Senior Full Stack Engineer (Node.js, React) Job - Apply Now

We are looking for a Senior Full Stack Engineer to architect, build, and scale web applications using Node.js, MongoDB, React/Next.js, and Angular. You will lead features from technical design to production support, integrate LLM-powered features alongside AI/ML engineers, and mentor junior and mid-level engineers. You will also present technical decisions and progress to stakeholders, clients, and leadership.

Key Responsibilities

• Architect, build, and scale full-stack web applications using Node.js, Express/NestJS, MongoDB, React/Next.js, and Angular.
• Lead feature development end to end, from technical design and estimation through deployment and production support.
• Design and own RESTful and GraphQL APIs, including Backend-for-Frontend (BFF) layers, and shape API contracts with product and platform teams.
• Build and maintain shared component libraries and design systems (Tailwind, Storybook), and turn Figma designs into pixel-perfect, accessible UI.
• Deploy and operate services on AWS, GCP, or Azure using Docker, Kubernetes, serverless functions, and CI/CD pipelines.
• Integrate LLM-powered features such as AI assistants, semantic search, and RAG pipelines alongside AI/ML engineers.
• Use AI-assisted development tools (Claude Code, Cursor, GitHub Copilot) to speed up delivery while keeping quality high.
• Mentor junior and mid-level engineers through code reviews, pair programming, and technical direction.
• Present technical decisions, trade-offs, and progress clearly to stakeholders, clients, and leadership.
• Take part in on-call rotations and incident response for production systems.

Requirements

• 3 to 6 years of professional software engineering experience, with strong full-stack delivery.
• Expert-level JavaScript and TypeScript, plus strong HTML5, CSS3, and responsive design.
• Production experience with Node.js (Express or NestJS) and MongoDB, with exposure to PostgreSQL or MySQL.
• Strong hands-on experience with React (Next.js preferred) and working proficiency in Angular.
• Solid understanding of system design, microservices, caching (Redis), and message queues (Kafka, RabbitMQ, SQS).
• Hands-on cloud experience (AWS, GCP, or Azure), including containerization with Docker.
• Strong testing habits: unit, integration, and E2E testing with Jest, Playwright, or Cypress.
• Understanding of authentication and security standards: OAuth 2.0, OIDC, JWT, and OWASP best practices.
• Proven ability to lead development efforts, own deliverables, and drive a team toward deadlines.
