About Arena Club

Arena Club is building the number one digital marketplace for collectibles. We started by reinventing the hobby with the first-ever digital card show, and we are expanding into new categories so collectors can buy, sell, grade, and showcase everything they care about in one place. Spearheaded by 5x World Series Champion Derek Jeter and serial entrepreneur Brian Lee, our fully digital marketplace is grounded in trust, transparency, and fun, featuring grading and authentication, vaulting, and digital pack openings that let collectors build and display their collections in a personalized online showroom from anywhere in the world.

About the Role

We're looking for an organized, detail-oriented Vendor Operations Coordinator to be the main point of contact between our LA-based Buying team, our vendors, and our Receiving team. You'll own the vendor portal, resolve discrepancies on incoming purchase orders, and keep product moving smoothly from vendor to warehouse to sale. When things are running smoothly, you'll support inventory by preparing cards for digital repacks and auctions.

This role is ideal for someone who enjoys problem-solving, communicates clearly across teams, and knows (or wants to learn) the trading card and graded-card space.

What You Will Do

Vendor Portal & Damages

• Manage the vendor portal, including logging and tracking all damaged items identified on incoming POs
• Coordinate return shipments and chargebacks of damaged cards to vendors, message vendors about damages, and send tracking information to them
• Determine the appropriate resolution for damaged low- and mid-value cards (return, credit, or retain) in line with company guidelines

Vendor, Buying & Receiving Communication

• Act as the primary liaison between the Buying Team, External Vendors, and the Receiving Team
• Resolve issues with PO sheets, such as missing/incorrect cards or incorrect cert numbers
• Ensure sheets are added to the operations order list on time
• Identify when vendors ship incorrectly or don't follow our shipping SOP, and escalate to the Buying team or the right contact
• Communicate PO priorities from the Buying team to Receiving so the highest-priority orders are processed first to ensure the necessary cards are being processed first
• Coordinate vendor drop-offs as the on-site point of contact

Inventory Support (Secondary)

• Prepare cards for digital repacks
• Research and verify card pricing
• Prepare cards for auction listings
• Assist with card resubmissions for grading as needed

Qualifications

• 1–2+ years of experience in operations, receiving, logistics, vendor management, or a similar role
• Strong written and verbal communication skills, with the ability to coordinate across remote and on-site teams
• Exceptional attention to detail, especially with cert numbers, SKUs, and PO sheets
• Comfortable working with spreadsheets, web portals, and online forms
• Able to prioritize competing requests and follow through independently

Preferred Qualifications

• Familiarity with trading cards, grading companies (PSA, BGS, SGC, etc.), and card pricing tools (CardLadder, eBay, etc.)
• Experience with auction or e-commerce inventory prep
