Staff Software Engineer – Developer Tooling

Staff Software Engineer – Developer Tooling & IDE Platforms

Toronto, ON | Full-Time | On-Site

The Opportunity

We are building a new class of desktop-first developer tooling designed for highly technical engineers working on complex, computation-heavy workflows. The product centers on an extensible IDE environment that blends local desktop performance with cloud-backed services, advanced visualization, and AI-assisted workflows.

This role is not a traditional web application position. You will be working deep inside a VS Code–derived IDE and Electron-based desktop environment, designing and implementing core tooling that engineers use for authoring, collaboration, analysis, and simulation-driven development.

What You’ll Do

• Architect, build, and evolve extensions and core features within a VS Code-based IDE and Electron desktop application
• Develop advanced editor capabilities such as intelligent code assistance, linting, collaboration features, domain-specific visualizations, and custom language tooling
• Integrate desktop tooling with distributed backend services and APIs to support complex workflows
• Deliver polished, high-performance cross-platform experiences across macOS, Windows, and Linux
• Partner closely with product and design to implement intuitive, professional-grade UI patterns inside a developer tooling environment
• Profile, debug, and optimize performance to ensure responsiveness at scale
