Sotheby's - Senior Software Engineer

• You've shipped production systems. 5+ years of experience, with real ownership of services or products that other people depend on. You've dealt with incidents, made trade-offs under pressure, and learned from what went wrong. • You've shipped production systems. • You solve problems for the business, not just yourself. You're pragmatic. You look for the best course of action given the constraints, not the most technically interesting one. You can weigh options, make a call, and move forward together with the people around you. • You solve problems for the business, not just yourself. • You communicate clearly. Whether that's justifying a technical decision on a call, writing up a proposal, or talking through an approach in a review. You can discuss specifics without getting lost in the detail, and you're comfortable working across teams to get things done. • You communicate clearly. • You're comfortable wearing many hats. The day to day here can vary a lot. You're the kind of engineer who sees that as a feature, not a bug. • You're comfortable wearing many hats. • You take craft seriously and use modern tools to amplify it. You write code that others can maintain and build on. You're happy using AI and modern tooling to move faster, but you understand the systems deeply enough to know when the tool is wrong. • You take craft seriously and use modern tools to amplify it. • We don't expect you to know the full stack coming in.

It's how we're built, and it's how we intend to stay. • 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. • This role is London or remote within the UK.
