About Us
Zoo is building the next generation of hardware design tools redefining how hardware products are designed, developed, and built. Our platform combines a modern, cloud-native CAD environment with AI-powered engineering workflows, helping teams design, iterate, and manufacture products faster than ever before. We are headquartered in Los Angeles, CA with both a local and remote team. We were founded and incubated by Embedded Ventures in 2021.
About You
We’re looking for curious, innovative, and ambitious self-starters to join our growing team to help us bring our mission to life. We think you’ll thrive on our team if you’re:
- Curious at your core, with an eagerness to learn and do things differently
- Customer-focused, always thinking about ways to improve the user experience
- Able to operate autonomously and work asynchronously, while also being an effective team player
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
