React Frontend Development (Primary Focus)

- Architect, build, and maintain complex React applications — dashboards, analytics platforms, internal tools, and customer-facing products

- Develop responsive, mobile-first UIs optimized for tablet (iPad) and desktop with pixel-perfect execution

- Build rich data visualizations using D3.js, Recharts, Chart.js, or custom SVG/Canvas components

- Implement advanced state management patterns using Redux Toolkit, Zustand, React Query, or Context API

- Create reusable, well-documented component libraries with design system integration (Tailwind CSS, Styled Components, or CSS Modules)

- Optimize frontend performance: code splitting, lazy loading, memoisation, virtual scrolling, bundle analysis

- Write comprehensive tests using Jest, React Testing Library, and Cypress for E2E testing

- Implement real-time features using WebSockets, Server-Sent Events, or polling strategies

API Design & Backend Development

- Design and build RESTful APIs using Node.js (Express/Fastify) or Python (FastAPI/Flask) following OpenAPI specifications

- Develop GraphQL APIs where appropriate for complex data querying needs

- Implement authentication and authorization (OAuth 2.0, JWT, RBAC) for secure API access

- Build middleware for logging, rate limiting, caching, error handling, and request validation

- Design database schemas and write efficient queries (PostgreSQL, MongoDB, or similar)

- Implement API versioning, pagination, filtering, and search capabilities

- Build and maintain microservices or serverless functions (Azure Functions / AWS Lambda)

- Create API documentation using Swagger/OpenAPI and maintain developer-facing docs

Integration & Data Layer

- Integrate frontend applications with data platforms (Databricks, data warehouses, data lakes) through API layers





- Build data ingestion endpoints that accept, validate, transform, and store incoming data

- Work with data engineers to consume curated datasets and serve them through optimized APIs

- Implement caching strategies (Redis, CDN, browser cache) for high-performance data delivery

- Connect to third-party services and APIs (payment gateways, CRM, loyalty platforms, analytics tools)

AI / LLM Integration

- Build conversational AI interfaces (chatbots, knowledge agents) using LLM APIs (OpenAI, Anthropic, Azure OpenAI)

- Implement RAG (Retrieval-Augmented Generation) patterns for document Q&A; and contextual search

- Create prompt engineering frameworks and manage AI response streaming in React UIs

DevOps & Delivery

- Set up and maintain CI/CD pipelines (GitHub Actions, Azure DevOps, GitLab CI)

- Containerize applications with Docker and deploy to Kubernetes or cloud-managed services

- Implement monitoring, alerting, and observability (Datadog, New Relic, or Application Insights)

- Conduct code reviews, mentor junior developers, and drive engineering best practices

Requirements

Must have skills

- 5–7 years of professional full stack development experience in a product engineering workplace

- Expert-level React.js (4 years): hooks, context, suspense, server components, performance patterns

- Robust TypeScript proficiency — type-safe component development, generics, utility types





- Production experience building and consuming REST APIs (Node.js with Express/Fastify or Python with FastAPI)

- Solid database skills: PostgreSQL or MySQL (schema design, indexing, query optimization) and/or MongoDB

- Experience with modern CSS: Tailwind CSS, CSS Modules, or Styled Components for scalable styling

- Proficiency with Git, branching strategies, PR workflows, and collaborative development

- Experience with cloud platforms: Azure (preferred) or AWS — app hosting, serverless, storage, CDN

- Strong understanding of web security: CORS, XSS, CSRF, CSP, authentication flows

- Experience with Docker containerization and basic Kubernetes or cloud-managed container services

- Familiarity with Agile/Scrum and working in cross-functional, distributed teams

Good To Have Skills

- Experience with Next.js (App Router, SSR, ISR, API routes) or Remix

- GraphQL development experience (Apollo Server/Client or similar)

- Data visualization expertise: D3.js, Recharts, Plotly, custom charting

- Experience integrating with LLM/AI APIs and building AI-powered features

- Knowledge of Databricks, Apache Spark, or data lake/warehouse concepts

- Experience with real-time systems: WebSockets, Kafka consumers, event-driven architecture

- Familiarity with design tools (Figma) and design-to-code workflows

- Understanding of retail / e-commerce domain (POS, loyalty, customer analytics)

- Experience with Storybook for component documentation and visual testing

- Knowledge of accessibility standards (WCAG) and internationalization (i18n)

Education

- Bachelor’s or Master’s degree in Computer Science, Information Technology, or related field

- Relevant certifications are a plus: AWS/Azure Developer, Meta React Certification, or similar
