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, the UK, 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. Our engineering mission is to democratize technology while promoting innovation, collaboration, and continuous learning throughout the organization.

We're looking for a Senior Fraud Analyst to be on the front line of keeping our collector community safe. You'll review flagged orders, accounts, and claims, make clear and fair decisions, and communicate with customers when something needs a closer look. This role combines investigative work with a customer-first mindset: stopping bad actors while keeping the experience smooth for the many legitimate collectors we serve. You'll report to the Fraud Operations Lead and work closely with Customer Care, Payments, Security, and the Fraud Technology team.

Remote or hybrid candidates will also be considered. 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.

What You'll Do:

• Build and tune detections. Design, build, and maintain detection logic that identifies fraud patterns across account creation, authentication, payments, and other high-risk user flows, and tune it continuously to balance catch rate against false positives.
• Hunt for emerging threats. Lead proactive threat hunts using hypothesis-driven investigation to uncover emerging fraud schemes, abuse rings, and attacker tradecraft before they show up in losses.
• Own the fraud telemetry pipeline. Identify gaps in signal coverage, partner with product and platform teams to instrument new data sources, and aggregate device, network, behavioral, and transactional signals into usable, well-documented datasets.
• Turn findings into automation. Translate hunt findings and investigator feedback into durable, automated detections, treating detections as code with version control, testing, and deployment practices.
• Equip fraud operations. Build the tooling, dashboards, and enrichment that make fraud analysts and investigators faster and more accurate.
• Measure what matters. Track detection performance through precision, recall, coverage, and time-to-detect, and use that data to prioritize where to invest next.
• Fix problems at the root. Partner closely with fraud operations, security, data engineering, risk, and product teams to align on threat priorities and close systemic gaps rather than individual cases.
• Stay ahead of the landscape. Track external fraud trends, including new tooling, marketplaces, and techniques, and assess how they apply to our environment.

Who You Are:

• Experienced in detection work. You have 4+ years of experience in fraud detection, detection engineering, threat hunting, trust and safety, or a closely related security or data role.
• Technically hands-on. You write strong SQL and can provide deep subject matter expertise for analysis, automation, and building detections.
• Fluent in data at scale. You’ve worked with large-scale event data and understand how logging, data pipelines, and streaming or batch processing fit together, whether in a SIEM, data warehouse, or lakehouse environment.
• Adversarial by instinct. You can look at a product flow and identify how it would be abused, then figure out what signal would reveal it.
• Comfortable with ambiguity. You can take a vague “something’s off” and turn it into a testable hypothesis, a finding, and a lasting control.
• Pragmatic about methods. You understand the tradeoffs between rules-based detection and statistical or ML approaches, and know when each is the right tool.
• A clear communicator. You can explain technical findings to both technical and non-technical stakeholders, and frame why a detection matters in terms of risk and loss.
• Disciplined about engineering. You care about documentation, testing, reproducibility, and building systems other people can maintain.
