Description

The Senior React / Next.js Engineer is a hands-on consultant responsible for designing and delivering scalable enterprise web applications.

This role requires advanced experience with React, Next.js, TypeScript, API integration, and modular application architecture. The engineer will also support Intelligent Document Processing solutions and should understand how Python, AI, and Large Language Models can be used in document workflows.

What You’ll Do

Design, build, test, and deploy enterprise applications using React, Next.js, and TypeScript. Create modular, reusable, and maintainable application architectures. Build shared components, hooks, services, utilities, and design-system patterns. Design scalable approaches for routing, state management, data fetching, forms, validation, and error handling. Integrate applications with APIs, authentication systems, enterprise data sources, and document-processing services. Build document upload, review, correction, approval, and exception-management experiences. Use Python to support document ingestion, extraction, validation, transformation, and integration. Apply AI and LLM capabilities to document classification, extraction, summarization, and validation where appropriate. Improve existing codebases by reducing duplication, tight coupling, inconsistent patterns, and technical debt. Implement automated testing, CI/CD, logging, monitoring, security, and performance practices. Own technical workstreams and provide design reviews, code reviews, and mentoring. Participate in client discovery, requirements analysis, demonstrations, deployment, and knowledge transfer.
