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.
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
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
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.
