Director of Payment Products

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.
