Position Overview

South 8 is hiring its first Supply Chain Planning Lead to own and execute the material plan that keeps battery cell production running across multiple integrated sites. This person will translate production schedules into supplier forecasts and purchase orders, and make sure the right components are at the right site in the right quantities on time. This is a hands-on role at a company where the planning processes are still being built; the role will be responsible for running today's models and making them better as volume grows. The ideal candidate will have experience in material planning at early stage manufacturing operations, and will be comfortable working with supply chain, manufacturing, engineering, and finance teams in cross-functional settings.

Key Responsibilities

Production and material planning

• Build and maintain material requirements plans for South 8 and contract manufacturers based on aligned production schedules, bills of materials, lead times, and forecasted inventories at each site. Improve these models over time.
• Update and publish production and material/component procurement forecast models on a set cadence and whenever schedules, yields or build requirements change.
• Manage inventory tracking and reconciliation at contract manufacturers and internal sites; report on inventory levels, shortages, and material spend.
• Identify and clearly communicate inventory, procurement, or other risks that could disrupt production plans.
• Work with program management and company leadership to maintain long term planning models and company roadmap.
• Support the development and implementation of new processes and tools, including ERP or MRP systems, as South 8 scales production volumes.

Purchasing and supplier management

• Create and release to suppliers binding material and component procurement forecasts that deliver South 8's operational needs and minimize costs.
• Place and manage purchase orders for cell components, electrolyte raw materials, and production consumables.
• Set and maintain safety stock and reorder points for critical and long-lead materials.
• Track supplier on-time delivery and quality issues, taking action to adjust planning as necessary and mitigate supply issues that would impact production plans
• Support international part and material logistics, including document preparation, transport, and customs clearance.

Qualifications

Required

• Bachelor's degree in supply chain, operations, engineering, business, or a related field, or equivalent experience.
• 3+ years in material planning, production planning or purchasing in a manufacturing environment.
• Hands-on experience building forecasts and material requirements plans from production schedules and BOMs.
• Advanced Excel or Google Sheets skills; you can build a model others can use.
• Excellent communication skills, both verbal and written. You can identify and explain problems, changes, and tradeoffs.
• Comfort with ambiguity and changing priorities in a small, fast-moving team.

Preferred

• Experience at a startup or in early-stage manufacturing.
• Experience managing consigned inventory or working with contract manufacturers, especially overseas.
• Experience working with ERP/MRP systems (example Sage, Netsuite, SAP); experience implementing one a plus.
• Willingness to deliver epic high fives
