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 builds, manufactures, and operates autonomous delivery systems that move critical goods where they are needed.

The Controls team develops the models, tools, and flight software foundations that allow aircraft to complete missions autonomously across changing conditions. As a Staff Controls Engineer, you will own system-performance analysis for vehicle designs and help turn flight and fleet data into better models, design decisions, and operational capability. You will work closely with controls, flight test, hardware, manufacturing, and customer-facing teams to identify where performance limits matter most and drive technical improvements.

What You'Ll Do

• Own dynamic models of complex vehicle systems and components within Zipline’s high-fidelity six-degree-of-freedom simulation. • Build controls algorithms that are robust, performant, fault tolerant and own the development, testing, analysis and deployment of the same.

Requirements

, limitations, and environmental conditions to vehicle performance. • Evaluate existing and future vehicle designs through simulation, flight-test data, and data from customer aircraft in the global fleet. • Improve simulation fidelity by reconciling model predictions with observed flight behavior and identifying the highest-value gaps.

• Lead technical recommendations for controls, vehicle, and system design improvements with software, hardware, flight test, and manufacturing partners. • Build reusable analysis tools that enable teams to investigate performance questions, compare design options, and make informed tradeoffs. • Translate operational and customer insights into engineering priorities that improve the reliability and capability of the logistics network.

What You'll Bring • Demonstrated expertise in controls, flight dynamics, system identification, or modeling of complex physical systems. • Experience developing and using high-fidelity simulations to evaluate system performance and guide engineering decisions. • Experience analyzing experimental or flight-test data and using evidence to validate models or improve designs.

• Ability to lead ambiguous technical problems from framing through analysis, recommendation, and cross-functional execution.
