Mechanical Engineer Intern (Summer 2027)

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. The Role Does aggressively tackling cross disciplinary projects from early conceptual stages through to full field deployment sound like the way you want to spend your time? Do you eliminate circular discussions by running a test or use your hands-on skills to build a prototype instead of scheduling another meeting? At Zipline, your work is intended for the field, where customers are counting on it every day, so there is no time for ambiguous communication or unrealistic expectations. We need dedicated engineers to burn down risk and improve reliability in our system like their life depends on it– because others' lives do. If you thrive working with a fast-paced and driven team that focuses on only the most important goals, eliminates blockers, and executes with extreme practicality, keep reading! Mechanical Engineers at Zipline go deep in their area of ownership, become experts in the problem domain, define requirements for their systems, rapidly develop creative and simple solutions, and prove with testing that their system meets the rigors and edge-cases of real-world deployment. We are composed of teams that are responsible for everything from the earliest designs of a new system, to creating test and validation strategies, root-causing issues with existing systems, and much more. What You'll Do Mechanical interns can own a variety of big problems integral to our system! You can expect to:Take product and engineering requirements to develop concepts and evaluate tradeoffs for eachUse 2D and 3D CAD tools to design parts and assemblies based on sound engineering principlesUse resources creatively to design, build, and test prototypes to gather quick learningsWork cross-functionally with other Zipline teams and suppliers to review designsDesign, build, and run electro-mechanical testers that you develop to prove reliability of critical componentsEvaluate designs and components on a material, element, and fully integrated product level Root cause failures and develop a test to replicate the failure modeDocument your work so that others can easily understand key decisions madeExamples of previous intern projects include designing, building, testing, and running: flexible blind-mate ducting connection between an aircraft and a ground-based cooling station, allowing for aircraft battery temperature regulation during charging and pre-flight preparationa service strategy for removing a docked aircraft from a ground station using a custom designed hand cart, complete with an ergonomic study for a range of technician heights and strengthsa communications tower with integrated antennas and lightning protection meant to relay vital telemetry information from the drone to the operators during flightcharacterization of proposed and delivered materials, and properties (static strength, durability, and dynamic response) of configured structuresa wing cycle tester to identify and eliminate risk for each wing iteration and prove reliability with cycles What You'll Bring The most critical skill we’ve seen in prior entry-level candidates is robust experience designing and actually building multiple mechanical systems outside of the classroom. This is the component of your application we’re most excited about, so please ensure that you’ve included this work in your application. Examples of things previous interns have built include submarines, solar cars in the Australian outback, electric boats and airplanes, rockets, etc. You must have completed at least the second year of your Undergraduate studies. Masters and PhD students are also eligible. You’ll bring solid mechanical engineering fundamentals for structural analysis, sizing parts, and integrating components into a design with minimal helpYou’ll bring automation experience from working with actuators and Raspberry Pi’s (or similar)You’re well versed in CAD, and have designed multiple projects with itYou’ve worked on complex projects that require mechanical, electrical, and software designYou're quick to change direction when you realize you’ve made a mistake OR could achieve the same goal in a simpler wayYou bias to action and communicate consistently with your team to ensure everyone is focused on meeting the project goals on timeYou're excited to build on your design skills with brainstorms, design reviews, and failure mode analysisYou can anticipate, plan and schedule your own workYou bring a “can do” attitude, because we have a lot of vital work to get done and only work with people who are invested in solving critical problems What Else You Should Know Our internships are full-time positions, in-person at our South San Francisco or Dallas office. We will host our Summer 2027 interns from May/June to August/September. Candidates are limited to three (3) applications within a 30-day period.
