Financial Controller

Flagstone is an online savings platform, reinventing how individuals, businesses, and charities manage, protect, and grow their cash. We are a diverse group of people, bound by a collaborative spirit and shared purpose, and we are a thriving, profitable business where smart people do their best work.

To revolutionise the savings market, we need to be at our best. High performance takes more than talent; it takes a culture of kindness, respect, and growth. We’re building a diverse, inclusive community where your voice is heard and valued, with close support and room to develop.

Does this sound like you?

• You’re a qualified accountant who enjoys being close to the numbers and the business.
• You’ve run month-end, the balance sheet, and financial controls end to end, and you know what good controls look like in both complex and fast-growing environments.
• You stay calm under pressure, explain finance simply to people outside it, and you’re always looking for smarter, more automated ways of working.

What you'll do:

• Run Flagstone’s day-to-day core finance operations, ensuring our numbers are accurate, controlled, and on time.
• Own the month-end close, the balance sheet, and day-to-day financial control.
• Deliver accurate, timely management accounts.
• Keep a clean, fully supported balance sheet, with reconciliations, accruals, prepayments, and journals in order.
• Ensure direct-to-consumer and business revenue is recorded accurately.
• Manage daily cash and liquidity monitoring.
• Own financial controls that fit our scale and regulatory environment.
• Prepare for the annual statutory audit and deliver VAT returns, tax compliance, Companies House filings, and HMRC reporting.
• Ensure monthly payroll and benefits are processed accurately.
• Work closely with teams across the business.
• Deputise for the Finance Director and support the team during peak periods.
• Use automation and AI to shorten the close and reduce manual work.

What you'll bring:

• ACA or ACCA qualified, with solid post-qualified experience.
• Strong technical accounting knowledge and the pace to deliver to tight deadlines.
• Experience in a complex environment with good controls discipline.
• Experience with a modern cloud ERP system.
• A sharp eye for detail and good commercial awareness.
• Strong organisation skills and the ability to manage competing priorities.
• Clear, direct communication that builds trusted relationships.
• An empathetic, approachable style.
• Resilience through month-end, audit, and shifting priorities.
• Ownership of outcomes and sound judgement.
• Direct-to-consumer experience is helpful but not essential.

How we reward you:

• Hybrid working - Spend at least 1 day a week with your team in our collaborative London office.
• Competitive bonus scheme designed to reward high performance.
• Flexible benefits budget for meaningful benefits.
• A range of salary sacrifice options for tax-efficient savings.
