Job description

Overview

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.

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.

About The Role

We are looking for a Senior Software Engineer, Back-End to help build and scale the systems that power the Collectors Vault — our secure storage platform that enables collectors to manage, protect, buy, sell, and move their assets with confidence. The Vault sits at the center of the Collectors ecosystem, connecting grading, marketplace, fulfillment, and ownership experiences across trading cards, coins, video games, and other collectibles. As collectors increasingly transact digitally, the Vault serves as the trusted foundation that powers asset ownership, inventory management, transfers, and commerce at scale.

You'll design, build, and operate the backend services that support millions of collectible assets and their lifecycle within the Vault. Working closely with product managers, designers, and fellow engineers, you'll develop reliable, scalable systems that enable seamless customer experiences while ensuring the accuracy, security, and integrity of customer assets. This is a high-impact role on a team responsible for some of Collectors' most strategic platform capabilities, helping shape the future of digital collecting and ownership.

We believe there is significant value in onsite partnership and team collaboration, and candidates within 1-hour commuting distance of the office may be expected to work onsite most of the time. Additional details will be discussed during the recruiting process.

What You'll Do

• Design and build scalable cloud-based systems on AWS that power core collectibles platforms and experiences
• Develop APIs and backend services
• Own technical architecture and delivery of end-to-end features, from design through deployment, with senior-level influence across teams
• Improve and evolve existing systems, identifying opportunities to enhance performance, scalability, and reliability
• Leverage modern AI tools and techniques to accelerate development, improve engineering velocity, and explore new ways of building
• Provide technical leadership through design reviews, code reviews, and mentorship, raising engineering quality across teams

Who You Are

• 5+ years of software engineering experience building web applications, APIs, and distributed systems at scale
• 2+ years of hands-on AWS experience, including serverless and event-driven architectures
• Java strongly preferred, and not afraid to take on other new technologies. Proficiency or familiarity with C# is a plus
• Use modern AI tools (e.g. Claude Code CLI, Codex) as a crucial part of your development workflow to accelerate delivery, improve engineering velocity, and explore new approaches to building that drive team-wide productivity and innovation
• Strong fundamentals in engineering (OOP, design patterns, testing, security, observability)
• Proven experience working in fast-paced, cross-functional product teams embedded with Product, Design, TPM, and Business partners, shaping requirements, tradeoffs, and execution end-to-end
