Software Development Engineer

Staff Software Engineer – Developer Tooling

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.

• 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.

• 6+ years of software engineering experience, with 4+ years in desktop application development (Electron, VS Code extensions, or similar IDE frameworks).
• Strong proficiency in Type Script, 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 (Git Hub, Jenkins, etc.).

• 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.

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.
