Senior Software Engineer; Backend): Crypto

Poland

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

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, Lian Lian 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 stable coins 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 Linked In as one of the Top 20 Startups in the UK in 2024.

We offer a Hybrid/Remote working policy.

We’re looking for a talented Software Engineer to join our team. Our goal is to build seamless cross‑border payments involving both crypto and fiat currencies.

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.
