Job Description

About This Role

CodeBridge India is hiring a Java Developer for its Mumbai engineering center. The team develops core banking middleware and payment processing services for financial institutions and fintech clients, and this role involves building and maintaining Java Spring Boot microservices that handle transaction routing, account reconciliation, and regulatory reporting. If you have worked in a transaction-heavy backend environment and know what thread safety and idempotency mean in practice, this team is relevant to your experience.

Role Context

Reporting to the Senior Java Engineer, you will work on a team of seven developers maintaining a suite of financial middleware services. The team deploys to production twice per week and follows a structured code review process before any merge. Business continuity and correctness are the team's primary engineering values — performance is important, but a calculation error in a financial system is far more costly than a slow response time. The role requires discipline around testing, documentation, and structured error handling throughout.

Key Responsibilities

Develop and maintain Java Spring Boot microservices handling banking transaction workflows
Implement idempotent API endpoints for payment initiation and status confirmation flows
Write JUnit and Mockito test suites covering positive paths, edge cases, and failure scenarios
Participate in architecture reviews for new services before development work begins
Investigate and resolve transaction reconciliation discrepancies reported by operations teams
Optimize Hibernate ORM queries and connection pool settings for high-throughput service operations
Maintain API documentation in Swagger and update it with every endpoint change
Support UAT and regulatory testing cycles with test data preparation and environment support

Requirements & Skills

2–4 years of Java development experience with Spring Boot and REST API design
Strong understanding of transaction management, ACID properties, and data consistency guarantees
Practical experience with JPA/Hibernate for ORM-based database interactions
Working knowledge of multithreading concepts and thread-safe design patterns in Java
Familiarity with unit testing using JUnit 5 and Mockito for service-layer isolation
Experience with Oracle or MySQL databases in a production financial services environment
Understanding of OAuth 2.0 or JWT-based authentication for secure API access

Benefits & Work Conditions

Monthly salary of ₹30,000–₹60,000 based on Java depth and financial domain experience
PF, ESI, and full statutory compliance benefits from the first day of employment
Structured mentorship program pairing junior developers with senior Java engineers
Access to BFSI-domain training resources and certification reimbursement for Java credentials
Five-day work week with consistent hours and no weekend work expectations

Who Should Apply

This role suits Java developers who understand that in financial systems, getting it right matters more than getting it done fast. If you have a disciplined approach to testing, enjoy working on systems where correctness is enforced at every layer, and want to build expertise in banking middleware and transaction processing in Mumbai, CodeBridge India is a strong career environment for Java professionals.
