Materials Planner

1X • San Carlos, CA

35d • $100,000 - $120,000 • Hybrid

About The Position

1X is building humanoid robots that work in any space humans exist with the mission to create an abundance of labor. This role is within the Supply Chain team, which ensures that every part NEO (their flagship robot) needs is in the right place, at the right time, and in the right quantity as the company moves from building robots to shipping them at scale. The Materials Planner will own the material plan that keeps NEO production running by translating the build schedule into a reliable, time-phased supply plan for their commodities. The goal is to ensure the right parts arrive exactly when they are needed, preventing production line stoppages due to shortages and avoiding excess inventory that ties up cash during production ramps.

Requirements

• 3-5 years of materials planning, production planning, or supply planning experience in a manufacturing environment (hardware, electronics, automotive, aerospace, or similar).
• Bachelor's degree in Supply Chain, Operations, Industrial Engineering, Business, or a related field, or equivalent practical experience.
• Hands-on experience running MRP in an ERP system (e.g., NetSuite, SAP, Oracle).
• Advanced Excel / Google Sheets skills (pivot tables, lookups, building planning models).
• Working knowledge of BOM structures, lead-time management, and inventory control fundamentals.
• MRP fluency and systems thinking: understands how BOMs, lead times, lot sizing, and safety stock interact, and can spot when the system is wrong.
• Proactive problem solver: sees shortages weeks out and resolves them before they reach the line.
• Strong analytical skills: builds and maintains planning models in Excel/Sheets and lets data drive decisions.
• Clear, direct communicator: keeps suppliers, buyers, manufacturing, and engineering aligned, and escalates early with options rather than problems.
• Thrives in change: comfortable planning around evolving designs, new suppliers, and a ramping build schedule.
• High ownership and attention to detail: treats the material plan as their own and follows every open item to closure.

Nice To Haves

• Experience supporting an NPI-to-production ramp at a hardware startup or high-growth company.
• Experience planning electromechanical components such as motors, actuators, PCBAs, batteries, and machined or injection-molded parts.
• APICS/ASCM certification (CPIM or CSCP).
• Experience with global suppliers, including Asia-based supply chains and long-lead components.
• Familiarity with PLM systems (e.g., Arena, Duro) and engineering change processes.
• Exposure to SQL, Python, or BI tools (e.g., Tableau, Looker) for planning analytics.

Responsibilities

• Own the material plan that keeps NEO production running.
• Translate the build schedule into a reliable, time-phased supply plan for commodities.
• Ensure the right parts arrive exactly when they are needed.
• Prevent production line-down events caused by material shortages.
• Maintain accurate MRP data, including BOMs, lead times, lot sizes, and on-hand balances.
• Manage inventory health within targets, including inventory turns and excess/obsolete exposure.
• Improve supplier on-time, in-full delivery through clear forecasts, accurate POs, and timely expedite/de-expedite actions.
• Execute engineering changes (ECOs) with clear phase-in/phase-out plans and minimal scrap.
• Provide a weekly clear-to-build and shortage view to manufacturing and leadership.

Benefits

• Comprehensive medical, dental, and vision coverage
• Generous paid time off, company holidays, and parental leave
