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

The droid is the delivery container at the heart of our delivery system. It's what detaches from the aircraft on a tether, descends 300 feet, and places your order on a driveway, or picks up an order at a merchant's zipping point and returns to the aircraft. The interaction between the droid and the zipping point infrastructure is the most cycled, most reliability-critical mechanical interface in our system.

We're designing EV3, the next generation of the droid and the next versions of our ground pickup stations. As we scale toward thousands of units in production and tens of thousands of flight cycles per unit, we need someone to own the ground testing that makes that scale credible - every fixture, life-test rig, environmental chamber, and automated bring-up station that proves the droid and zipping point work reliably together while exceeding our reliability targets.

You'll join a small, deeply cross-disciplinary hardware team building and testing our future systems end-to-end.

What You'll Do
  • Own the ground test strategy for the droid and its interaction with zipping point infrastructure - from pickup and drop-off mechanics, to tether engagement, to environmental exposure of the mated system.
  • Design, build, and deploy custom mechanical test fixtures and life-test rigs, from concept through fabrication, bring-up, and long-duration operation
  • Develop the electrical and instrumentation side of these test systems. Load cells, thermocouples, encoders, current sensing, motor drivers, pneumatic actuators, DAQ, safety interlocks, etc.
  • Write the automation software that runs them - Python scripting, data logging, live health monitoring, automated pass/fail evaluation, integration into our broader hardware test framework.
  • Drive test campaigns from early prototype validation through qualification, life testing, and production end-of-line testing.
  • Triage and root-cause failures across mechanical, electrical, and firmware domains, using data, test heritage, and one-off targeted campaigns.
  • Partner directly with the mechanical, electrical, firmware, and manufacturing engineers designing EV3 - pushing back on requirements when the physics doesn't support them, and proposing changes when testing reveals opportunities to improve reliability.
  • Travel occasionally to suppliers and manufacturing partners (China, Malaysia, Japan, Italy, Germany, Vietnam) to deploy test equipment, qualify processes, and support production ramps.
What You'll Bring
  • BS or MS in Mechanical Engineering, Mechatronics, Robotics, or a related field, with 3+ years of hands-on experience delivering electromechanical hardware or test software.
  • Demonstrated ability to design mechanical hardware in a CAD environment (we use Siemens NX).
  • Comfort with the electrical side of test equipment - reading schematics, wiring up a fixture, debugging with a scope, selecting the right sensor for the job.
  • Real Python experience. You've written test automation, data processing scripts, or bench-top control software that other people relied on.
  • A systems approach to problem solving: a knack for identifying whether a failure lives in mechanics, electronics, firmware, or their interaction, and diving deep into whichever domain the problem lives in.
  • Strong fabrication and prototyping instincts - you're comfortable in a machine shop, with hand tools, and at a soldering station.
  • The judgment to know when a test is telling you something real vs. when the fixture itself is the problem.
Bonus points for any of the following:
  • Experience with high-cycle mechanical life testing, environmental chambers, or accelerated life test design
  • Firmware experience (C, C++, Rust) on microcontrollers driving test equipment
  • PCB design experience for custom fixtures or breakout boards (Altium, KiCad)
  • Prior work in drone, robotics, automotive, medical device, or consumer electronics NPI
  • Experience deploying test equipment to contract manufacturers and supporting production ramps

What you need to know about the Los Angeles Tech Scene

Los Angeles is a global leader in entertainment, so it’s no surprise that many of the biggest players in streaming, digital media and game development call the city home. But the city boasts plenty of non-entertainment innovation as well, with tech companies spanning verticals like AI, fintech, e-commerce and biotech. With major universities like Caltech, UCLA, USC and the nearby UC Irvine, the city has a steady supply of top-flight tech and engineering talent — not counting the graduates flocking to Los Angeles from across the world to enjoy its beaches, culture and year-round temperate climate.

Key Facts About Los Angeles Tech

  • Number of Tech Workers: 375,800; 5.5% of overall workforce (2024 CompTIA survey)
  • Major Tech Employers: Snap, Netflix, SpaceX, Disney, Google
  • Key Industries: Artificial intelligence, adtech, media, software, game development
  • Funding Landscape: $11.6 billion in venture capital funding in 2024 (Pitchbook)
  • Notable Investors: Strong Ventures, Fifth Wall, Upfront Ventures, Mucker Capital, Kittyhawk Ventures
  • Research Centers and Universities: California Institute of Technology, UCLA, University of Southern California, UC Irvine, Pepperdine, California Institute for Immunology and Immunotherapy, Center for Quantum Science and Engineering
