Java Developer

We are seeking a highly skilled and motivated Java Developer with strong expertise in Amazon Web Services (AWS), Spring Boot and microservices to join our dynamic engineering team. In this role, you will be responsible for designing, developing, and deploying scalable backend services and microservices that power our core applications. You will collaborate closely with cross-functional teams, including front-end developers, DevOps engineers, and product managers, to deliver robust, high-performance, and cloud-native software solutions.

Responsibilities:

• Application Development: Design, build, and maintain high-performing, reliable, and secure Java-based applications and microservices using the Spring Boot framework.
• Cloud Architecture: Architect, deploy, and maintain cloud-native applications on AWS, utilising services such as EC2 S3 Lambda, RDS, DynamoDB, API Gateway, and ECS/EKS.
• API Design: Develop and document robust RESTful APIs and web services for seamless integration with front-end applications and third-party systems.
• Containerisation and Orchestration: Package applications using Docker and manage containerised deployments using Kubernetes. Ensure seamless scaling and self-healing of services.
• Database Optimisation: Design effective data models and optimise database interactions using SQL (e. g., PostgreSQL and MySQL) and NoSQL databases, alongside ORM tools like Hibernate/JPA.
• Code Quality and Testing: Write clean, modular, and testable code. Implement comprehensive unit, integration, and end-to-end tests using frameworks like JUnit and Mockito.
• DevOps and CI/CD: Collaborate with operations teams to build and maintain automated CI/CD pipelines (e. g., Jenkins, GitHub Actions, and AWS CodePipeline) and support containerisation efforts using Docker and Kubernetes.
• Troubleshooting and Performance: Monitor system health, identify bottlenecks, debug production issues, and implement performance-tuning strategies in distributed systems.
• Collaboration and Mentorship: Participate actively in Agile/Scrum ceremonies, conduct thorough peer code reviews, and help mentor junior engineering staff.
• Observability and Monitoring: Implement distributed tracing, central logging, and monitoring (using tools like AWS CloudWatch, Datadog, Prometheus, or Grafana) to ensure system reliability and rapid debugging.

Requirements:

• Experience: 4-10 years of professional software development experience focusing on backend engineering.
• Core Java: Deep understanding of Java (version 17 or higher), Object-Orientated Programming (OOP) principles, design patterns, and multithreading.
• Spring Ecosystem: Extensive hands-on experience with Spring Boot, Spring Core, Spring MVC, Spring Data JPA, and Spring Security.
• AWS Expertise: Proven experience designing and implementing solutions on AWS. Familiarity with cloud architecture best practices, IAM security, and serverless computing.
• System Architecture: Strong background in microservices architecture, distributed systems, and API-first design methodologies.
• Version Control: Proficiency with Git and modern collaborative development workflows.
• Cloud-Native Mastery: Proven understanding of cloud-native design patterns (e. g., circuit breaker, service discovery, and API gateway), microservices architecture, and 12-factor methodologies.
• Containers and Orchestration: Strong practical experience with Docker and Kubernetes (K8s).

Preferred Skills (Nice-to-Have):

• AWS Certifications (e. g., AWS Certified Developer - Associate, AWS Certified Solutions Architect).
• Experience with event-driven architecture and message brokers (e. g., Apache Kafka, RabbitMQ, and Amazon SQS/SNS).
• Knowledge of Infrastructure as Code (IaC) tools like Terraform or AWS CloudFormation.
• Familiarity with modern front-end frameworks (e. g., Angular, React, or Vue.js ).
• Understanding of caching solutions (e. g., Redis and Memcached).
