## Description

Experience: 9–12 years of software engineering experience, with substantial hands-on experience developing modern React applications Location: Mumbai | Hybrid Role Purpose We are seeking a highly experienced, hands-on Full-Stack Engineering and React SME to provide technical leadership for modern web-based analytics applications across the Analytics Gateway portfolio. The role combines hands-on engineering, solution architecture, and technical leadership . The successful candidate will build production applications while establishing reusable engineering patterns, standards and platform capabilities that can be adopted across multiple project teams. The individual will be expected to operate across the full application lifecycle, spanning React/TypeScript front-end engineering, Python backend services, API integration, enterprise authentication and authorization, Snowflake connectivity, automated testing, CI/CD, cloud deployment, security and production observability . This is not a traditional people-management position or a pure front-end role. It requires a senior engineer who can remain hands-on while acting as a technical SME and design authority across multiple initiatives. Key Responsibilities Front-End Engineering Design and build scalable, production-grade applications using React and TypeScript . Establish component-driven UI architectures supporting reusable components, modular development and consistent user experiences. Implement robust approaches for routing, client and server state, asynchronous data retrieval, error/loading states and caching. Build responsive, accessible applications supporting desktop and tablet experiences. Develop data-intensive interfaces using visualization libraries such as Highcharts, ECharts, D3 or equivalent . Optimize application performance through appropriate use of lazy loading, code splitting, memoization, virtualization, pagination and caching. Establish reusable design systems, component libraries, and Figma-to-code patterns across multiple applications. Apply appropriate accessibility standards such as WCAG 2.1 AA . Backend & API Engineering Design, develop and maintain backend services using Python with Flask and/or FastAPI . Design well-structured REST APIs covering contracts, schema validation, versioning, pagination, standardized error handling and API documentation. Own frontend/backend integration end to end, including API contracts, schema evolution and backward compatibility. Integrate applications securely with enterprise platforms and cloud data services. Develop performant data-access patterns for Snowflake and other cloud data platforms , with appropriate consideration for connection management, query performance and caching. Maintain appropriate separation between presentation, service/business logic and data-access layers. Security & Enterprise Engineering Apply secure-by-design engineering principles throughout the application lifecycle. Implement enterprise authentication patterns utilizing SSO, OAuth2/OIDC and/or SAML . Design application authorization using RBAC and entitlement-based access controls , ensuring protected resources and data permissions are enforced server-side or at the appropriate data/service layer. Apply OWASP-aligned secure coding practices covering injection, XSS, CSRF, authentication/session risks and dependency vulnerabilities. Ensure credentials, tokens and secrets are managed securely and never exposed within client-side code. Participate in SAST/SCA/DAST scanning, dependency management, vulnerability remediation and application-security reviews. Implement appropriate audit logging and access traceability for enterprise applications. Cloud, DevOps & Production Engineering Containerize web applications and backend services using Docker . Build and maintain automated CI/CD pipelines using GitHub Actions, GitLab CI, Azure DevOps or comparable platforms. Deploy and support applications on AWS/cloud-based container environments .
