1x.tech
About 1x We’re an AI and robotics company based in Palo Alto, 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.
Role Overview We are seeking a Materials & Prototyping Lab Associate to join our research and development team. In this creative, hands‑on role, you’ll work at the intersection of materials science, physics, and robotics, supporting the development of next‑generation materials and processes for humanoid robots. You will collaborate closely with Ph.D. scientists and cross‑functional engineering teams to prepare samples, conduct experiments, and support materials discovery and rapid prototyping.
Responsibilities
Prepare, mix, and process materials including polymers, resins, adhesives, coatings, and textiles using lab‑scale mixing, roll mill processing, compounding, molding, and curing equipment
Conduct wet chemistry experiments such as functionalization, solution blending, polymerization, surface treatments, and solvent casting
Support scientists in designing and executing experiments that reveal new structure‑property relationships and functional performance
Characterize materials using mechanical, thermal, and microscopic analyses and organize data for review
Operate and maintain FDM, SLA/DLP, and SLS 3D printers, optimizing print quality and part consistency
Fabricate fixtures, jigs, and prototype assemblies for testing and development
Collaborate across mechanical, electrical, and materials teams to support rapid, iterative prototyping cycles
Maintain chemical inventory, MSDS documentation, and EHS compliance for materials labs
Ensure proper PPE use, fume hood operation, and waste‑handling procedures are followed
Keep lab instruments calibrated and workspaces organized for accuracy and reproducibility
Support a culture of safety, discipline, and continuous improvement within the materials lab
Requirements
Bachelor’s degree in Materials Science, Chemistry, Physics, Engineering, or a related field
1–3 years of hands‑on R&D laboratory experience (academic, industrial, or prototype lab)
Experience working in wet chemistry environments, including safe handling of solvents, polymers, and resins
Familiarity with 3D printing processes (FDM, SLA/DLP) and slicing/CAD tools
Strong mechanical aptitude and comfort assembling and testing small parts or prototypes
Familiarity with EHS systems and chemical hygiene programs
Excellent documentation, communication, and organizational skills
A self‑starter who is curious, proactive, and takes ownership in supporting the success of the Materials team
Experience with materials characterization tools (tensile testers, rheometers, thermal analyzers, microscopes)
Background in polymer, composite, or coating process development
CAD design experience (Fusion 360, SolidWorks, Onshape) for prototyping and fixture design
Experience with rapid prototyping using polymers, including part finishing and iterative design
Exposure to robotics, mechatronics, or advanced manufacturing environments
Benefits & Compensation
Health, dental, and vision insurance
401(k) with company match
Paid time off and holidays
