Job description

Responsibilities:

• Hands-on Development and Architecture (30%+ 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 Modernization: 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:

• 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.
