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

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
