We are seeking an experienced software engineer with expertise in desktop application development (especially Electron/VS Code extensions) to join our IDE team. Unlike traditional web roles, this position focuses on developing and extending a VS Code–based IDE, creating deep integrations with AI, collaborative editing features, and advanced visualizations tailored for semiconductor design workflows.

Core Responsibilities

Design, implement, and maintain VS Code extensions and Electron-based IDE features for the Cognichip platform. Develop advanced IDE features such as AI-assisted coding, linting, cooperative editing, syntax highlighting, and domain-specific visualizations. Integrate the IDE with backend microservices and APIs, ensuring seamless performance across distributed environments.

Build and optimize cross-platform desktop experiences (Windows, macOS, Linux). Collaborate closely with designers to implement polished, intuitive UI/UX patterns inside the IDE. Contribute to performance profiling, debugging, and optimizations to ensure a responsive and reliable user experience.

Required Qualifications ~6+ years of software engineering experience,



with 4+ years in desktop application development (Electron, VS Code extensions, or similar IDE frameworks). ~ Strong proficiency in TypeScript, JavaScript, React, and ES6+. ~ Experience developing VS Code extensions or other plugin-based IDE architectures. ~ Solid understanding of state management (e.g., Redux, Zustand) and component-driven UI frameworks. ~ Knowledge of cross-platform application design (Windows, macOS, Linux). ~ Familiarity with performance profiling and optimization in IDE or desktop applications. ~ Experience with version control and CI/CD workflows (GitHub, Jenkins, etc.).

Preferred Qualifications Exposure to LLMs, AI-driven developer tools, or intelligent assistants inside IDEs. Knowledge of Electron internals and packaging/distribution of desktop applications.

Experience with language parsers, syntax highlighting, lexical analysis, and editor/IDE UX patterns.

Experience implementing authentication, permissions, and role-based access in desktop apps. Familiarity with semiconductor design tools or EDA workflows.

What We Offer Opportunity to shape the Cognichip IDE, a flagship product at the intersection of AI, semiconductor design, and developer productivity. Competitive compensation package including equity. Work alongside world-class engineers, scientists, and product designers. Collaborative and innovative startup culture where your impact is direct and visible.
