- Design, build, and maintain Java applications and microservices that underpin critical financial services and core business platforms.
- Build and manage integrations with core banking platforms, payment gateways, third-party financial systems, and enterprise middleware using REST and SOAP protocols.
- Implement and enforce secure coding standards across backend services, including OAuth 2.0, JWT authentication, SSL/TLS management, and data encryption.
- Provide technical leadership across the software delivery lifecycle, from architecture and development through integration, testing, deployment, and production support.
- Contribute to CI/CD pipeline development, containerization using Docker, and Kubernetes-based deployments to improve release quality, operational efficiency, and platform resilience.
- Maintain technical documentation, architecture decision records, support artefacts, and other engineering documentation.
- Conduct code reviews, establish engineering standards, and mentor junior and mid-level developers to strengthen technical capability across the team.
- Collaborate closely with business analysts, product owners, compliance officers, architects, and operations teams to translate business and regulatory requirements into technical solutions.
- Participate actively in Agile delivery ceremonies, including sprint planning, backlog refinement, stand-ups, and retrospectives.
- Support post-production stability through troubleshooting, incident resolution, root cause analysis, and continuous improvement of backend performance.
Mobile Development (Advanced)
- Support the design, development, and maintenance of mobile applications across Android or iOS using Kotlin or Swift.
- Contribute to the delivery of intuitive, high-performing, and reliable mobile user experiences aligned with business and customer needs.
- Collaborate with product, design, backend, and cross-functional engineering teams to implement and enhance mobile features.
- Write clean, maintainable, and reusable code in line with established mobile engineering standards and best practices.
- Assist in troubleshooting, debugging, and resolving mobile application issues, including performance, integration, and device compatibility challenges.
- Support the integration of mobile applications with backend APIs, third-party services, and enterprise platforms.
- Participate in code reviews, testing, and release activities to help ensure quality, stability, and maintainability of mobile solutions.
Technical Competencies
- Deep expertise in Java, including Java 8+ and Java 17, with a strong track record using Spring Boot.
- Working knowledge of Kotlin or Python.
- Extensive experience with Spring Cloud, Spring Security, and Spring Data JPA.
- Strong architectural understanding of microservices, distributed systems, and modern backend design patterns.
- Proven experience with RESTful and SOAP-based APIs and event-driven architectures using Kafka.
- Advanced knowledge of relational databases (PostgreSQL, MySQL, Oracle) and NoSQL technologies (Redis, MongoDB).
- Experience with Docker, Kubernetes, and CI/CD tools such as Jenkins and GitLab CI/CD.
