About The Position

Motif is building an agent-native platform for designing and building buildings. The Modeling team owns the modeling experience end to end, including the UI, data model, and algorithms behind building models. The team connects an intuitive interface to a robust data model and fast algorithms to make user actions reliable, high-performance 3D modeling operations, while building features as an extensible platform. Motif is seeking an experienced 3D application developer to build cutting-edge, high-performance web applications. The role uses 3D modeling expertise and full-stack development experience to build robust software with modern languages and technologies such as Rust and WebAssembly (WASM), and calls for a thoughtful approach to using AI tools in day-to-day work.

Requirements

  • Understanding of the 3D modeling domain as applied to architecture, mechanical design, game development, or an adjacent field.
  • At least 5 years of experience developing complex, production-quality software products.
  • Production-level Rust or other object-oriented development experience, with a strong understanding of memory management, concurrency, and performance optimization.
  • Proficiency in at least one additional language, such as JavaScript or TypeScript, for contributing across the stack.
  • Experience building web applications.
  • Experience using AI-assisted development tools in real production work.
  • Excellent problem-solving, communication, and collaboration skills.

Nice To Haves

  • Understanding of design-by-composition and its applications in Rust.
  • Experience with WebAssembly in a browser context, including compiling Rust to WASM and integrating WASM modules into a JavaScript/TypeScript application.
  • Experience building and maintaining complex, high-performance distributed systems.

Responsibilities

  • Design, develop, and maintain high-performance applications in Rust, leveraging its safety, concurrency, and performance capabilities.
  • Contribute across the stack as needed, including React, TypeScript, and WebAssembly.
  • Partner with product managers and user experience designers to clarify requirements and translate them into software features.
  • Maintain necessary automated test coverage by implementing unit and integration tests.
