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 Team The 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 Charter Your 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 Outcomes - Be the first point of contact for engineers using the lab, understand what they need, and coordinate printing requests and hands-on prototyping support - Deliver 3D printing support start to finish, from file preparation and printing through post-processing and part handover - Set and maintain an exceptional standard for the space. Workbenches are spotless, tools have a home, and equipment is ready to use - Own the lab: stock, ordering, tooling, maintenance, organization, and safe working practices. Anticipate engineers' needs and close gaps in tools, materials, and prototyping capabilities ## Key Competencies - A builder who owns problems end-to-end and takes personal responsibility for whether the team is blocked - A practical, approachable first point of contact who enjoys helping engineers and follows requests through to completion - Organized by instinct. Cleanliness, inventory, documentation, and lab discipline stay tight without anyone reminding you - Moves fast with high standards, holding quality and safety sacred even at velocity ## Minimum Requirements - Hands-on experience with 3D printing and prototyping, or equivalent trade or technician experience. - Proficiency in print preparation, printer operation, troubleshooting, and post-processing - Ability to work from CAD files and engineering drawings - Comfortable using common workshop tools and supporting engineers with practical prototyping tasks - Experience keeping a shared lab or workshop organized, stocked, and ready to use - Working knowledge of safe lab practices, equipment care, and material handling ## Preferred Skills - Experience with robotics, actuation systems, or other tightly integrated electromechanical products - Experience with Multi Jet Fusion (MJF) printing - Experience maintaining 3D printers and shared prototyping equipment - CAD literacy for simple part modifications and quick-turn lab tooling - Other fabrication skills that shorten the loop on lab tooling What does a successful 1X Team Member look like Team members at 1X who thrive here are builders. They move fast, own their work completely, and treat time like it's the one thing you can't get back - because it is. They say what they mean, finish what they start, and hold themselves to a standard before anyone has to ask. We push each other to be better, and we do it with honesty and respect. ## Compensation Range $100,000 - $130,000 + Equity ## Benefits - Comprehensive medical, dental, and vision coverage - Generous paid time off, company holidays, and parental leave - 401(k) plan with company match (100% on the first 3% of contributions, 50% on the next 2%) - Flexible Spending Accounts (FSA) and Health Savings Accounts (HSA) options - Commuter benefits (transit and parking) - Short-term and long-term disability, and life insurance - Employee Assistance Program (EAP) for mental health, financial, and personal support - Onsite snacks and catered lunches ## Equal Opportunity Employer 1X is an Equal Opportunity Employer.
