Full Stack Engineer (Node.js + React.js) - In-Sprint Automation Focus

GSSTech Group

You will be responsible for embedding test automation within the development lifecycle, ensuring every feature is production-ready with immediate validation. The goal is to eliminate testing bottlenecks, reduce regression risk, and maintain high delivery velocity.

Key Responsibilities

• Design, develop, and maintain scalable web applications using React.js (TypeScript) and Node.js
• Build automated test scripts in parallel with feature development (in-sprint automation)
• Ensure high code quality through unit, integration, and end-to-end testing
• Collaborate closely with product, QA, and DevOps to ensure seamless delivery
• Integrate automated tests into CI/CD pipelines for continuous validation
• Identify performance bottlenecks and optimise both frontend and backend systems
• Contribute to architecture decisions, focusing on testability and scalability
• Reduce dependency on post-development QA cycles by shifting quality left

Core Technical Skills

Full Stack Development

• Strong experience in React.js (TypeScript), JavaScript, HTML5, CSS (SASS / Tailwind / CSS-in-JS)
• Solid backend development experience with Node.js and RESTful APIs
• Experience with NoSQL databases (MongoDB preferred)
• Understanding of GraphQL (nice to have)

Automation & Testing (Critical Requirement)

• Hands-on experience with test automation frameworks (e.g., Playwright, Cypress, Jest)
• Ability to write testable, modular code with high coverage
• Experience implementing in-sprint or shift-left testing practices
• Strong understanding of unit, integration, and E2E testing strategies

DevOps & Architecture

• Experience with CI/CD pipelines
• Knowledge of Docker, Kubernetes, and distributed systems
• Familiarity with API gateways and authentication mechanisms (JWT, OAuth, SSO)
• Exposure to event-driven systems / message queues (Kafka, etc.)

Functional & Domain Experience

• Experience working in Agile/Scrum environments
• Banking or Retail domain experience is a plus
• Strong focus on code quality, security, and performance optimisation

What We re Really Looking For

• A developer who doesn t throw code over the wall to QA
• Someone who owns quality, not just delivery
• Engineers who can balance speed with stability
• People who understand that untested code is incomplete code

Experience

• 5+ years in full stack development (React + Node.js)
• Proven experience in automation within development cycles
