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 honoured 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.

Location: 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. This role is pivotal in helping us overcome the challenges of speed, reliability, and scalability to ensure smooth crypto transactions for our customers.

The Crypto Payments Squad develops and maintains the services that power BVNK’s crypto payment infrastructure. 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.

  • 5+ years experience as a Backend Developer in a similar role, preferably in the FinTech industry.
  • Expertise in Java and Spring Boot.
  • Proven ability to design, architect, debug, test, and create well-documented code.
  • Production experience in asynchronous messaging with microservices.
  • 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.
  • An open and creative environment where you can help us define the future of BVNK, its culture, and its opportunity sets.

How to prepare for a job interview at BVNK

Brush Up on Your Coding Skills

For a full-time software engineering role, it's crucial that we stay sharp with our coding abilities. Expect technical questions that might involve solving problems on the spot or discussing algorithms. Practise on platforms like LeetCode or HackerRank to get comfortable with the types of questions that often come up.

Know Your Tools and Frameworks

Make sure we’re well-acquainted with the tools and technologies listed in the job description. Familiarise ourselves with any specific frameworks or programming languages mentioned. If BVNK uses React or Node.js, for instance, be ready to discuss how we’ve used them in previous projects or coursework.

Make sure we can talk through our thought process for each project, especially the challenges we faced and how we solved them—this shows our problem-solving skills in action.

Prepare for Behavioural Questions

While technical skills are key, full-time positions also require cultural fit. Be ready to discuss our previous experiences and how we handle teamwork, conflict, and deadlines. Brush up on the STAR method—Situation, Task, Action, Result—to clearly articulate our past experiences when discussing how we've contributed to a team.
