Frontend Developer

Resource Modeling Solutions is seeking a creative and driven Frontend Developer to join our distributed team. This role is ideal for someone who loves crafting fast, elegant, and reliable user experiences; specializing in making complex data feel intuitive and actionable. You will help design, implement, and refine the front-end of AMP, our visualization and analytics platform for mining and mineral resource estimation.

You'll work in a modern React 19 + TypeScript codebase (with the React Compiler enabled) built on the TanStack suite (Query, Router, Form, Virtual), Zustand, Zod, Headless UI, Tailwind CSS, and dnd-kit, backed by a fully typed GraphQL API (Hasura + GraphQL Code Generator). Beyond standard app UI, AMP includes interactive 3D visualization of geologic models (vtk.js/WebGL), charting, embedded code editors, Jupyter notebook integration, and real-time collaboration, so there's plenty of room to go deep on performance and data-heavy interfaces.

This position blends collaborative and independent work, and it's a great fit for strong communicators who are self-motivated and comfortable in a remote, distributed environment.
