About The Role

As a Senior Frontend Engineer at Zoo, you'll play a crucial role in the development and enhancement of our novel open-source CAD modeling app, Zoo Design Studio. This unique, DSL-driven application leverages traditional CAD UI for code generation/editing while streaming a 3D scene from our remote graphics engine. This is a "back of the front-end" role, where your efforts will be instrumental in creating and gluing features together from our UI that drives DSL code-mods, triggering executions with our Rust/Wasm DSL, or interfacing with our backend's WebSocket API and doing so in an extensible way. We're looking for a seasoned Engineer with substantial experience building highly performant, scalable web applications with a deep understanding of performance optimization techniques. This is an awesome opportunity to significantly impact one of our core products during this critical phase of growth for our team.
What You'll Do

• Develop and optimize the frontend of our modeling app, focusing on performance and user experience
• Collaborate with backend teams to design and implement robust APIs that support the app's code-driven design functionality
• Enhance the app's UI/UX by leveraging Typescript, React, and XState, ensuring that the interface is both powerful and easy to use
• Develop delightful CodeMirror extensions that bridge the gap between the user's code and the 3d-model
• Implement advanced AST/code-mods, CodeMirror enhancements, and deep integration with WebAssembly (Wasm) for performance improvements
• Utilize Xstate for state management to maintain app consistency and reliability across various user interactions
• Apply a deep understanding of JavaScript and browser internals to improve app functionality and performance

What You'll Need

• B.S. in Computer Science or a related field, or equivalent professional experience
• Substantial experience in frontend software development building complex, highly performant and scalable applications
• Strong proficiency in Typescript and React, with a portfolio or examples of complex applications built using these technologies
• Deep knowledge of JavaScript and its internal workings and performance optimization techniques
• Familiarity with WebAssembly (Wasm) and its use in web applications for performance enhancements
• Understanding of browser internals across major browsers (Chrome, Firefox, Chromium, Brave, etc.) and their impact on application performance and compatibility
• Knowledge of Xstate or similar state management libraries

Nice to Have

• Proficiency with Rust
• Experience with CodeMirror6
• Experience with ASTs even if custom ESLint rules
• Experience with WebGL or web graphics
• A background in geometry and/or experience with design-based software
