3 days ago

Redwood City, California, United States Cognichip Full time $200,000 - $250,000 per year

At Cognichip, we are building the next-generation IDE to empower semiconductor design engineers with a 10x productivity boost through AI-native workflows and seamless integration with high-performance simulation engines.

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, collaborative 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.
