About You and The Role Zipline builds autonomous delivery systems that move essential goods.

As a Maintenance Operations Engineering Technician in Esparto, California, you will keep prototype flight vehicles, ground infrastructure, and test equipment safe, configured, and ready for engineering development and field operations. You will own hands-on maintenance and test execution: replacing components, preparing vehicles and test setups, running endurance campaigns, and isolating first-order issues. Your work enables safe test execution, reliable data capture, accurate configuration records, and evidence engineers use for design and vehicle-readiness decisions.

This role is based on site in Esparto, California, with flexibility required to support testing operations at other locations across the United States.

What You'Ll Do

Maintain prototype aircraft, ground infrastructure, and test equipment to keep approved test campaigns executable and vehicles available for engineering work. Replace vehicle components, perform checkouts, and maintain complete maintenance documentation and configuration records. Execute semi-automated vehicle checkouts, reliability campaigns, and endurance tests using documented procedures and repeatable setups.

Prepare test articles, equipment, instrumentation, and data-acquisition systems so test specifications can be executed as written.

Requirements

before test execution. Independently isolate and document first-order test-system or test-article faults; surface deviations and escalate root-cause resolution to engineers. Produce test reports that connect observations and data to reliability improvements, design iterations, and vehicle-readiness decisions.

Travel to support testing, maintenance, and operational needs at other Zipline locations across the United States. What You'll Bring Experience operating common machine-shop equipment and building mechanical assemblies, fixtures, jigs, or test hardware. Hands-on experience with electrical and electronic assemblies across different power levels and component sizes.

Experience setting up, instrumenting, executing, and documenting hardware or hardware/software tests alongside engineers.
