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 Zipline operates autonomous delivery systems that move critical goods through real-world airspace and logistics environments.

As a Senior Flight Test Engineer you will lead comprehensive flight test campaigns and integrate automated testing infrastructure into our flight test program. In this role, you will develop a deep understanding of Zipline’s end-to-end logistics system and work closely with cross-functional partners to generate rapid insights into changes across hardware, software, and operations. Your work will serve as the final line of defense before software or hardware are deployed globally to perform critical real-world deliveries.

You will own system-level flight test campaigns from planning through execution and analysis. This role is ideal for someone who enjoys translating complex engineering questions into effective test programs and using data and automation to accelerate learning.

What You'Ll Do

Develop and lead end-to-end flight test campaigns validating aircraft performance, delivery and pick up operations, docking systems, and fleet orchestration. Define system-level objectives, success criteria, and test plans with mechanical, electrical, software, systems and operations partners. Assess hardware and software readiness, evaluate risk posture, and make flight-readiness decisions before test execution.

Analyze flight data to identify anomalies, trends, and opportunities for continuous improvement. Produce deployment-readiness recommendations and prioritized corrective actions from campaign evidence. Build and integrate automated test tooling that improves test precision, insight, capacity, and velocity.

What You'll Bring 3+ years designing, developing, or validating autonomous robotic systems; UAS experience is preferred. Strong ability to analyze and interpret large test data sets for engineering decisions. Experience bringing up and debugging hardware and software systems for automated platforms.

Systems-level reasoning across structures, aerodynamics, embedded systems, and software. Sound judgment about when to move quickly with pragmatic solutions and when to invest in durable infrastructure, process and tooling. Experience maintaining and enforcing safety in a fast-paced, rapidly evolving environment.
