Role Purpose Deliver high-quality Java-based services and cloud-hosted solutions on AWS. Contribute to design, development, testing, and optimisation of digital applications while following established engineering standards. Support senior engineers, collaborate with multidisciplinary teams, and ensure services are secure, maintainable, and aligned to DDaT delivery principles. Key Responsibilities Software Development Develop Java microservices using Spring Boot and modern engineering practices. Implement RESTful APIs, service integrations, and reusable components. Write clean, maintainable, well-tested code following established coding standards. Cloud Engineering (AWS) Build and deploy cloud-native solutions using core AWS services (e.g., Lambda, ECS, API Gateway, DynamoDB, S3, RDS). Contribute to cloud architecture discussions and implement best practices for security, scalability, and observability. Quality Engineering Write automated unit, integration, and functional tests. Contribute to code reviews, defect resolution, and performance improvements. Support continuous integration and continuous deployment activities. Technical Collaboration Work with senior developers, DevOps engineers, QA and Product teams to deliver secure and reliable services. Participate in Agile ceremonies (stand-ups, planning, refinement, retros). Provide technical input into design decisions and documentation. Operational Support Support environments, deployments, and troubleshooting. Help maintain service stability using monitoring and logging tools. Essential Skills (Must Have) Strong Java development experience, preferred Java 17. Experience with Spring Boot, REST APIs, and microservice architectures. Hands-on exposure to AWS services in real delivery environments. Knowledge of CI/CD tools (GitHub Actions, Jenkins, GitLab CI, etc.). Good understanding of testing practices (JUnit, Mockito, integration tests). Familiarity with containerization (Docker) and basic cloud networking concepts. Strong problem-solving skills and ability to work independently within guidelines. Desirable Skills (Nice to Have) Infrastructure as Code experience (Terraform, AWS CDK, CloudFormation). Exposure to event-driven systems (Kafka, SNS/SQS, Kinesis). Experience with monitoring/observability tools (ELK, CloudWatch, Grafana, OpenTelemetry, Splunk). Familiarity with security best practices and OWASP principles. Experience working on public-sector or regulated projects. Experience Profile Practical experience delivering Java services in a cloud or microservices environment. Demonstrated contributions to Agile teams (Scrum/Kanban). Experience supporting CI/CD pipelines and DevOps practices. Exposure to collaborative delivery with Product, QA, DevOps and Architecture teams. Ways of Working Works under general direction; receives guidance on complex tasks but handles routine work independently (aligned with SFIA Level 4 expectations). Actively contributes to knowledge sharing, documentation, and continuous improvement. Communicates clearly with technical and non-technical colleagues.
