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. About You and The Role The hardware test environment is a multi-disciplinary team responsible for building and maintaining Zipline’s engineering prototype fleet.

As a Test Technician, you’ll play a key role in validating new designs, building and maintaining tester equipment, and providing rapid feedback to engineering teams. This is a highly hands-on role that requires a strong background in assembly, troubleshooting, and instrumentation, along with the ability to clearly communicate issues and propose improvements that increase reliability and efficiency. This role is 100% on-site at our South San Francisco office, 5 days per week.

What You'Ll Do

Build and test prototype hardware across a wide range of maturity levels, providing manufacturability and efficiency feedback to engineering teams. Assemble, commission, and maintain tester equipment used to validate new hardware. Instrument test articles with sensors and data acquisition systems, ensuring accuracy and repeatability of results.

Collaborate closely with hardware teams to identify issues, troubleshoot failures, and develop solutions. Proactively flag risks, inefficiencies, or opportunities for process improvements, and help implement changes. Design and prototype fixtures to support builds, tests, and maintenance tasks.

Manage multiple hardware builds through various stages of mechanical and electrical testing. What You'll Bring Over 3 years of industry experience Experience with prototyping, assembly, or manufacturing of electro-mechanical systems. Hands-on skills in instrumentation (sensors, DAQ, wiring, calibration) and troubleshooting test setups.

A high level of craftsmanship, attention to detail, and ability to deliver quickly under time pressure. Strong communication skills, with the ability to clearly explain technical challenges and tradeoffs. A mix of skills such as soldering, harnessing, machining, technical documentation, or data analysis.

Bonus if you have: Familiarity with test automation or scripting (Python, C++, or similar). Ability to create or modify simple CAD models.

Requirements
