Position Purpose

Design, develop, and maintain robust, scalable Java-based backend services and middle business layer components within enterprise full-stack applications. Own backend architecture decisions, API design, data access patterns, and integration with upstream and downstream systems. Work competently across the existing frontend layer using Angular/TypeScript/React. Bring the depth of an experienced backend engineer with the breadth to contribute across the full stack. Leverage AI-assisted development tools as a standard part of day-to-day engineering practice.

Direct Responsibilities

•    Develop scalable full-stack solutions using Java, Spring Boot, and modern frontend frameworks (React/Angular).

•    Design and optimize high-performance APIs with security, caching, and fault tolerance.

•    Develop robust backend services with efficient database interactions.

•    Build responsive UI with seamless backend integration.

•    Automate CI/CD pipelines for rapid, reliable software delivery.

•    Lead cloud-native deployments with containerization, auto-scaling, and cost optimization.

•    Enforce Quality-first engineering: Unit, integration, and ensure high code quality with SonarQube.

•    Mentor junior developers, conduct code reviews, and drive technical excellence across the team.

•    Collaborate with stakeholders to translate business needs into scalable technical solutions.

Contributing Responsibilities

•    Contribute to technical design discussions and architecture decisions, particularly around API design, data layer, and system integration

•    Participate in code reviews and enforce clean code and quality gate standards

•    Support knowledge transfer and capability building within the India Solutions team

•    Collaborate with cross-functional teams (frontend, QA, infrastructure) on integration and delivery

•    Contribute to improving DevSecOps maturity and SDLC practices within the team

Technical & Behavioral Competencies

•    Autonomy & Ownership: Ability to work autonomously and take end-to-end ownership of backend components

•    Industry Expertise: Experience in large-scale regulated enterprise environments (banking/financial services preferred)

•    Collaboration & Communication: Strong collaborative and communication skills to work in a global team

Specific Qualifications

Experience Level: 5+ years

•    4+ years with Java backend development at enterprise scale

•    3+ years with Spring Boot/Spring MVC in production environments

•    Demonstrated good experience across the listed Technical skills.

•    Familiarity with frontend integration using Angular/TypeScript/React

•    Experience with legacy system refactoring to target architecture

•    Active use of AI coding assistants in daily workflow

Domain Experience

•    Banking, financial services, or similarly regulated enterprise environments preferred

•    Experience in GCC or offshore delivery models advantageous

•    Exposure to high-volume, high-availability backend systems
