Systems Modeling & Optimization Intern (Summer 2025)

About Zipline

Zipline is on a mission to transform the way goods move. Our aim is to solve the world’s most urgent and complex access challenges by building the first instant logistics system that serves all humans equally. Leveraging expertise in robotics and autonomy, Zipline designs, builds, and operates a fleet of cutting edge, autonomous delivery drones. We serve tens of millions of people around the world.

Joining Zipline’s Emerging Talent program as an intern is an opportunity to contribute to our promise of building a system that provides equitable access to critical healthcare supplies for millions of people. We believe that internships are more than just opportunities to learn by watching or doing low level tasks. We expect our interns to take on meaningful work that actively contributes to moving Zipline’s mission forward, while learning real-world skills that will serve them in their careers for the long term. 

Join us, and build the future of logistics with the best humans around!

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. mechanical, aerodynamics, electrical, battery chemistry, thermal, 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.

What You'll Do  

• Build physics-based models that underlie aircraft performance simulations
• Develop computational tools to automate high-level design trades, optimizations, and sensitivity studies
• Analyze test data to validate vehicle component models
• Devise frameworks for optimizing high-level control strategies

What You'll Bring 

• A drive to help people and make the world a better place
• Passion for tackling challenging multidisciplinary problems
• A strong grasp of classical physics
• The ability to recognize and model interactions between physical components and subsystems
• Expertise in Matlab, Python, Julia, or similar, for modeling, simulation, optimization, and/or data analysis

Nice to have:

• Basic understanding of batteries, electric motors, and/or aircraft dynamics; and typical approaches to modeling them
• Proficiency in numerical methods 
• Experience interpreting experimental data
• Experience with model-based systems design, ideally in an extracurricular setting
