Job description

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

What We’re Looking For

6+ years of professional software engineering experience, including meaningful time building desktop or IDE-style applications

Hands-on experience with Electron, VS Code extensions, or comparable plugin-based editor platforms

Strong command of TypeScript, modern JavaScript (ES6+), and component-driven UI development (React or similar)

Solid understanding of application state management and complex UI architecture

Experience designing for cross-platform desktop environments

Familiarity with performance optimization, debugging, and tooling for large applications

Comfort working with Git-based workflows and modern CI / CD pipelines

Nice to Have

Experience building AI-assisted developer tools or working with LLM-powered workflows

Knowledge of editor internals, language tooling, syntax systems, or parsing

Exposure to desktop application packaging, distribution, and update mechanisms

Experience implementing authentication, permissions, or access control in desktop software

Familiarity with highly technical engineering domains or specialized design workflows
