About the Role

Ironsite is seeking a Supply Chain Manager (Buyer / Planner) to oversee manufacturing and demand planning, materials management, and supply chain operations for the company's hardware. This is a foundational role for an early supply chain hire, responsible for building the supply chain function from the ground up to support scaling from thousands to hundreds of thousands of devices.

Responsibilities

• Own the manufacturing planning process end to end, from demand signal through MO release.
• Manage the material requirements planning (MRP) system, ensuring accurate lead times, safety stock, and reorder points for all key materials and components.
• Coordinate closely with product management, engineering, and supply chain to translate demand forecasts into executable production plans.
• Publish and maintain rolling production and demand plans (weekly, monthly, quarterly) that reflect capacity, material availability, and business priorities.
• Manage raw material planning, procurement, and inventory levels to support production ramp, service, and repair needs.
• Drive inventory optimization initiatives to minimize excess and obsolete inventory while ensuring supply continuity.
• Manage inventory turns, days on hand, and material flow across internal facilities, CMs, and 3PLs.
• Own ECR and ECO impact assessments on inventory and material planning. Coordinate implementation across CMs and internal teams.
• Interface with contract manufacturers to align production schedules with demand and material availability.
• Track and drive production KPIs, including on-time delivery, yield, and lead time.
• Identify and mitigate supply and production risks proactively, escalating decisively when needed.
• Support new product introduction (NPI) supply planning, including material readiness for prototype builds and ramp planning for volume production.
• Own the ERP (NetSuite or similar) configuration for supply chain operations, including item master data, supplier master data, BOM management, and work order flow.
• Build and improve reporting on production, inventory, and materials KPIs so leadership always has real-time visibility into supply chain health.
• Establish and document the supply chain operating cadence (S&OP, MRP reviews, weekly supply meetings) that will scale with the company.

Requirements

• 5-8+ years of experience in supply chain, manufacturing planning, or operations management at a hardware company that scaled from early production to volume.
• Deep experience with MRP, MPS, and S&OP processes in a manufacturing environment.
• Strong ERP experience (NetSuite, Oracle, SAP, or similar) and demonstrated ability to configure and improve supply chain workflows within those systems.
• Hands-on experience managing contract manufacturers and coordinating production plans with overseas partners.
• Strong analytical skills. Comfortable modeling demand, capacity, and inventory scenarios in spreadsheets or with SQL.
• Detail-oriented, self-motivated, and able to respond quickly to a fast-moving and ever-changing environment.
• Ability to generate clear and concise updates to all levels of internal and external stakeholders, including at the executive level.
• Experience with wearables, consumer electronics, or ruggedized hardware programs.
• Prior experience as an early supply chain hire at a hardware startup that scaled from early volumes to full production.
• Familiarity with contract manufacturing partners in Taiwan, mainland China, or Southeast Asia.
• Experience with battery pack and optical subassemblies.
• Comfort with international travel to CMs and suppliers as needed.
• Proficiency with PLM systems (Arena, Propel, or similar).
• Mandarin or Vietnamese language proficiency.
• Experience with 3PL management and logistics network design.
• Familiarity with lean and continuous improvement methodologies.
