Responsibilities
• Design and deliver full-stack features across Java Spring Boot APIs and TypeScript/React frontends. • Contribute to the EKS/Kubernetes migration and ongoing cloud-native evolution on AWS. • Write clean, well-tested code with SonarCloud quality gates, Trivy security scans, and GitHub Actions CI/CD pipelines. • Work with AWS RDS Aurora (MySQL) and DynamoDB for relational and document storage patterns. • Integrate with third-party platforms (core banking systems, CRM) where relevant to your stream. • Participate in code review, technical design discussions, and architectural decision-making. • Mentor colleagues and share patterns and practices from broader industry experience. • Bring enthusiasm for AI-augmented development — the team actively experiments and values engineers who do the same. • 7+ years of professional software development experience. • Strong proficiency in Java and Spring Boot. • Solid TypeScript and React experience for building complex, data-driven UIs. • Sound understanding of REST API design (OpenAPI/Swagger), microservices, and distributed systems. • Hands-on experience with AWS (EC2, RDS Aurora, DynamoDB, EKS or comparable Kubernetes environments). • Familiarity with CI/CD pipelines using GitHub Actions or Jenkins, Docker, and container security tooling. • Ability to work autonomously in a small, cross-functional team with genuine ownership of outcomes.
