Java Backend Engineer

We’re looking for an experienced Backend Engineer to design and build robust, scalable microservices. You’ll work across the full backend stack — from API design through to production-grade integration testing — using modern Java and Spring technologies.

Mobility: Comfortable working from the Glasgow office 2 days per week.

Requirements

Strong hands-on experience with Java 17+ and Spring Boot 3

Proven experience building and maintaining microservices architectures

Practical experience with Kafka (producers, consumers, event-driven patterns)

Strong understanding of REST API design best practices

Proficiency with Gradle for build management

Familiarity with MapStruct and Feign

Working knowledge of domain-driven design (DDD) patterns

An integration-testing mindset — comfortable testing services in realistic, end-to-end scenarios, not just isolated units

Job responsibilities

Design, build, and maintain backend microservices using Java 17+ and Spring Boot 3

Design and implement clean, well-documented REST APIs

Build event-driven services using Kafka for asynchronous communication

Apply domain-driven design principles to structure services around business capabilities

Use MapStruct for clean object mapping and Feign for service-to-service communication

Manage builds and dependencies using Gradle

Write meaningful integration tests (not just unit tests) to ensure real-world reliability

Collaborate with cross-functional teams to deliver high-quality, maintainable code
