Senior Software Engineer

• Design, develop, and maintain scalable backend applications and services using core Java and the Spring ecosystem (Spring Boot, Spring MVC, Spring Data).
• Lead the design and implementation of microservices architecture, including service decomposition, API contracts, inter-service communication, and data ownership boundaries.
• Build and optimise persistence layers using Hibernate/JPA, ensuring efficient data modelling, query performance, and transaction management.
• Design and expose RESTful APIs following versioning, security, and documentation (OpenAPI/Swagger).
• Apply sound object-oriented design principles, design patterns, and clean-code practices across the codebase.
• Collaborate with DevOps and cloud engineering teams to containerise services (Docker/Kubernetes) and deploy on AWS.
• Ensure application security, performance, and resilience, including authentication/authorization, input validation, caching, and fault-tolerance patterns.
• Write unit tests, participate in peer/code reviews, and adhere to quality standards (SonarQube, CI/CD gates).
• Troubleshoot and resolve production issues, perform root-cause analysis, and drive continuous improvement in reliability and performance.
• Mentor junior engineers and contribute to technical design discussions, architecture reviews, and best-practice adoption across the team.

• 8+ years of software development experience, primarily in core Java (Java 8+) and object-oriented design.
• Proven experience designing and implementing microservices architecture in production environments, including service boundaries, communication patterns (REST/messaging), and data consistency strategies.
• Strong, hands-on expertise with Spring Boot and Spring Framework (Spring Data, Security, and Cloud is a plus).
• Solid working knowledge of Hibernate/JPA for ORM, including entity relationships, query optimisation, caching, and transaction handling.
• Experience with relational databases (MySQL, PostgreSQL, or Oracle) and writing efficient SQL.
• Practical experience with RESTful API design, JSON, and API documentation tools (Swagger/OpenAPI).
• Familiarity with containerisation and orchestration (Docker, Kubernetes) and CI/CD pipelines.

• Experience with unit/integration testing frameworks (JUnit, Mockito) and version control (Git).
• Strong analytical and problem-solving skills, with the ability to work independently and take ownership

• Exposure to AWS cloud services (EC2, ECS/EKS, RDS, Lambda, S3) or other public cloud platforms.
• Experience with event-driven architecture and messaging systems such as Kafka or RabbitMQ.
• Familiarity with distributed systems patterns (circuit breakers, retries, Saga/distributed transactions).
• Working knowledge of NoSQL databases (MongoDB, DynamoDB, Redis).
• Prior experience in an JIRA/Agile/Scrum delivery environment.
• Certifications in Java, AWS, or related technologies.

• Bachelors or Masters degree in Computer Science, Information Technology, or a related field.
