About Sphere
Sphere Corporation is a KOSDAQ-listed global aerospace and advanced materials company supplying aerospace-grade specialty alloy products to leading U.S. aerospace and space customers.
As our Aerospace business grows rapidly, we are strengthening our Korea-based supplier-facing team to improve delivery visibility, vendor responsiveness, and execution across key product lines, including tubing, bar, plate, and sheet.
Role Overview
The Procurement / Buyer, Aerospace will be responsible for managing supplier schedules, tracking work-in-progress (WIP), identifying delivery risks, and supporting timely execution with Korea-based vendors.
This is a supplier-facing role that requires close communication with vendors, frequent on-site presence, and strong coordination with Sphere’s U.S. customer-facing teams. You will help ensure that supplier progress is visible, delivery risks are escalated early, and open action items are followed through to closure.
Product or vendor coverage may include tubing, bar, plate, sheet, or other aerospace product lines depending on business needs.
Why This Role Matters
As the Aerospace business scales, Sphere needs stronger day-to-day visibility into vendor progress and delivery execution. The U.S. Account Managers are responsible for customer-facing communication, but due to time zone differences and the level of vendor follow-up required in Korea, dedicated Korea-based Procurement / Buyer support is essential.
This role will help improve WIP tracking, supplier schedule management, delivery responsiveness, and internal communication between Korea-based vendors and the U.S. team.

- Support timely reporting of supplier progress to the U.S. team
3. Supply Gap Resolution
- Identify supply gaps and open issues that may impact customer delivery
- Work with vendors and internal teams to close open action items
- Track issue status until resolution
- Communicate risks clearly and request support when escalation is needed
4. Vendor Communication & On-Site Coordination
- Communicate directly with assigned vendors to secure accurate schedule and delivery information
- Maintain a professional working relationship with vendors while ensuring required follow-up is completed
- Spend time on-site at vendor locations as needed to verify progress and support execution
- Help improve vendor responsiveness and delivery discipline
5. Cross-Functional Collaboration
- Coordinate closely with U.S. Account Managers and internal Korea-based teams
- Provide timely updates on supplier progress, risks, and action items
