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

We are seeking a Software Engineer with deep expertise in functional programming languages, interpreters, and modern web technologies to help shape the future of our next-gen CAD software. In this role, you'll work on KCL, our new programming language for 3D design. You'll help design language features, identify and improve rough edges or hard-to-use features, and improve its interpreter runtime. You'll also integrate KCL into its purpose-built IDE, Zoo Design Studio, allowing users to build KCL programs using a familiar point-and-click GUI. You can get a feeling for KCL in the KCL book. You’ll work across Rust, WebAssembly and TypeScript building advanced developer-centric features. This is a highly collaborative role where you’ll partner with our team to push the boundaries of interactive, code-driven design.

What You’ll Do

Integrate the interpreter for a domain specific language (DSL) with a GUI written in TypeScript

Implement code-mods and other code refactoring tools

Add features and maintain an interpreter written in Rust, running in WebAssembly

Maintain a language parser and syntax highlighting

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. Computer Science or a related field, or equivalent professional experience

Demonstrated professional experience and proficiency in software development contributing to highly scalable and reliable systems

Proficiency with Rust, and Javascript/Typescript

Experience with functional programming languages

Knowledge of language parsers and interpreters

Knowledge of AST driven code-mods

Experience with Git

Solid understanding of modern techniques and algorithms related to workflow design

Familiarity with libraries and tools for programming language interoperability

A testing-based and automation-focused approach to engineering
