About Zipline

Zipline is the world’s largest and most experienced drone delivery service. We are on a mission to serve all humans equally by ensuring access to food, medicine and essential goods anytime, anywhere. We design, build, and operate the world’s largest autonomous logistics system, delivering critical supplies quickly and reliably. Today, Zipline operates on four continents, makes a delivery somewhere in the world every 30 seconds, and has completed millions of deliveries to date, including blood, vaccines, medical supplies, food, and retail products.

Our customers include the world’s largest and most prominent healthcare systems, governments, retailers, restaurants and global businesses who rely on us to save lives, reduce emissions, increase economic opportunity, and provide delivery from point A to point B as fast as possible. The drone is only 15% of what we’ve built to enable seamless, reliable, global operations.

Our system strengthens supply chains, reduces congestion, and gives people time back. With more than 140 million commercial autonomous miles safely flown, Zipline is redefining access to healthcare, consumer products, and food across the globe.

We operate at a global scale and are looking for practical problem solvers who thrive on real‑world challenges and rapid growth. Our team is motivated by building systems that have a direct, meaningful impact on people’s lives and by scaling the future of logistics. We are seeking people who sculpt from first principles, enjoy facing adversity, and can do the impossible at record‑breaking speeds.

Zipline builds autonomous delivery aircraft and ground systems that operate daily in varied field conditions. Reliable products begin with reliable validation. As an Electromechanical Test Equipment Design Engineer, you will own the design and development of the test systems that enable engineers to characterize, validate, qualify, and manufacture battery and power electronics hardware with confidence.

The Battery & Power Electronics team is responsible for delivering power throughout the aircraft—including batteries, power distribution systems, busbars, and power connectors. You will develop custom test equipment integrating mechanical design, electrical hardware, instrumentation, controls, automation, and software to create robust, scalable systems that accelerate product development and generate accurate, repeatable engineering data.

This role is open to engineers at all levels. Responsibilities and scope will scale with experience—from owning individual fixtures and subsystems to leading the architecture and strategy for complex validation infrastructure spanning multiple aircraft programs.
