Backend Engineer — Java

THE ROLE

• You will design, develop, test, deploy and maintain secure, scalable backend applications — the business logic, APIs, integrations and data processing behind our customer-facing products. The work is judged on what survives production: correctness under load, safety under failure, and code the next engineer can maintain. You will report to the Chief Technology Officer.

WHAT YOU WILL DO

• Design and develop secure, scalable, maintainable APIs and application business logic in Java.
• Design database structures and data-access components, and optimise application and database interactions.
• Apply transaction and concurrency management, and idempotency where an operation must not run twice.
• Build applications that handle retries, duplicate requests and partial failures safely.
• Implement authentication, authorisation and application-security controls, and protect sensitive data in transit, at rest and in logs.

WHAT WE ARE LOOKING FOR

• Substantial hands-on experience building and maintaining production backend services in Java.
• Spring Boot or an equivalent framework, relational databases and SQL, and REST API design.
• Understanding of asynchronous and event-driven architecture, caching, and application security.
• Git, automated testing, containerisation and modern deployment.
• A first degree in computer science, engineering or a related discipline, or demonstrable equivalent experience.
• Experience in financial services or payments — where correctness under failure matters more than speed of delivery — is an advantage.
