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.

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
