Prototype Technician - New Products

Telemetry Today LLC; South San Francisco (CA); On-site; USD 70,000 - 100,000; Full time

Job summary

Zipline in South San Francisco, CA is seeking a Prototype Technician to create hardware that has never existed before. You will work with engineers and designers to translate concepts into physical prototypes, with significant autonomy in choosing how to build and improve designs.

You’ll fabricate, assemble, test, and refine electromechanical systems, from cardboard mockups to flight-quality prototypes, applying broad hands-on skills and disciplined documentation throughout.

Qualifications

• Broad hands-on fabrication across machining, welding, composites, electrical harnessing, soldering, additive manufacturing or sheet-metal fabrication.
• Strong mechanical intuition and ability to troubleshoot unfamiliar electromechanical hardware.
• Ability to work from incomplete drawings or early concepts to build and test hardware.

Responsibilities

• Build first-of-their-kind prototypes for aircraft, mechanisms, electrical systems, ground equipment, and experimental hardware.
• Translate sketches, CAD, and early engineering concepts into functional hardware using appropriate materials and processes.
• Create mockups and flight-quality assemblies, selecting the level of fidelity needed to answer each design question.
• Fabricate mechanical parts and composite structures using machining, welding, sheet metal, hand tools, additive manufacturing, and prototype tooling.
• Assemble, troubleshoot, modify, and repair complex electromechanical systems, including harnesses, sensors, actuators, motors, and connectors.
• Instrument prototypes with sensors, wiring, DAQ systems, and measurement equipment; support testing, diagnose failures, and implement improvements in subsequent builds.
• Document builds, configurations, repairs, failures, and lessons learned; provide feedback on manufacturability, assembly, serviceability, reliability, and design simplicity.

Job description

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’s New Products team invents our next generation of systems. We’re looking for exceptional prototypers and makers who can help turn new ideas into real hardware and enable entirely new aircraft capabilities. We work across aircraft, mechanisms, electrical systems, ground equipment, and experimental test hardware.

Your role is to create hardware that has never existed before. You are equally comfortable building a rough mockup from cardboard and 3D prints, fabricating a flight-quality prototype, debugging a mechanism, repairing a composite structure, or troubleshooting a wire harness. Designs evolve quickly, and the fastest path to learning is often to build something, test it, understand what failed, and build the next version.

As a Prototype Technician, you will work closely with engineers and designers to translate concepts into physical prototypes. You will have significant autonomy in deciding how to build things, what tools and processes to use, and how to improve designs as you uncover problems.

What You’ll Do

• Build first-of-their-kind prototypes for aircraft, mechanisms, electrical systems, ground equipment, and experimental hardware.
• Translate sketches, CAD, and early engineering concepts into functional hardware using appropriate materials and processes.
• Create mockups and flight-quality assemblies, selecting the level of fidelity needed to answer each design question.
• Fabricate mechanical parts and composite structures using machining, welding, sheet metal, hand tools, additive manufacturing, and prototype tooling.
• Assemble, troubleshoot, modify, and repair complex electromechanical systems, including harnesses, sensors, actuators, motors, and connectors.
• Instrument prototypes with sensors, wiring, DAQ systems, and measurement equipment; support testing, diagnose failures, and implement improvements in subsequent builds.
• Document builds, configurations, repairs, failures, and lessons learned; provide feedback on manufacturability, assembly, serviceability, reliability, and design simplicity.

What You’ll Bring

• Broad hands-on fabrication experience across several disciplines, such as machining, welding, composites, electrical harnessing, soldering, additive manufacturing, or sheet-metal fabrication.
• Strong mechanical intuition and the ability to troubleshoot unfamiliar electromechanical hardware when failure modes are unclear.
• Ability to work from incomplete drawings or early concepts and independently determine the practical details needed to build and test hardware.
• Experience building and troubleshooting prototype electrical systems, including sensors, wiring, actuators, motors, connectors, or measurement equipment.
• Judgment to balance craftsmanship with learning speed, knowing when a rough prototype is sufficient and when a careful assembly is required.
• Clear communication and disciplined documentation of important changes, discoveries, and failures.
• Strong safety awareness around experimental aircraft, batteries, motors, machinery, and other high-energy systems; experience in aerospace, automotive, robotics, motorsports, or industrial equipment is a plus.
