As a Principal Software Engineer, you'll be the most senior individual contributor in our Technology function. Reporting to the Head of Engineering and working closely with the CTO, you'll own our engineering standards, technical direction, and above all - our shift from AI-assisted coding to AI-led delivery, where engineers direct and verify rather than type. This is a hands-on technical leadership role with no requirement to manage people, unless you want to.
You'll guide several squads, earning influence through judgement and delivered outcomes, while taking direct ownership of whichever initiatives carry the most technical risk or upside at any given time. Our current focus is opening Defaqto data to developers and AI agents through well-governed APIs and MCP servers - but the role is defined by the level you operate at, not by any one product, so expect what you own to change as our priorities do.
You'll also be a genuine sounding board for technology leadership, equally comfortable shaping multi-year strategy or unblocking a production issue this afternoon. If you're the engineer others go to when a decision really matters, and you want the remit to raise the bar across the whole organisation, this is that role.
