Job description

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 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.

Does this sound like you?

You're an experience Data Leader who has taken a data function through genuine transformation. You've built self-serve adoption from the ground up, shifted accountability for data insights back to product teams, and driven real adoption across a business. You understand that moving analytics from a service function to a strategic one requires changing not just tools, but how the organisation thinks about data.

What you'll do

As Lead Data Analyst, you will play a key role in shifting the function from a service that reports what has happened to one that drives decisions about what should happen next. You will work closely with the Head of Data to lay the foundations for a more strategic, consultative model, building the team, the tools, and the ways of working that will continue to move Flagstone from reactive reporting to predictive, commercially driven insights.

This will include:

• You’ll drive measurable adoption of self-serve analytics across Growth, Engagement, Partnerships and beyond. This isn't about publishing dashboards; it's about training, supporting, and tracking uptake so ad hoc request volume falls and teams own their own insights.

• Currently, too much delivery accountability sits with analytics. You'll work with tribe leads to rebalance this through sustained, active escalation. You've done this pattern before and know how to hold the line.

• Managing a full resourced, high performing team of analysts. You'll build genuine partnership with tribe and function leads, not just visibility within data leadership. You drive adoption, you don't just ship and hope.

• Leading from the front on modern tooling and applied data science methods, and building the team's capability through coaching, pairing, and structured development.

• Helping analysts understand how their role is evolving, encouraging the team to move from responding to requests to proactively identifying opportunities and influencing decisions.

• Partnering with senior stakeholders to shape problem statements, success measures, and analytical priorities.

• Owning the most complex and high-impact analytical work, including methodology selection, assumptions, and interpretation.

• Ensuring all outputs are trusted, contextualised, reproducible, and aligned with governance expectations before informing decisions.

What you'll bring

• Significant experience in data analytics, including ownership of high stakes analysis and operation as a hybrid IC / manager.

• Proven track record of landing self-serve adoption where you've led a team through this shift before. You can point to measurable outcomes e.g. falling ad hoc volume, teams confidently self-serving, sustained change.

• Experience rebalancing accountability in matrixed environments. You've worked in cross-functional organisations where product/tribe leadership needed to own their data insights. You know how to elevate, how to hold boundaries, and how to make the shift stick.

• Demonstrated ability to build partnerships across functions, not just within your team or your immediate leadership chain, but with tribe leads, product managers, and operational teams. You've driven adoption of your team's work.

• Strong hands‑on technical capability - deep SQL, Power BI, Python or similar. You build capability by doing, not just directing.

• Communication and conviction, with the ability to operate credibly with senior stakeholders and hold the line on quality and ways of working when it matters.

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:

• Hybrid working - Spend at least 1 day a week with your team in our collaborative London office

• Competitive bonus scheme - designed to reward and recognise high performance

• Flexible benefits budget - a pot to fund meaningful benefits for you, whether it's hormone or fertility testing, cancer screening, neuro‑diversity coaching or something that matters for you.

• A range of salary sacrifice options to help you make tax efficient savings on electric cars, nurseries schemes, home and tech goods.

• Working Abroad - Flagstone employees can work remotely from an approved list of locations for up to 90 days a year

• Mental wellbeing support – Access therapy and mental health sessions through Spill

• Learning and development – £1,000 personal development budget to help you grow in your role.

• Private health care - Enjoy all the benefits AXA has to offer, including reduced gym memberships and medical history disregarded

• Medical cash plan - To help you with the costs of dental and optical expenses

• Life insurance and Income Protection- four times your annual salary for peace of mind

• Matched pension contributions up to 5%

• 25 days holiday - plus bank holidays, well‑being days and volunteering days

• Enhanced Parental Leave – enhanced maternity, paternity and adoption pay.

All are welcome.

At Flagstone, we’re assembling a diverse team that defies our industry’s norms. Think this role could suit you?
