Do you enjoy building robust, scalable systems that handle real complexity - and doing it with modern Java and AWS?

My client is looking for a Staff Java Engineer to play a key role in designing and delivering high-performance backend services in a cloud-first environment. This is an opportunity to work on meaningful, production-critical systems alongside experienced engineers who care about quality, scalability and clean design.

The team is flexible by default - you’re welcome to work fully remote, or take advantage of their excellent office in Belfast if you prefer a hybrid setup. There’s no fixed expectation; it’s about what works best for you.

What you’ll be doing

• Designing, building and maintaining scalable backend services using Java
• Working heavily with AWS (e.g. EC2, ECS/EKS, Lambda, S3, RDS, CloudWatch)
• Contributing to system design discussions and technical decision-making
• Improving performance, reliability and observability of distributed systems
• Collaborating closely with product, DevOps and engineering peers
• Mentoring more junior engineers and setting best practices

What we’re looking for

• Strong commercial experience as a Senior Java Engineer
• Deep knowledge of modern Java (Java 11+)
• Hands-on experience building and running systems on AWS
• Experience with microservices, REST APIs and distributed architectures
• Solid understanding of databases (SQL and/or NoSQL)
• Comfortable working in CI/CD-driven environments
• A proactive mindset and strong problem-solving skills

Nice to have

• Experience with Spring / Spring Boot
• Infrastructure as Code (Terraform, CloudFormation)
• Containerisation (Docker, Kubernetes)
• Experience in high-throughput or mission-critical systems

This role would suit someone who enjoys ownership, technical challenge and having a real impact on the systems they build.

If you have any further questions on the role, please feel free to reach out to Brendan McCrory directly
