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 contemporary, 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. This job was posted by Akshatha M from SenSei Technologies.
