Industry : Fintech / Platform Engineering

Education : B.E. / B.Tech / M.E. / M.Tech in Computer Science or related field.

Role Summary :

We are seeking a high-caliber Java Developer to join our engineering team in Bengaluru.

In this role, you will act as a "Platform Modernization Expert," responsible for migrating legacy C++ frameworks to high-performance Java-J2EE architectures.

You will design, develop, and deploy external-facing, high-volume applications capable of handling massive transaction loads and user clicks.

The ideal candidate is an API-first programmer with deep expertise in the Spring Boot ecosystem and a proven track record of managing CI/CD pipelines for large-scale production environments.

Responsibilities :

- API & Microservices Engineering : Architect and build production-grade RESTful APIs from scratch using the JAVA-J2EE stack and Spring Boot framework.

- Legacy Migration : Lead the technical transition of legacy systems from C++ to Java, ensuring feature parity and improved performance during the migration.

- High-Volume Systems Design : Develop and optimize external applications designed for high-volume transactions, ensuring low latency and high availability for global users.

- Cloud & Platform Onboarding : Participate in cloud onboarding initiatives, deploying services into modern cloud environments and managing platform-wide announcements.

- Database Management : Design and maintain relational database schemas (PostgreSQL, MySQL, etc.) to support complex financial data and transaction history.

- CI/CD Pipeline Management : Own the full software development lifecycle by managing version control and automated deployments using GitHub and other CI/CD tools.

- Automated Testing : Implement rigorous testing protocols using frameworks like TestNG to ensure code reliability and prevent regressions in production.

- Caching & Performance Tuning : Integrate caching frameworks (e.g., Redis, Memcached) to reduce database load and improve application response times for high-traffic events.

- Collaborative Development : Partner with cross-functional teams to translate business requirements into scalable technical solutions, participating in code reviews and architecture planning.

Technical Requirements :

- Core Programming : 1 to 8 years of mandatory experience in JAVA-J2EE and API development.

- Framework Mastery : Strong hands-on experience with Spring Boot and HTTP REST protocols.

- Database Depth : Proficiency in any Relational Database; experience with PostgreSQL or MySQL is highly preferred.

- Version Control : Professional experience with GitHub and managing CI/CD pipelines.

- Scale Experience : Proven background in developing large-scale, external-facing applications with high transaction volumes.

Preferred Skills :

- Legacy Knowledge : Familiarity with C++ to facilitate smoother migrations.

- NoSQL Exposure : Experience with Bigtable or other non-relational storage solutions.

- Fintech Domain : Previous experience building financial or payment-processing systems.

- AI Tooling : Hands-on experience using AI-assisted coding tools to accelerate development workflows.

- Caching : Deep understanding of distributed caching strategies.

Core Competencies :

- Analytical Rigor : A methodical approach to deconstructing legacy C++ code into modular Java services.

- Result Driven : A focus on delivering high-performance applications that handle "clicks and transactions" without failure.

- Adaptability : The ability to pivot between legacy migration tasks and modern cloud onboarding projects.

- Communication Excellence : Clear and concise technical communication for both internal documentation and team collaboration
