Computational Physics Intern; Fall

About the Systems Modeling Team

The Systems Modeling Team has tremendous power to shape Zipline’s products. We develop physics‑based models and use them to architect our aircraft, as well as the supporting logistics system. Using simulation, we can rapidly explore a vast array of designs to optimize future products, and we can find ways to squeeze more performance out of our existing products.

Systems Modeling brings diverse teams and fields together (e.g. electrical, thermal, mechanical, aerodynamics, battery chemistry, controls, fleet operations, economics) to gain new insights. We translate technical conversations into rigorously framed engineering problems. We value asking pertinent questions and generating coherent answers.

Leading the way in drone delivery requires pushing the limits of individual component technologies and carefully orchestrating which ones we put together to optimize the performance of the complete vehicle. How much of the benefit of a larger motor is counteracted by its aerodynamic penalty? How much range are we willing to give up for extra payload capacity? How do we optimally control battery charging – electrically and thermally – to strike a balance between turnaround time and battery longevity?

Answering these types of questions requires high‑caliber computational tools. Zipline is seeking an engineering intern that can understand system‑level problem statements, appreciate the trade‑offs between accuracy and computational efficiency, and architect elegant code tools. The outputs of these tools will directly drive critical architectural and operational decisions at the aircraft and fleet level.
