We are hiring a Materials Coordinator to support our supply chain operations across receiving and purchasing. This is a hands-on role where your work directly impacts our builds. We will train you on our systems and processes. You do not need to arrive knowing BESS. You do need to arrive organized, dependable, and ready to move fast.

Requirements

• Experience in purchasing, receiving, inventory, or materials coordination, preferably in a hardware, manufacturing, or industrial environment
• Hands-on receiving experience: you have physically received shipments, verified them against a PO, and documented what you found
• Knows how to catch a problem at the door: you can identify a short shipment, a wrong part, or shipping damage and you know what to do next
• Comfortable working in spreadsheets and able to keep data clean, accurate, and organized
• Strong attention to detail with part numbers, quantities, serial numbers, dates, and dollar amounts
• Clear written communication for internal documentation, discrepancy reports, and escalations
• Willing to work hands-on in a shop floor environment, including receiving and handling heavy or oversized electrical equipment

Nice To Haves

• Experience with energy storage, batteries, electrical components, or industrial equipment
• Familiarity with procurement or spend management software
• Experience writing or processing Non-Conformance Reports (NCRs) or similar discrepancy documentation
• Experience at a startup or early-stage hardware company where processes are still being built
• Basic understanding of shipping documentation, import paperwork, or freight coordination
• Exposure to basic invoice reconciliation or accounts payable processes

Responsibilities

• Receive incoming shipments on the shop floor and perform a systematic check on every delivery: verify quantities against the purchase order, confirm part numbers and model numbers match, check for shipping damage on all packaging and equipment, and verify serial numbers and lot numbers where required
• For high-value or complex items such as battery systems, transformers, inverters, and electrical assemblies, follow the inspection checklist and document the condition of each item with photos before moving it to storage
• Identify and immediately escalate any discrepancy: short shipments, wrong parts, damaged goods, missing documentation, or serial number mismatches
• Log all receipts accurately in our receiving system, including quantities received, condition notes, serial numbers, and lot numbers, and submit for manager approval before invoices are cleared
• Complete and submit a Non-Conformance Report (NCR) for any damaged, missing, or non-conforming material, including photos and a clear written description of the issue
• Keep parts location and on-hand quantity data accurate and current so the team always knows what is on site
• Support purchase order creation, tracking, and expediting across active projects, using correct cost codes and project codes for each build
• Place orders with approved vendors and confirm pricing, lead times, and ship dates
• Expedite open orders and flag late or at-risk parts before they affect the build schedule
• Track open POs across multiple active projects and keep status current
• Collect quotes and vendor documents as directed and organize them for review
• Perform a three-way match on every invoice: verify quantity, part number, and price against the purchase order and the receipt
• Flag any invoice discrepancies to the appropriate team with supporting documentation

Benefits

• We are a small, fast-moving team that genuinely loves what we build. Everyone wears many hats, takes real pride in the work, and has each other's back. No politics, no silos.
• We are also driven by something bigger. Clean, reliable energy storage is one of the most important problems of our time, and what we build makes a real difference. If that kind of mission matters to you, you will fit in well here.
• From day one, you will have real ownership. Your work keeps active energy storage builds moving, and the people around you will know it. This is not a back-office job, it is a hands-on role where what you do is visible and it matters.
• Grow inside a company that is growing. There is real room to develop, take on more, and shape how things are done.
• Critical Loop is an equal opportunity employer. We're committed to building a diverse team and creating an inclusive workplace where everyone can thrive.
