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.

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.
