Hardware Intern Jobs in California (NOW HIRING)

The Long Range Platform Design Engineering team is responsible for designing, testing, and continuously improving the hardware that makes up Zipline's long-range autonomous delivery aircraft. We own hardware across the aircraft, from structures and mechanisms to electromechanical systems, taking designs from early concepts and prototypes through validation, production, and operation in the field. Our engineers work hands-on and cross-functionally, partnering closely with teams across Test, Manufacturing, Supply Chain, and Operations to solve challenging multidisciplinary problems. We focus not just on making hardware that works, but on making it reliable, lightweight, manufacturable, maintainable, and capable of performing day after day in demanding environments. By improving the performance and reliability of our aircraft, our team directly enables Zipline to deliver critical goods safely and consistently at global scale. What makes our team special is the breadth of ownership: you can take an idea from a sketch or CAD model, build and test it yourself, and ultimately see it flying in a system serving customers around the world.

As a Hardware Engineering Intern on the Long Range Platform Design Engineering team, you'll take ownership of real hardware challenges that directly impact the performance, reliability, and scalability of Zipline's long-range delivery system. You'll have the opportunity to take a project from understanding the problem and developing concepts through building, testing, and iterating on real hardware. Your work won't live on a shelf—you'll see how the decisions you make contribute to aircraft that operate every day and help Zipline expand access to essential goods around the world. Along the way, you'll work closely with experienced engineers and collaborate with teams across the company, learning how complex hardware goes from an idea to a reliable product operating at scale. This is an opportunity to build your engineering judgment, get your hands dirty, and make a meaningful contribution to a system with real-world impact.

• Own a focused hardware design project or root-cause investigation from problem definition through a tested solution.
• Develop mechanical and/or electrical designs using engineering fundamentals, CAD, and analysis.
• Build and iterate on prototypes, test fixtures, and hardware using hands-on fabrication and assembly.
• Design and run tests to characterize performance, investigate failures, and validate solutions.
• Analyze test data to identify root causes, evaluate tradeoffs, and make engineering decisions.
• Collaborate with experienced engineers across disciplines and learn how complex hardware is developed and deployed.
• Communicate your work through design reviews, test results, and technical documentation.

• Pursuing a Bachelor's degree in Mechanical Engineering, Electrical Engineering, or a related field, ideally in your junior or senior year.
• Strong understanding of core engineering fundamentals and an ability to apply them to open-ended hardware problems.
• Experience building, testing, or troubleshooting physical systems through coursework, project teams, research, internships, or personal projects.
• Comfort working hands-on with prototypes, tools, test equipment, and basic fabrication or assembly.
• Ability to analyze data, identify likely root causes, and clearly communicate your reasoning.
• Curiosity, ownership, and a willingness to learn quickly from both successes and failures.
• Ability to work onsite and collaborate closely with engineers in a hands-on hardware development environment.

Our internships are full-time positions, in-person at our South San Francisco office. We will host our Summer 2027 interns from May/June 2027 to August/September 2027. This position is also open to Spring/Summer co-ops.
