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.

Off-Site Storage & Capacity Buildout
- 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
Quality, Compliance & Documentation
- Ensure material control compliance with 21 CFR Part 820/QMSR and ISO 13485
