We grade, authenticate, vault, and sell millions of record-setting collectibles, all while modernizing and digitalizing the process to further our mission of helping collectors pursue their passions. We’re always on the lookout for talented people to join our growing team.  Our services span collectible trading cards, autographs, comic books, coins, video games, event tickets, and memorabilia.

Our subsidiaries include PSA, PCGS, Beckett, SGC, and Card Ladder.  Since our founding in 1986, we have graded and authenticated millions of items. We employ more than 3000 people across our headquarters in Santa Ana, California and offices in New Jersey, Texas, Florida, Japan, Shanghai, Hong Kong, Canada, Mexico, Germany, and France.  As part of our interview process, we request that candidates have their cameras on during video interviews.

This helps foster meaningful conversation and allows us to create an experience that closely resembles our standard working environment. Certain interview steps may take place by phone. For remote roles, and at our discretion, candidates may be asked to participate in an on-site interview as part of the final stages of the process.  We understand there may be occasional circumstances requiring accommodation and are happy to discuss them as needed.

Your recruiter will be able to clarify expectations and answer any questions you have.  The Power Packs engineering team is responsible for building and operating the customer-facing Power Packs experience, the backend services and internal tools that power pack configuration and purchases, and the integrations with adjacent collection systems that support the full pack lifecycle.
