Prototype Engineer - 3D Printing

About 1XWe're an AI and robotics company based in San Carlos, California, on a mission to build a truly abundant society through general-purpose robots capable of performing any kind of work autonomously. We believe that to truly understand the world and grow in intelligence, humanoid robots must live and learn alongside us. That's why we're focused on developing friendly home robots designed to integrate seamlessly into everyday life. We're looking for curious, driven, and passionate people who want to help shape the future of robotics and AI. If this mission excites you, we'd be thrilled to hear from you and explore how you might contribute to our journey.About the TeamThe Hardware Prototyping Team provides the 3D printing, prototyping capabilities, and shared lab space that help bring NEO to life. Engineers need more than access to a printer. They need a reliable place to build, test, and iterate, with the right tools, materials, and hands-on support ready when they need them. Keeping that space running at an exceptional standard is central to how the team supports development.Your CharterYour charter is to keep the engineering team unblocked. You are the first point of contact for our 3D printing and prototyping lab and own the space, its equipment, and its day-to-day operation. Engineers should have everything they need to get straight to work. The lab is spotless, organized, fully stocked, and ready to use, and keeping it that way is on you.Key OutcomesBe the first point of contact for engineers using the lab, understand what they need, and coordinate printing requests and hands-on prototyping supportDeliver 3D printing support start to finish, from file preparation and printing through post-processing and part handoverSet and maintain an exceptional standard for the space. Workbenches are spotless, tools have a home, and equipment is ready to useOwn the lab: stock, ordering, tooling, maintenance, organization, and safe working practices. Anticipate engineers' needs and close gaps in tools, materials, and prototyping capabilitiesKey CompetenciesA builder who owns problems end-to-end and takes personal responsibility for whether the team is blockedA practical, approachable first point of contact who enjoys helping engineers and follows requests through to completionOrganized by instinct.
