Flight Test Engineer Intern (Fall 2026)

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 the Flight Test Engineering Team Zipline’s Flight Test Engineering team is a specialized group that designs flight test courses and methods to support our overall system validation progress. This involves developing custom flight control software for complex maneuvers and collaborating with development engineers to design rigorous tests for all critical edge cases. We leverage expertise in system design, statistics, flight physics, and sound experimental methods to ensure our flight tests are effective and safe. The team partners closely with Controls and Dynamics, Embedded Software, Autonomy, Systems Engineering, Powertrain, Structure, and Flight Operations teams to build comprehensive test plans and test cards. Our work spans simulation, hardware testing, data-driven analysis, and system-level evaluations that support deployments across the globe. As an intern, you’ll collaborate with engineers across these domains, gaining hands-on exposure to how industry-leading autonomous systems are designed, tested, and validated at scale. The Role As a Flight Test Engineering Intern, you will be instrumental in analyzing flight test data logs to determine test effectiveness, identify success/failure root causes, and track performance trends. You will also directly contribute to the design of new flight test campaigns, collaborating with other engineers to define the test scope, test method, and data post-processing. This is a unique opportunity for someone excited to learn how complex robotic systems are validated, who enjoys problem-solving, and who wants to build real-world experience working with autonomy software, data analysis, and systems engineering. What You'll Do Analyze flight test data logs using custom scripts (Python, DataBricks, SQL) to identify anomalies, assess reliability, track performance trends, and perform regression analyses. Design, oversee the execution, and review the results of software validation and flight test campaigns to ensure new features perform as intended and prevent hardware/software regression. Daily test and monitor the develop branch to quickly surface instability and potential future issues. Collaborate with cross-functional partners (GNC, Aerodynamics, Structures, Systems Engineering) to ensure system-level requirements (e.g., acceleration, range, climb rate) are clear, measurable, and that vehicle changes are mature for flight te
