The Role:

We are looking for a Buyer Planner to join our Supply Chain team. As a Buyer Planner, you'll be part of a cross-functional team whose mission is to lead IonQ on its journey to build the world's best quantum computers to solve the world's most complex problems.

In this role, you will own the buy side of the material plan - converting demand into purchase orders, holding vendors to committed dates, and keeping the supply picture in the ERP accurate enough that the rest of the organization can plan against it. You are the connection point between what the factory needs and what the supply base has actually agreed to deliver.

This is a high-volume, high-judgment execution role. Lead times are long, demand shifts, and a large share of what you buy is custom or single-source. The ideal candidate is someone who works a queue with discipline, chases commitments rather than replies, and understands that a date is only real once it is recorded in the system.

Responsibilities:

Purchasing Execution

• Review the buyer workbench daily for new demand, pull-ins, quantity changes, and cancellations before releasing anything, so that every release is a deliberate decision
• Release compressed lead time purchase requests first, prioritizing items past the Suggested Order Date, then batch standard within-lead-time releases
• Create Transfer Orders to connect supply and demand across locations and subsidiaries, checking other locations' on-hand before releasing a new PO
• Work the purchase request intake queue end to end: requests assigned to you, items needing a vendor or vendor part number, quote requests, returned or rejected requests, and approved requests with no PO created yet
• Return a status note to the requester on anything aging in the queue

Delivery & Supplier Management

• Chase purchase order acknowledgments where a vendor has not confirmed price, quantity, and date
• Confirm delivery dates and update the PO with each new committed date
• Drive expedite and pull-in requests for material creating a shortage or a compressed date;

Data Integrity & Financial Accuracy

• Resolve three-way match discrepancies - price variance, quantity variance, or missing receipts - correcting whichever record is actually wrong rather than forcing the invoice through
• Establish and maintain lead times in NetSuite for items missing them
• Identify and load preferred vendors and vendor part numbers for items missing them

Requirements:

• [2]+ years of purchasing, buying, or materials planning experience in a manufacturing environment, or an equivalent combination of education and experience
• Bachelor's degree in Supply Chain, Operations, Business, or a related field, or equivalent practical experience
• Working knowledge of MRP/ERP purchasing mechanics - planned orders, suggested order dates, lead time logic, exception messages
• Direct experience managing vendor relationships and holding suppliers to committed delivery dates
• Strong Excel skills - pivot tables, lookups, and the ability to build a working analysis without waiting on a report request
• Ability to read and interpret BOMs and engineering drawings well enough to buy the right part
• Organized and persistent; able to work a large daily queue to completion and communicate status clearly

Preferred Qualifications:

• Experience with NetSuite or a comparable Tier 1/Tier 2 ERP
• Experience with an intake or procure-to-pay tool such as Zip, Coupa, or Ariba
• Background in high-mix / low-volume, prototype-to-production, or new product introduction environments
• APICS/ASCM certification (CPIM, CPSM, CSCP) or active pursuit
• Experience buying custom fabrication, machined parts, electronics, or long-lead capital equipment
• Familiarity with three-way match, receiving, and AP resolution workflows
• Working knowledge of business analytics reporting tools

US Technical Jobs. The position you are applying for will require access to technology that is subject to U.S. export control and government contract restrictions. Employment with IonQ is contingent on either verifying “U.S. Person” (e.g., U.S. citizen, U.S. national, U.S. permanent resident, or lawfully admitted into the U.S. as a refugee or granted asylum) status for export controls and government contracts work, obtaining any necessary license, and/or confirming the availability of a license exception under U.S. export controls. Please note that in the absence of confirming you are a U.S. Person for export control and government contracts work purposes, IonQ may choose not to apply for a license or decline to use a license exception (if available) for you to access export-controlled technology that may require authorization, and similarly, you may not qualify for government contracts work that requires U.S. Persons, and IonQ may decline to proceed with your application on those bases alone. Accordingly, we will have some additional questions regarding your immigration status that will be used for export control and compliance purposes, and the answers will be reviewed by compliance personnel to ensure compliance with federal law.

US Non-Technical Jobs. Due to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum. Accordingly, we will have some additional questions regarding your immigration status that will be used for export control and compliance purposes, and the answers will be reviewed by compliance personnel to ensure compliance with federal law.
