Project Description:

You will join a long-term, enterprise-scale project for a global client in the investment banking domain. The project focuses on building and evolving a set of mission-critical backend services that support complex business workflows, regulatory processes, and system integrations across the bank’s ecosystem.

The platform is based on a distributed microservices architecture, leveraging Spring Boot, event-driven communication, and BPM-driven process orchestration. The system operates in a cloud-enabled, containerized environment, with a strong emphasis on security, scalability, resiliency, and maintainability.

You will work closely with architects, QA engineers, DevOps, and business stakeholders in an agile setup, contributing not only code but also technical direction, best practices, and mentoring.

• Ensure high standards of code quality by applying SOLID principles, Clean Code, and design patterns

• Write and maintain comprehensive unit and integration tests using JUnit, TestNG, Mockito, and WireMock

• Work with relational and document databases such as PostgreSQL, MongoDB, and Azure Cosmos DB

• Implement security and authentication mechanisms using OAuth2, JWT, and Spring Security

• Collaborate with DevOps teams on containerization and deployment using Docker and Kubernetes

• Participate actively in agile ceremonies (refinement, planning, reviews, retrospectives)

• Provide technical guidance, perform code reviews, and advocate for engineering best practices

• Collaborate closely with cross-functional teams, including QA, DevOps, and product owners
