At NovaSensor, an Amphenol company, we are pioneers in high accuracy sensing solutions. As a global leader in MEMS (Microelectromechanical Systems) technology, we design and manufacture advanced pressure sensors that power critical applications across the medical, industrial, and transportation markets—whether it is enabling life-saving medical devices, enhancing vehicle safety and efficiency, or ensuring reliability in industrial systems.

We are part of Amphenol, a global leader in advanced interconnect systems, serving diverse markets including automotive, aerospace, industrial, and mobile devices. Amphenol Corporation, a member of the Fortune 500 (NYSE: APH), was established in 1932 and has pioneered innovation in electronics for nearly a century across virtually every end market.

The Planner/Buyer is responsible for ensuring the right parts are available, at the right time and quantity, to meet production plans while minimizing inventory and cost. This role manages day-to-day Planned Order Actions, purchase order follow-up, inventory control, supplier communication, and cross-functional collaboration with Production, Engineering, Quality, and Logistics to support stable manufacturing operations and new product introductions.

• Support New Product Introduction (NPI) by planning material releases, identifying and securing critical long-lead items to meet Product release timelines.
• Perform regular cycle counts and support physical inventory; investigate and correct inventory discrepancies.
• Liaise with Quality and Engineering on nonconforming materials, part changes, and BOM updates; ensure BOM accuracy within ERP.
• Monitor supplier performance (on-time delivery, lead time variance) and elevate supply risks proactively.
• Prepare and maintain planning documentation, reports, and metrics for management (inventory turns, days of inventory, OTIF, forecast accuracy).
• Drive continuous improvement in planning processes, including automation, BOM clean-up, and lead-time reduction initiatives.
• Ensure compliance with company purchasing policies, import/export requirements, and record-keeping.
• Implement data-driven inventory management strategies to mitigate material risks, such as Excess and &Obsolete (E&O) and Purchase Price Variances (PPV).
