What is Flagstone? Flagstone is many things. An online savings platform, reinventing how individuals, businesses, and charities manage, protect, and grow their cash. A diverse group of people, bound by a collaborative spirit, and shared purpose. And lastly, a thriving, profitable business – where smart people do their best work. Each definition shares a common thread: our unique culture. It’s our pride and joy. And our competitive advantage. A feel for our culture: To revolutionise the savings market, we need to be at our best. But high performance takes more than talent – it takes a culture of kindness, respect, and growth. That’s why we’re building a diverse, inclusive community, where your voice is heard and valued. Where, with close support and room to develop, you can surpass even your own expectations. And be rewarded for it. We may not change the world, but we can change the world of financial technology. And all it takes is a winning mix of drive, talent, and empathy. Our culture celebrates all three. But enough about us. Let’s talk about you. Does this sound like you? You're a hands-on Engineering Lead, ideally with around 10 years' experience, ready to run a squad with real autonomy. You'll lead the Banks squad on the Bank Portal, the partner-facing application our banking partners use to view and act on their Flagstone relationship. By the time you start, the squad will have delivered the foundational rebuild (migrating banks off the legacy tool to full feature parity), and you'll pick up the next phase: building the commercial capability on top of that foundation and turning the portal into a genuine commercial engine for the partnership. NET backend, React/TypeScript frontend) working in a regulated, data-sensitive environment, so the role carries real weight: partner-facing delivery, strict data isolation between banks, and the judgement calls that come with both. What you’ll do: You'll own the squad's technical direction and quarterly roadmap, not just participate in it, driving the commercial features that build on the migrated foundation (self-serve rate changes, new product submissions, liquidity data) while keeping the newly-migrated platform stable and any remaining cohorts or legacy decommissioning on track. You'll make most technical debt and risk calls autonomously, escalating only where tribe-level coordination is genuinely needed. On people, you'll run day-to-day delivery and performance management, including the harder conversations, handling underperformance and any exits directly rather than deferring them upward. Within the FTC's 12 months, expect the emphasis to sit more on driving commercial delivery at pace than on longer-term development pathways, though coaching engineers and creating stretch opportunities is still part of the job. You'll also work as a peer across the tribe: contributing to engineering-wide standards, comparing notes with other Team Leads, and representing the squad's constraints and progress in tribe-level planning. NET is our core backend language, on Azure, cloud-first. NET (Aspire, Duende BFF, YARP) with a React/TypeScript frontend, so while backend depth is the priority, comfort reviewing across a full-stack architecture matters more here than on a purely backend squad.
