Collectors is the leading creator of innovative technology that provides value-added services for collectors worldwide. 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. We’re transforming the collecting experience with technology that brings authentication, grading, and trading into the modern era. Our products are equalizing the playing field by providing tools that make complex research analytics — including pricing, scarcity reports, and historic sales data — accessible to every collector, old or new. Grading is an opinion service — but behind that opinion sits decades of expertise and an increasingly powerful data and technology engine. We authenticate and grade collectibles across cards, coins, banknotes, video games, tickets, and more through our iconic brands — PSA, Beckett, SGC, PCGS and more — which serve as the industry’s trusted standard of quality and integrity. As the collectibles market evolves into a mature, data-driven asset class, we are investing heavily in the quantitative infrastructure that underpins our business — from market pricing and grading intelligence to lending and financial products built on top of our dataset. We’re looking for a Lead Quantitative Scientist to build and lead the quantitative modeling capability at the core of Collectors’ next phase of growth. You’ll own two critical domains: Lending & Underwriting — designing and scaling the ML and quantitative models that power automated underwriting for our lending business, where collectibles authenticated and graded by our brands serve as collateral — and Financial Forecasting — building predictive models that forecast collectible valuations, market dynamics, and pricing trends, strengthening the intelligence layer beneath PSA, Beckett, PCGS, and our broader ecosystem. You’ll operate as the founding, senior individual contributor going deep on modeling and infrastructure, with an opportunity to grow a high-caliber team over time. You will report into VP of Corporate Development and Strategy and work out of the office from our Santa Ana, CA or Jersey City, NJ location. Remote or hybrid candidates will also be considered, this will be discussed further during the recruiting process. We believe that there is significant value in in‑person collaboration. If you live within a 1‑hour commuting distance to one of our offices, you will be required to be onsite most of the time. This will be discussed further as part of the recruiting process.
