Information Security Team Lead

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 an experienced security leader who enjoys building capable and effective teams while embedding security into everyday technology and business processes. You’re comfortable balancing hands on input with coaching, strategy, and operational management.

You can clearly explain the “why” behind security controls, work collaboratively across Technology, Risk, Compliance, and Product, and take a proactive approach to managing risk, incidents, and continuous improvement.

• Experience with security risk management, governance, and incident response
• Knowledge of cloud security principles (Azure preferred) and modern security tooling (SIEM, EDR, vulnerability management, etc.)
• Ability to communicate security concepts clearly to technical and non technical audiences
• A proactive, improvement focused mindset with excellent stakeholder collaboration skills
• Experience in supporting the secure adoption of AI technologies, including AI governance, risk management, and control frameworks (or an interest in developing this area)
