Job description

About us

We believe the next generation of financial services will be powered by stablecoins.

Founded in 2021, our mission at BVNK is to accelerate global money movement.

We’re building stablecoin-native infrastructure so businesses can move value instantly across borders and networks. With global licenses and T1 bank partnerships, we facilitate billions in transactions for enterprise clients like Worldpay, Deel, LianLian Global, and Rapyd.

Our technology is transforming how businesses operate globally by eliminating payment delays, reducing costs, and unlocking trapped capital.

We’re a diverse team spread across EMEA, North America, and APAC, with a shared belief that stablecoins are the new infrastructure layer for financial services, and that BVNK is at the forefront of this shift.

In 2025, we secured strategic investment from Visa, following our $50 million Series B with Haun Ventures, Coinbase Ventures, Scribble Ventures, DRW Venture Capital, Avenir, and Tiger Global. With the backing of these leading investors, we’re accelerating our growth – and we're looking for smart, ambitious people to help us build the future of financial services.

We're incredibly honored to have made Newsweek's list of The Top 100 Global Most Loved Workplaces three years running (most recently in 2025) and to have been recognised by LinkedIn as one of the Top 20 Startups in the UK in 2024.

Our APIs enable businesses to send, receive, and programmatically manage crypto payments 24/7, while integrating with other BVNK domains (e.g., trading) to create a smooth payment flow. Customers rely on our systems to move funds globally with the same ease as traditional finance but with the flexibility of crypto.

Our product and engineering organisation is split into small autonomous squads empowered to own their problem space. You’ll be expected to form strong opinions and execute in a fast but sustainable way, advocating for the simplest solution that achieves the outcomes our customers are looking for.

• Translate from technical to non-technical with stakeholders across the business

• Understanding of common design patterns and principles, and how/when to apply them.
• Demonstrated ability to translate abstract challenges into clear, actionable steps and solutions.
• Experience in taking a product from initiation through the go to market phase, supporting products post launch.
• Good understanding of financial services, particularly in banking, payments or crypto
• Familiarity with distributed ledger technology or blockchain is a plus.
• Participate in out of hours on call rota

What you can expect from us

• Fair and competitive salary at every stage of your growth
• Flexible working hours, with hybrid working at its heart
• A culture built on passionate, growth-minded people
• A flexible approach to holiday
• Opportunities to travel to our offices around the world
