At LG, we are looking for teammate to make continuous improvement to wide variety of tools (maily VSCode extensions) to support our in-house product developers.

Take ownership of the static analysis and language server tool (VS Code extension), focusing on maintenance and continuous improvements.

Optional: Extend ownership to other VS Code extension–related tooling like the debugger. The debugger supports mixed-mode debugging (Script + C/C++), enabling software validation on Linux without physical hardware by integrating with a local C-based simulation

 

*** Responsibilities

• VS Code Extension (TypeScript): Maintain and optimize extension logic (activation events, command registration, configuration), improving stability and performance.
• Static Analyzer Tool: Support and enhance static analyzer tool (adhering to Language Server Protocol) for our proprietary DSL script (auto-completion, diagnostics, navigation, syntax support).
• Debugger Engine (DAP): Maintain and extend the Debug Adapter Protocol (DAP) implementation to ensure stable mixed-mode debugging, coordinating execution between the script interpreter and the native C simulation engine.
• Codebase Modernization: Refactor legacy TypeScript modules, improve performance of data-heavy logic, and reduce technical debt (readability, testability, maintainability).
