Software Engineer

At Kroo Bank, we’re building the future of banking with modern technology and a culture that values innovation, collaboration, and impact. Unlike traditional banks or outsourcing firms, our engineers shape real products used by thousands of customers every day in the UK.

Why join us?

• Be part of a new generation UK bank. Kroo was awarded a full UK banking licence in 2022, making us one of only a handful of fintechs to achieve this milestone.
• We’re one of the fastest-growing banks in the UK, reaching £1 billion in deposits faster than any of our peers, with 200,000+ customer accounts and growing every day.
• Work with a modern stack: Clojure, React Native, Kafka, AWS, Docker, Terraform.
• Practise or learn functional programming (we’ll support you even if you’re new to it).
• Be part of a cross-functional squad where engineers, designers, testers and product managers collaborate as equals.
• Permanent employment contract in Romania, 100% remote, with flexible hours and a healthy work-life balance.
• Competitive salary and stock options, so you share in the success of the company.
• Join a young, dynamic, and mission-driven organisation where your work directly shapes how people bank in the UK.
  
  

What you’ll do

• Build and deliver new features end-to-end, from idea to production, in a modern CI/CD environment.
• Work across the stack including backend microservices (Clojure, Kafka, AWS, Postgress) to frontend (React Native). We offer opportunities to specialise or grow as a full-stack engineer.
• Collaborate daily with product, design, and engineering colleagues to ship customer-facing features in an agile environment based on Kanban and XP practises such as pair programming and test driven development.  
• Write clean, maintainable, and testable code, and participate in code reviews.
• Contribute to system design discussions and bring ideas to improve scalability and resilience.
• Keep learning, diving deeper into banking products, functional programming, mobile frameworks, or cloud infrastructure.
• Optionally, contribute back to open source and share knowledge with the wider engineering community.

What we’re looking for

• Professional experience in backend or mobile development (Clojure, Java, Kotlin, JavaScript/TypeScript, Swift, or any functional language is a plus).
• Interest in learning Clojure and functional programming.
• Familiarity with modern cloud environments (AWS preferred).
• Good communication skills in English and ability to work effectively in a distributed Agile team.
• A collaborative mindset and passion for building high-quality products
• Experience working in banking, fintech, or other highly regulated industries — understanding payments, compliance, or financial products is a plus.
