Job description

Founded in 2017 as an OTC digital asset trading desk serving high-net-worth individuals, corporates, and institutional clients globally, ONE.io quickly recognised a broader challenge: clients in underserved sectors faced immense difficulty managing liquidity and moving fiat funds. To solve this, we expanded into comprehensive payment services, securing our FCA Payment Institution licence in 2020 and launching our proprietary platform in 2021.

Today, ONE.io provides a unified financial services solution for global clients across diverse verticals. Powered by an expansive banking network and robust regulatory framework, our platform helps businesses manage multi-currency cash positions and handle complex cross-border transactions through two core propositions:

• ONE.io Connect: Essential treasury and operational tools, including multi-currency business accounts, global payments, and spot FX.
• ONE.io Fusion: 24/7 digital-asset OTC and eOTC platform, custody, and a crypto payment gateway.

Through a single onboarding journey, clients access a central hub for their global operations. This includes named IBANs in multiple currencies, 24/7 liquidity and trading, and direct access to core payment rails such as SWIFT, SEPA, Faster Payments, and CHAPS.

The ONE.io Group is very culture-driven and employees live by our values which include:

• Ingenuity: Constantly improving with creativity and confidence
• Integrity: Brave and tenacious in pursuit of equality
• Unity: A team empowered by shared beliefs and commitment
• Dedication: Intuitive to our customers needs and accountable for our actions

Role Overview

London (hybrid, 2 days a week in the office) | Frequent travel | Reports to the Chief Revenue Officer

Most customer success jobs are support with a nicer title. This one isn't. You'll own ONE.io's existing book of business: the banking, payments and digital-asset relationships behind clients across iGaming, digital assets, family offices and payment companies, all over the world. Your job is to grow it, fast. Operations handles the noise. You handle the revenue.

You'll lead Account Management, the team that owns the commercial relationship with every existing client. Most of our revenue comes from the book we already have, and much of our growth has to come from it too. That makes this one of the most important seats in the business. You'll lead a team of two experienced account managers and sit on the commercial leadership team alongside Sales, Sales Trading and Marketing.

Why now?

We've restructured our commercial team for the next phase of growth, and it's time to take the company to the next level. We're expecting hyper‑growth from the existing book. You'll help set the target, and then you'll own it.

Key Responsibilities

• Revenue from the existing book: own retention, expansion and net revenue growth across every client segment. This is a number, not a feeling.
• Cross-sell and upsell: take clients from one product to the full platform, across trading volume, Gateway, custody, Yield and treasury.
• Top accounts: build senior relationships with the CFOs, treasurers and founders at our largest clients, backed by account plans and quarterly business reviews that drive decisions.
• Commercial terms: negotiate pricing, minimums, renewals and contract updates, well and on time.
• Customer health and churn: spot at‑risk accounts early and run a save playbook that works.
• Team performance: coach and develop the team, set clear targets, and run a tight weekly pipeline and forecast in HubSpot.
• The line between commercial and service: keep the team focused on growth, work with Operations so service and admin land where they belong, and fix the processes that pull account managers into support.
• Being in the room: meet clients around the world and represent ONE.io at the industry's major events.

Skills and Experience

• A revenue leader first. You chase the extra dollar, you'd rather be in front of a client than behind a dashboard, and when something breaks you fix it in the room.
• Experience leading account management at a payments company, bank or digital‑asset business with a significant iGaming client base. Experience at a direct competitor is a strong plus.
• All four boxes ticked: banking, payments, crypto, and a highly regulated environment.
• A track record of carrying a revenue number for an existing book, with the results to show for it: net revenue retention, expansion revenue, accounts saved.
• Confidence with CFOs, treasurers and founders, and a real understanding of how money moves: FX, settlement, accounts and stablecoins.
• An entrepreneurial mindset. You like building, you're comfortable with ambiguity, and you move at scale‑up pace.
• Experience building and coaching a team, with pipeline discipline and forecasts that land.

What you’ll get in return:

• Vitality Health Insurance
• Enhanced Parental Leave
• Perks at Work Reward Platform
• Unlimited holiday policy
• Continuous learning and development opportunities
• Competitive remuneration
