Job details:
We are looking for an experienced Senior Java Backend Engineer (2 to 5 years of experience)to join our technical delivery team on a critical platform-modernisation project for a leading financial client.
In this role, you will play a hands-on technical role in re-engineering the client's legacy platform into a modern, high-throughput custom Spring Boot microservices architecture for their Loan Management System (LMS). You will be responsible for building resilient APIs, setting up event-driven streams using Apache Kafka, optimising sub-second caching with Redis, and maintaining strict ACID database consistency across high-volume loan calculations and repayment transactions.
Responsibilities
- Hands-on Development and Architecture (70%+ time): Design, write, and maintain scalable Java code, driving core component design, API modelling, and rigorous code reviews for the client platform.
- Legacy-to-Microservices Modernisation: Work closely with the client's product and architecture teams to extract monolithic legacy components (disbursement engines, EMI schedules, interest calculators, and repayment workflows) into decoupled Spring Boot microservices.
- Event-Driven Architecture: Build reliable, asynchronous messaging pipelines using Apache Kafka for real-time transaction streaming and system integration across internal and partner services.
- Database and Caching Performance: Architect strict ACID-compliant schemas using MySQL / PostgreSQL to preserve data integrity across financial ledgers. Deploy Redis for distributed locking, rate-limiting, and caching.
- Client Engagement and Quality: Ensure high standards of code quality, unit/integration test coverage (JUnit/Mockito), and technical documentation in alignment with client standards and regulatory mandates.
Requirements
- 2 to 5 years of core backend software engineering experience using Java (11/17+) and Spring Boot(Spring Data JPA, Spring MVC, Spring Security).
- Proven track record in designing, building, and deploying RESTful microservices in high-throughput environments.
- Practical hands-on experience with Apache Kafka (pub/sub messaging, topic partitioning, DLQ handling).
- Hands-on proficiency with Redis for distributed caching and performance optimisation.
- Solid experience with relational databases (MySQL or PostgreSQL), including schema design, query tuning, indexing, and strict ACID transactional controls.
Nice-to-Have Skills (Bonus Points)
- Direct experience working on Loan Management Systems (LMS)within banking, fintech, or NBFC sectors.
- Exposure to distributed SQL databases(e. g., CockroachDB).
- Familiarity with RBI Digital Lending Guidelines or financial regulatory and audit frameworks.
- Basic working knowledge of Docker, Kubernetes, and CI/CD deployment workflows.
