Senior Software Engineer, Frontend

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.

• 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

• 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

• A background in geometry and/or experience with design-based software
