Our client is seeking a Senior Full Stack Developer with a strong emphasis on front-end technologies to join our growing team.

  • Contribute to architectural decisions and advocate for best practices in code quality, testing, and performance.
  • Provide mentorship and technical guidance to junior and mid-level developers.
  • Take ownership of project deliverables and timelines in an agile environment.
  • Participate in code reviews and support CI/CD pipeline improvements.
  • Be an effective communicator who proactively shares knowledge and fosters team collaboration.


Qualifications:

  • 6 years of professional software development experience.
  • Strong proficiency in React and modern JavaScript/TypeScript.
  • Experience working with or migrating from Angular to React is a strong plus.
  • Solid understanding of front-end architecture, component lifecycles, and state management (Redux, Context API, etc.).
  • Exposure to Java on the backend (Spring Boot or similar frameworks preferred).
  • Comfortable working across the full stack and integrating with APIs and backend services.
  • Proven track record of leading by example and mentoring peers.
  • Excellent verbal and written communication skills.
