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.

About You and the Role

Does quickly developing multiple iterations of systems to test novel components through the extreme environments demanded of aerospace applications sound like the way you want to spend your time? Do you love designing tests for cross-functional interfaces with little information, full ownership, and the responsibility to make it happen? At Zipline our work is intended for the field. Patients are counting on it today--there is no time for aiming low or coming up short. If leveraging your talent to drive full vehicle test systems to fruition with a small but dedicated team at your side sounds like your cup of tea, please read on.

Zipline is at the forefront of a logistics revolution: We design, manufacture, and operate our own fleet of autonomous drones to make deliveries of supplies to people in need within minutes, 7 days a week. 

We are hiring Mechanical Test Engineers across three different teams; Ground Systems, Structures & Mechanisms, and Powertrain & Battery. We are a hardware engineering organization with Mechanical, Electrical, Embedded Systems and Test Engineering and are responsible for the design of all flight hardware and operations equipment; this includes Safety Systems, Primary Structure, Launcher, Recovery System, Battery Chargers, Power System, Network System and countless other mechanisms critical to the function of the vehicle and ground systems. We are working on a product that can be deployed in hours, integrate seamlessly with our customers, and operate without human intervention while being deployed worldwide at scale.

What You'll Do

As a member of the Test Team you will be responsible for cradle-to-grave design and implementation of systems used to develop and prove concept functionality and key reliability metrics on the Zipline systems. You will be directly responsible for creation of several major test systems, some of which are well defined, and others which will require you to do critical analysis of what our customers want and what it will take to WOW them before embarking upon the design process.  To accomplish this you will need to do the following:

  • Work with the product design and reliability teams to generate requirements for test systems that accurately capture the intended function of the vehicle while leaving the door open for future automation and high volume capacity.&l
