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 marketing led growth leader who gets that the best acquisition strategies don't sit in a marketing plan alone, they get built at the intersection of marketing, product, and finance.

You're as comfortable briefing a campaign, testing a new landing page, or reworking how the website converts. You bring structure to ambiguity, using data and insight to work out what to prioritise and you're ready to take an ISA proposition from its infancy to becoming a significant driver of AUA.

What you'll do

Growth at Flagstone isn't a single campaign or a single channel, it's a squad-level discipline, and this role owns it for our highest-value customer segment. As Lead of the HNW Acquisition Squad, you'll report to your Tribe Lead and take ownership of three connected areas: our HNW proposition, our ISA growth ambitions, and the website that serves every audience.

What you'll bring

Backgrounds we're interested in

We're deliberately open on background for this one. Whether you've come up through growth marketing, product, or a broader commercial or acquisition path, what matters is that you've owned outcomes, led teams through ambiguity, and know how to turn data into decisions.

We'd love to hear from people who've worked in marketing-focused, fast-paced businesses with a broad remit, ideally somewhere close to regulated financial services. If your profile doesn't tick every box but the role sounds like the right challenge, please apply anyway.

How we reward you

At Flagstone, the benefits extend beyond false gifts like "fruit and snacks". Instead, we invest in your health, wealth, and professional development. Here's a selection of our benefits:

All are welcome.

At Flagstone, we're assembling a diverse team that defies our industry's norms. Think this role could suit you? We encourage you to apply, no matter your background.
