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 System Test is a ultra-fast-pace team responsible for pathfinding new hardware and delivering on environmental and durability campaigns for zipline's major hardware categories. The direct team is small and lightweight, and interacts with most departments at Zipline. You will be a technical leader in the small, special-ops team of test engineers and technicians across environmental, durability, and replicated-flight testing. You will own the system-test roadmap for reliability validation and rapid fault finding, and develop hardware and software to replicate in-flight stresses and to monitor the vehicle. The algorithms used for failure-detection can also be deployed to the fleet for fleet-wide monitoring. This team, and the fast discovery of hardware faults, is core to the success of Zipline and the velocity of hardware development and deployment. What You'll Do Develop novel ways of replicating in-flight environments on the ground, including external factors (dust, ingress, icing), and internal vehicle stresses. Deeply understand the vehicle DFMEA and own the vehicle actuation during system test. Translate mission profiles into qualification and life-test plans, including accelerated test design, stress levels, and sample size justification. Stay ahead of aircraft profiles and load curves, to help unlock new capability. Develop health monitoring and anomaly detection software (Python, Rust) for aircraft and robotic systems, with emphasis on using the vehicle's on-board telemetry. Drive the 'rapid failure finding' branch of the system test campaigns, a core input to design cycles and achieving maintenance goals. Build data pipelines and automated analysis tooling to adapt flight-software validators for system tests. Drive or develop directly the features needed in flight code to enable 'Test Mode' functionality. Integrate off-board sensors (cameras, airspeed sensors, other instrumentation) for continuous monitoring of vehicle health and tester health during long-duration tests. Conduct characterization of test assets, including developing analytical models and running instrumented test campaigns, to correlate test conditions to flight. - Drive decisions about test strategy overall: what new features are needed in system test, what should be tested at the system-level vs. component level vs. flight test. How to bring more coverage into system tests, and ways of rapid failure-finding. - Collaborate with the Reliability team to hone the strategy of long-duration vs. multiple vehicles being tested, as a function of the part-to-part variability and overall CapEx strategy. What You'll Bring Demonstrated experience leading test engineers, equipment designers, and technicians for complex hardware programs. Experience planning and running environmental, durability, and reliability test campaigns that inform engineering decisions. Experience in reliability techniques including MTBF, Weibull analyses, and DFMEAs. Strong electromechanical skills in embedded controls, real-time compute, and actuation. Software proficiency (Python, Rust, C/C++) Electrical engineering fundamentals including battery systems, communications protocols, and RF systems. Strong hardware-debugging intuition and electrical troubleshooting skills for aircraft or similarly complex electromechanical systems.- Sound judgment to prioritize test capability, campaign scope, and fault investigations across multiple hardware programs. Excellent ability to 'get unstuck' and make progress in a complex and changing environment. Experience developing real-time controls in safety critical applications.

.. Voluntary Self-Identification - Veteran Select... If you believe you belong to any of the categories of protected veterans listed below, please indicate by making the appropriate selection. As a government contractor subject to the Vietnam Era Veterans Readjustment Assistance Act (VEVRAA), we request this information in order to measure the effectiveness of the outreach and positive recruitment efforts we undertake pursuant to VEVRAA. Classification of protected categories is as follows: A "disabled veteran" is one of the following: a veteran of the U.S. military, ground, naval or air service who is entitled to compensation (or who but for the receipt of military retired pay would be entitled to compensation) under laws administered by the Secretary of Veterans Affairs; or a person who was discharged or released from active duty because of a service-connected disability. A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service. An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense. An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985. Voluntary Self Identification - Disability Select... Voluntary Self-Identification of Disability Form CC-305 Page 1 of 1 OMB Control Number 1250-0005 Expires 04/30/2026 Why are you being asked to complete this form? We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years. Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor's Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp . How do you know if you have a disability? A disability is a condition that substantially limits one or more of your "major life activities." If you have or have ever had such a condition, you are a person with a disability.
