Senior Java Backend Engineer

We are looking for an experienced Java backend engineer 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 build resilient APIs, set up event-driven streams using Apache Kafka, optimise sub-second caching with Redis, and maintain 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:

• 1 to 3 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.
