the feature is working properly, and using this data to root-cause tricky failures to improve the reliability of our systems
• Rapidly iterating on the concept of a new perception system, integrating compute modules and sensor prototypes to fly a proof of concept ASAP and de-risk key aspects of the approach
• Working with operations teams to identify ways to improve our ground systems behavior to enable faster aircraft launch and landing. Prioritizing changes by obtaining engineering leadership buy-in, and implementing them by using a variety of bench-top and real flight-test methods to verify the code. Ultimately, rolling out the update to global operations!

What they're looking for:

• Pursuing a degree in Electrical Engineering, Computer Science, or Computer Engineering. Must have at least completed the second year of your Undergraduate studies. Masters and PhD students are also eligible
• You've designed, built and/or deployed electromechanical systems or robots, inside or outside the classroom
• You're comfortable working in one of C, C++, Python, or Rust, and have developed software for a real time operating system or embedded Linux
• You are comfortable receiving feedback so that you can learn to write code that is efficient, easy-to-read, well-tested, has friendly APIs, and incurs minimal technical debt
• You're familiar with basic electrical engineering concepts, such as reading schematics, debugging with an oscilloscope, and communication protocols (CAN, SPI, UART, etc)
• This internship is a full-time position, in-person at our South San Francisco office. We will host our Spring 2027 interns from (January 2027 - April 2027)

Benefits:

• Relocation support
• A housing stipend
• Overtime pay
• Paid sick time
