• Contribute to the architecture of a modular and extensible IDE platform
• Enable integration with modern AI-assisted development tools
• Implement features supporting code analysis, code navigation, code completion and other developer productivity capabilities
• Improve the overall developer experience for SmarTest test program development
• Analyze and resolve technical issues across the VS Code/LSP platform
• Develop automated tests and contribute to platform quality and stability
• Collaborate with development teams in Germany, India, China and other international locations
• Coordinate technical interfaces and requirements with other SmarTest development teams
• Continuously evaluate new technologies and developments in the VS Code and AI developer-tooling ecosystem

What You Will Work On
You will help establish and evolve a strategic development platform for future SmarTest development. The goal is to enable customers to use modern IDE technologies and the rapidly growing AI ecosystem around VS Code while maintaining seamless integration with SmarTest.
