Job description

  • We are seeking an experienced UI-primary Full Stack Developer with deep front-end engineering expertise. JavaScript is the top required skill. You will build modern, responsive web experiences and collaborate closely with backend and platform teams. Java server-side experience is highly desirable to support end-to-end delivery, API integration, and full lifecycle ownership., * Design, develop, and maintain responsive, accessible, and performant user interfaces using JavaScript (ES6+), HTML5, and CSS3.
  • Build reusable UI components and patterns; enforce UI standards and best practices.
  • Develop with modern UI frameworks such as React or Angular; apply responsive web design concepts.
  • Integrate front-end applications with backend services via REST APIs; collaborate on API contracts and data models.
  • Highly desirable: contribute to backend development using Java and Spring (e.g., Spring Boot) to develop and maintain RESTful services.
  • Implement and enhance CI/CD pipelines; automate builds, tests, and deployments; support application-side DevOps practices.
  • Write clean, well-documented code and participate in code reviews to ensure quality and maintainability.
  • Troubleshoot production issues across the stack; collaborate with cross-functional teams (QA, DevOps, Security) to resolve incidents.
  • Work in Agile/Scrum teams; participate in sprint planning, grooming, demos, and retrospectives.

Requirements

  • JavaScript (ES6+) - advanced proficiency; strong understanding of asynchronous programming, performance, and debugging.
  • Front-end engineering with HTML5 and CSS3; strong grasp of responsive web design and cross-browser compatibility.
  • React or Angular - hands-on experience building enterprise web applications.
  • Strong foundation in software engineering best practices: coding standards, code reviews, source control, build processes, testing, and operations.
  • Git-based collaboration workflows (branching, pull requests, code reviews).

Highly Desirable Skills

  • Java (preferably modern versions) with strong OOP and design principles.
  • Spring Boot / Spring MVC for building RESTful services; microservices exposure.
  • Database skills: SQL and relational database experience; ORM knowledge (JPA/Hibernate) preferred.
  • Security concepts: authentication/authorization; OAuth2/JWT familiarity is a plus.

Additional Skills (Preferred / Nice-to-Have)

  • TypeScript and modern front-end tooling (Node.js, NPM/Yarn, Webpack/Vite, ESLint/Prettier).
  • UI testing: Jest and component testing; end-to-end testing tools such as Cypress or Playwright.
  • API testing and validation tools (e.g., Postman).
  • CI/CD tools (Jenkins, GitHub Actions, GitLab CI) and pipeline automation.
  • Containerization and orchestration: Docker and Kubernetes.
  • Cloud exposure: AWS or Azure deployment experience.
  • Observability and production support: logging/monitoring tools (e.g., Splunk/ELK, Prometheus/Grafana); incident triage and troubleshooting.
