Inventory Manager

SiPhox Health seeks an experienced Inventory Manager to build and own materials management for our Burlington manufacturing and lab operations. You'll own materials flow end-to-end for a regulated diagnostics manufacturer — purchase requisition, receiving/inspection, storage, production consumption, outbound shipment, and off-site capacity. This means standing up the inventory system of record and part numbering/BOM/transaction structure; setting inventory policy; owning material control processes auditors will review;

and managing supplier delivery performance, freight, and dangerous goods compliance.

This is a build-from-the-ground-up IC role with real autonomy and no existing playbook. You'll set direction and do the work, influencing R&D, Manufacturing, Quality, Regulatory, and Finance without formal authority. Ideal candidates have run materials management in a regulated manufacturing environment, stood up or rebuilt an inventory system, and are credible on the receiving dock, in a spreadsheet, and in front of an auditor.

• Select, implement, and own the ERP/inventory system — item master data, part numbering, UOM, location/bin structures, BOM accuracy
• Define transaction model (receipts, issues, moves, adjustments, returns) and controls keeping system quantities accurate
• Own lot/batch/serial traceability supporting device history records and post-market traceability
• Design and run cycle count and physical inventory programs; drive discrepancies to root cause
• Own inventory reporting (accuracy, turns, aging, obsolescence, burn rate, fill rate)
• Migrate records from spreadsheets/ad-hoc tools into the system of record

• Set reorder points, min/max levels, safety stock, ABC classification, lead-time data
• Own material availability against production schedules; identify long-lead/single-source/allocation risk and drive mitigation
• Balance line-down risk against working capital and expiry exposure
• Drive disposition of slow-moving, excess, and obsolete inventory
• Forecast material/storage needs against ramp plans

• Own receiving and incoming inspection under the eQMS, including receipt transactions triggering payment
• Own material status control (accepted/quarantined/on-hold/rejected); initiate and close NCRs with Quality
• Own stock room, loading dock, and controlled storage areas — layout, labeling, capacity, environmental monitoring, access control
• Own supplier documentation intake (CoA/CoC, calibration certs, material certs) for audit readiness
• Own cold chain receipt handling and excursion escalation
• Partner with Facilities on stock room/dock upkeep and EHS on chemical inventory, SDS library, gas cylinders, hazardous waste
• Negotiate pricing/terms/lead times; track savings against total landed cost
• Manage supplier delivery/quality performance; elevate or requalify as needed
• Own supplier onboarding and Approved Supplier List
• Own three-way match resolution (PO/receipt/invoice) with AP

• Own outbound logistics for regulated/unregulated goods (finished product, samples, capital equipment, returns)
• Hold dangerous goods shipper certification; own DOT/IATA/ICAO/IMDG shipments (dry ice, UN3373 biological substances, hazardous chemicals)
• Own shipping documentation: packing lists, bills of lading, commercial invoices, DG declarations, HTS classification
• Own export compliance and customs broker/freight forwarder relationships
• Own direct fulfillment for small parcel orders (pick, pack, lot capture, returns)
• Evaluate 3PL/fulfillment partners as volume grows

• Identify, evaluate, and build out off-site storage: site selection, cost/lease comparison, layout/racking design
• Establish controls for off-site locations (access, segregation, monitoring, transfer procedures)
• Manage ongoing off-site operations including transfers, counts, moves

• Ensure material control compliance with 21 CFR Part 820/QMSR and ISO 13485
• Author and revise SOPs, work instructions, and forms; deliver training
• Serve as process owner for material control in audits; carry findings through CAPA to closure
• Own calibration/monitoring of inventory-related equipment (scales, temp/humidity monitors, data loggers)

• Design and roll out process for inventory/supply requests
• Treat internal colleagues as customers; respond promptly, close the loop on changes
• Partner with R&D, Manufacturing, Quality, Regulatory, Finance on material availability
• Escalate cost/lead-time/quality issues early with recommendations
• Execute stocking, kitting, staging, point-of-use replenishment while the function is small
• Support facility projects, equipment installs, and moves
• Build the function to scale: workflows, tooling, automation, capacity
• Reduce manual transactions, errors, and cost through process improvement
• Apply 5S/lean principles to storage,…
