Director of Payment Products in London

About Notabene

Notabene is building infrastructure that's transforming how money moves in the digital economy. We're evolving beyond our compliance foundations to enable the next generation of digital financial services between regulated institutions with unprecedented efficiency. With nearly 50 employees across 14 countries and having recently closed our Series B round last November with support from leading investors including Y Combinator, DRW, F-Prime, Jump Capital, Castle Island, and Green Visor Capital, we're looking for people like you to help shape the future rails of the crypto industry.

The impact you will have

Notabene Flow is live. The first version of our payment authorization product is in customers' hands - and now the real work begins. As Director of Payment Products, you'll lead what Flow becomes: defining the features, workflows, data requirements, and overall product experience that turns our early release into the go-to payment authorization layer for institutions moving stablecoins and digital assets at scale. Notabene's platform is unified - the same infrastructure powers both Transact (our compliance product) and Flow. Engineering owns the platform. Your job is to be the expert voice for Flow's needs within that shared system: clear on the jobs to be done, rigorous in how you articulate requirements, and skilled at making the case for Flow priorities in a context where Transact's needs matter equally. You'll work directly with engineering, our Product Designer, and the GTM team - owning the why of what gets built while respecting engineering's authority over the how and when. You'll report directly to and work closely with the CEO on Flow's strategy and market positioning. This is a high-visibility role at the heart of where Notabene is going - the person who takes it will have direct access to the company's strategic direction and a seat at the table where the most important product decisions get made. This is an exciting opportunity to join a critical function that will shape our growth and expansion into new markets.

Within a year you are successful if...

• Flow has active, paying customers generating consistent and growing transaction volume, with clear evidence of product-market fit in at least one payment vertical.
• Engineering has a clear, trusted view of Flow's feature and data requirements, and Flow priorities are well-represented and well-understood within the shared platform roadmap.
• Flow's messaging and value proposition are sharp enough that a business-side buyer at a bank or fintech can immediately understand why it matters to them.
• You've built a prioritized backlog grounded in deep customer insight that the engineering team can confidently act on within the platform's architecture.

What you will be doing

• Lead the definition of Flow's features, workflows, and data requirements - from customer discovery through to prioritization and post-launch measurement.
• Spend significant time with existing customers, prospects, and partners to develop a deep understanding of the jobs to be done in payment authorization across different verticals.
• Articulate clear, well-reasoned requirements for Flow within the shared Notabene platform - making the case for Flow's priorities in a context where engineering balances Flow and Transact needs simultaneously.
• Work hand-in-hand with the engineering team as the owner of the why, while they own the how - giving them the customer and market context they need to make good platform decisions on Flow's behalf.
• Collaborate with the Product Designer to ensure Flow's user experience is clear, efficient, and appropriate for the institutional users we serve.
• Partner with the GTM team to develop positioning, messaging, and go-to-market plans that connect Flow's capabilities to the needs of business-side buyers.
• Develop and maintain deep knowledge of the stablecoin and digital payments landscape - including competitor moves, partner capabilities, and regulatory developments.
• Define and track the metrics that tell us whether Flow is succeeding: transaction volume, customer retention, time-to-first-value, and expansion revenue.

What you bring

• 6+ years in product management or product strategy, with the majority focused on payments, stablecoin infrastructure, or digital financial services.
• Proven experience owning a payments product through its early stages - you've taken something from initial release to real commercial traction and can speak specifically about how you did it.
• Deep understanding of payment flows, transaction authorization mechanics, and the institutional ecosystem (PSPs, exchanges, fintechs, banks).
• Demonstrated ability to work directly with engineering teams, earn their trust as a peer, and drive alignment on roadmap priorities without hierarchical authority.
• Strong instincts for customer discovery - you know how to run conversations that surface genuine insight rather than surface-level feedback.

Nice to have

• Familiarity with low-level payment processing standards such as ISO 20022, ACH, or ISO 8583 - and how they fit within the broader institutional payment ecosystem.
• Background in compliance-adjacent products or regulated financial infrastructure.
• Experience building or contributing to a product-led growth motion in a B2B financial services context.
