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.
Implement structured logging, application/API metrics, performance monitoring and operational dashboards.
Use observability platforms such as Grafana, CloudWatch, AppDynamics, Datadog or equivalent.
Diagnose production issues, perform root-cause analysis and implement preventative improvements.
Establish appropriate environment configuration, dependency management and release/versioning practices.

Quality Engineering

Establish automated testing across unit, component, integration, API and end-to-end layers.
Use modern test frameworks such as React Testing Library, Jest/Vitest and Playwright/Cypress or equivalent.
Establish API and frontend/backend contract-testing practices.
Define practical code-quality and test-coverage expectations.
Promote automated quality checks within CI/CD pipelines.

Architecture, SME & Technical Leadership

Serve as the React and full-stack engineering SME across multiple analytics initiatives.
Define and maintain reusable reference architectures, application scaffolding, shared components and engineering standards.
Lead technical design and code reviews across internal and partner/vendor engineering teams.
Evaluate architectural options and make pragmatic decisions covering scalability, maintainability, security, performance and delivery complexity.
Set standards covering coding, branching, testing, security, accessibility, documentation and definition of done.
Guide teams on technical feasibility, estimates, engineering trade-offs and build-versus-buy decisions.
Identify and manage technical debt, modernization opportunities and dependency/lifecycle risks.
Mentor engineers through design reviews, pairing, reference implementations and technical documentation.
Influence teams without direct reporting authority and drive adoption of common engineering standards.
Communicate technical decisions, risks and recommendations effectively to architecture, security, product and senior business stakeholders.

Required Qualifications

Bachelor's degree in Computer Science, Engineering or related field required
9-12 years of professional software engineering experience.
Approximately 5+ years of substantial hands-on experience with React and modern JavaScript/TypeScript development.
Strong knowledge of React architecture, hooks, component design, routing, state/data management and frontend performance.
Demonstrated experience designing and developing backend APIs, preferably using Python/FastAPI.
Proven ownership of end-to-end full-stack applications from architecture and development through testing, deployment and production support.
Strong understanding of REST API architecture and frontend/backend integration patterns.
Strong SQL skills and experience integrating applications with relational databases or cloud data platforms.
Experience implementing authentication and authorization for enterprise applications.
Practical understanding of application security and OWASP-aligned secure development practices.
Hands-on experience with Git, CI/CD, Docker and cloud deployment.
Strong automated-testing discipline across frontend and backend services.
Demonstrated ability to troubleshoot application performance and production issues.
Experience conducting architecture/design and code reviews.
Proven ability to establish engineering standards and influence multiple engineering teams.
Strong communication skills with the ability to translate complex technical topics for non-technical stakeholders.
Experience working within Agile delivery environments.
