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.
About You & the Role
We are hiring a Manufacturing Test Engineer 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 expected 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, with an onsite-first approach and regular factory-floor presence. Travel to other Zipline sites or vendor locations may be required for launches and validations.
What You’ll Do
Own assigned electrical, functional, and automated production testers and calibration stations from requirements through internal or vendor build, installation, validation, production release, and sustainment for aircraft, docks, delivery pods, and subassemblies.
Define test coverage, pass/fail limits, golden-unit strategies, GR&R, capability targets, and release criteria with Design, Firmware, Quality, and Operations.
Integrate harnesses, DAQ, sensors, actuators, power systems, safety interlocks, and mechanical fixtures to meet throughput and cycle-time needs.
Build automation and data pipelines using Python, LabVIEW/TestStand, or equivalent tools for reproducible execution, data logging, MES/MFG integration, and dashboards.
Troubleshoot production escalations on the factory floor under time pressure, including PCBA-level electrical failures, tester instability, fixture issues, software bugs, and product/tester correlation. Distinguish product defects from measurement or tester problems and validate corrective changes before release.
Improve first-pass yield, false-fail rate, tester uptime, utilization, and per-unit cycle time; set targets and report progress…
