GSSTech Group

About the Role
We're hiring an engineer who can build scalable backend services, own automated test coverage end-to-end, and use AI-assisted development tools to move faster without cutting corners.

What You'll Do

  • Design, build, and maintain backend services using Node.js and Express
  • Write and maintain robust automated test suites across API, UI, and integration layers
  • Work with both SQL and NoSQL databases (PostgreSQL, MongoDB) to support application needs
  • Use Git for version control and JIRA for issue tracking as part of daily workflow
  • Leverage AI-assisted development tools, specifically Claude Code, to accelerate delivery and improve code quality

What You'll Need

  • Strong proficiency in JavaScript and TypeScript
  • Solid, hands-on experience with Node.js and Express
  • Practical experience with automated testing tools such as Playwright, Cypress, Selenium, or Rest-Assured
  • Working knowledge of SQL and NoSQL databases
  • Proficiency with Git and JIRA
  • Hands-on experience using AI-assisted development tools (Claude Code preferred)
