Senior Java Engineer

Do you enjoy designing and building scalable backend systems in the cloud - with Java at the core and AWS powering it all?

My client is looking for a Senior Java Engineer to join a highly capable engineering team working on modern, cloud-native systems. This role offers real ownership, technical depth and the chance to shape how systems are built and run on AWS.

What you'll be doing

• Designing, developing and maintaining backend services using Java

• Building and operating cloud-native solutions on AWS

• Working with services such as EC2, ECS/EKS, Lambda, S3, RDS/DynamoDB and CloudWatch

• Contributing to architectural decisions and cloud best practices

• Improving system scalability, performance and resilience

• Working closely with DevOps, product and engineering teams

• Mentoring junior engineers and raising engineering standards

What we're looking for

• Strong commercial experience as a Senior Java Engineer

• Deep knowledge of modern Java (Java 11+)

• Hands-on AWS experience in production environments

• Experience designing and supporting distributed systems and microservices

• Strong understanding of RESTful APIs and event-driven architectures

• Experience with CI/CD pipelines and cloud-based deployments

• A proactive, problem-solving mindset

Nice to have

• Spring / Spring Boot

• Infrastructure as Code (Terraform, CloudFormation)

• Containerisation (Docker, Kubernetes)

• Experience in high-availability or high-throughput environments

This role would suit a senior engineer who enjoys building reliable cloud systems and taking ownership from design through to production.

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