Java Full Stack Engineer

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.

• 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.

• Build and deploy cloud‑native solutions using core AWS services (e.g., Lambda, ECS, API Gateway, Dynamo
  
  DB, S3, RDS).
• Contribute to cloud architecture discussions and implement best practices for security, scalability, and observability.

• Write automated unit, integration, and functional tests.
• Contribute to code reviews, defect resolution, and performance improvements.
• Support continuous integration and continuous deployment activities.

• Work with senior developers, Dev Ops 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.

• Support environments, deployments, and troubleshooting.
• Help maintain service stability using monitoring and logging tools.

• 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 (Git Hub Actions, Jenkins, Git Lab 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.

• Infrastructure as Code experience (Terraform, AWS CDK, Cloud Formation).
• Exposure to event‑driven systems (Kafka, SNS/SQS, Kinesis).
• Experience with monitoring/observability tools (ELK, Cloud Watch, Grafana, Open Telemetry, Splunk).
• Familiarity with security best practices and OWASP principles.
• Experience working on public‑sector or regulated projects.

• Practical experience delivering Java services in a cloud or microservices environment.
• Demonstrated contributions to Agile teams (Scrum/Kanban).
• Experience supporting CI/CD pipelines and Dev Ops practices.
• Exposure to collaborative delivery with Product, QA, Dev Ops and Architecture teams.

• 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.

UK‑based, hybrid working as agreed with the client; BPSS or SC clearance may be required.
