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 environment

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

- Solid 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
