Group Product Manager in London

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.

Does this sound like you?

Our Partnerships Tribe is one of our fastest growth engines.

The tribe exists to expand referrals, assets and revenue through three routes: the advisors who refer clients to us, the banks we partner with to hold client cash, and the API partners who embed Flagstone's platform directly into their own products.

We currently have an exciting opportunity for a Group Product Manager to lead product strategy across all three: Introducer, Bank, and API Partnership.

This is a commercially significant role — sitting at the heart of how Flagstone grows its partner ecosystem — with material revenue impact.

What you’ll do

You’ll own product strategy across the tribe, coordinating multiple products at different stages of development and translating customer and business needs into a clear roadmap.

Day to day, that means three connected areas of focus

• Directly contribute to our mission to empower people to protect and grow their cash with ease – helping build the partner ecosystem that brings clients, advisors, and financial institutions into the Flagstone platform.
• Lead the Partnerships tribe as Group Product Manager – driving best‑in‑class product outcomes across three squads: Introducer, Bank, and API Partnership, collectively one of the most commercially significant parts of the business.

You'll operate as both strategic leader and hands‑on contributor, knowing when to zoom out and set direction and when to step in directly alongside the squad.

• Be partner and customer focused, building a deep understanding of how advisors, banks, and API partners experience our products – and using that insight to identify where to invest and what to build next.
• Define product goals and OKRs within the partnerships space, regularly measuring and communicating progress to stakeholders – bringing them on the product journey with you.
• Work closely with cross‑functional teams across UX, Tech, Operations, and Commercial to define and own the product roadmap for your tribe, prioritising features that grow referrals, assets and revenue.
• Own the advisor referral experience – understanding how advisors register, refer, and convert clients, and continuously improving the funnel that drives Flagstone's introducer channel.
• Partner closely with our sales‑led team to translate new bank partnership wins into clear product requirements, and drive ongoing engagement with the new bank portal.
• Build and scale our API partner programme – owning the product experience for partners such as Revolut, focused on onboarding new integrations and growing Au A through the API channel.
• Collaborate with development teams to deliver solutions that meet the needs of partners and their clients, translating requirements into well‑defined, prioritised work.
• Work as part of an agile team to deliver value early and often, managing the product backlog to maintain clear priorities and best‑practice product management standards across squads.
• Drive improvements to how we build better products at scale, leading by example in product operations across the wider function.
• Be the voice and champion of the partner and end user – putting the people who use our products at the heart of every design and product decision.
• Provide support to a team of Product Managers who will report into you, coaching and supporting them in both their career development and day‑to‑day activities.

What you’ll bring

• Several years’ experience as a Group Product Manager or similar related product leadership role.
• Experience managing or coaching other product managers, with a track record of helping them grow.
• Confidence using data and customer research to shape product strategy and prioritise across competing demands.
• A track record of building and communicating a multi‑month roadmap to a range of stakeholders.
• Comfort working in a partnerships, marketplace or B2B2C context, where you’re building for users you don’t sell to directly.
• Strong facilitation and communication skills, with the ability to hold your own in a room with senior leadership.
• Experience in financial services, savings or fintech.
• Familiarity with referral or affiliate‑style growth models.
• Exposure to enterprise or B2B portal products.

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 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, nursery schemes, home and tech goods.
• Around the World scheme – 3 months work from anywhere scheme.
• 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.
