The engineering that powers it today reflects that same ambition, built on modern technologies and modern practices.</p> <p>Auctions are the most visible part of what we do, but every sale that runs through Sotheby's is backed by the entire engineering organisation. The work starts months before a lot crosses the block, from the systems that support how we acquire and value inventory, through to the platforms our clients and specialists interact with daily, the identity and compliance infrastructure that keeps it all trustworthy, and the services that make the live event itself possible.</p> <p>That breadth is what makes the engineering here different. Whether you're working on internal tooling, client-facing products, platform infrastructure, or the real-time systems behind a sale moving hundreds of millions of dollars, your work connects to something tangible.</p> <p>We're looking for senior engineers who want real ownership of the systems they build, who care about quality and craft, and who are curious enough to learn a domain that will surprise them.</p> <p><em>Our engineering teams are remote-first and globally distributed. It's how we're built, and it's how we intend to stay.</em></p> <p><em>We're not async-only. There are regular calls, cross-team meetings, and plenty of direct collaboration alongside the written communication you'd expect from a distributed organisation. The balance works because the people here are good at both.</em></p> <p><em>This role is London or remote within the UK.</em></p> <p><strong>IDEAL EXPERIENCE & COMPETENCIES</strong></p> <ul> <li><strong>You've shipped production systems. </strong>5+ years of experience, with
