About You & the Role
We are hiring a Mechatronics Engineer, Production Test to own electrical, functional, and automated test systems that verify Zipline aircraft, dock, delivery pod, and subassembly hardware at scale. Zipline operates safety-critical autonomous aircraft and logistics systems that deliver medicine and essentials across varied field conditions; production test directly affects fleet uptime, field reliability, and customer deliveries. In this role you will lead end-to-end test system delivery for factory floors that support high-throughput manufacturing and rapid product iterations. You will be expevcted to prioritize safety, traceability, and measurable improvements in yield and time-to-deploy while working in a fast-scaling production environment with direct consequences for aircraft reliability and delivery network performance.
This opening sits within our manufacturing engineering team; the exact focus will reflect your strengths and the team’s needs. This role is based at Zipline’s South San Francisco manufacturing site (onsite-first with regular floor presence); travel to other Zipline sites or vendor locations may be required for launches and validations.
What You’ll Do
Build electrical and functional testers that integrate harnessing, DAQ, sensors, actuators, power systems, safety interlocks, and mechanical fixtures.
Own production testers and calibration stations from requirements through internal or vendor build, installation, validation, release, and sustainment.
Define test coverage, pass/fail limits, golden units, GR&R, capability targets, and release criteria with design, firmware, quality, and operations partners.
Implement test automation and data pipelines for repeatable execution, logging, MES/MFG integration, and production dashboards.
Troubleshoot PCBA failures, tester instability, fixture issues, software defects, and product/tester correlation failures on the factory floor.
Improve first-pass yield, false-fail rate, cycle time, uptime, and utilization; set targets and report progress monthly.
Coordinate vendor builds, FAT/SAT, qualification, training, calibration, spares, and change control.
Standardize tester interfaces and automation to reduce operator steps and touch time; maintain procedures, validation records, and maintenance plans for traceable production.
