Product Designer — Lucky Engine (UI/UX)

Job Description

The Role

Own the UI and UX of Lucky Engine end-to-end. You’ll define how a serious 3D simulation engine looks, feels, and behaves — from the viewport interaction model down to every inspector, panel, and shortcut.

This is not a marketing site, mobile app, or admin dashboard. It is a desktop 3D engine — dense, visual, and powerful, but immediately legible. Software that someone can open for the first time and start working in, and still grow into for years.

The catch: our users are not all 3D experts. They include robotics researchers, ML engineers, hobbyists, startups, and enterprise teams who want to simulate robots and generate training data — many have never opened Blender or Unreal. Your job is to design a tool as powerful as a AAA game engine and approachable enough that someone who has only ever used Cursor or VS Code can be productive in it.

That tension is the design problem.

The existing tools in this category are notoriously painful to use. We are setting a new standard.

What You’ll Design

• Viewport & 3D interaction — camera, gizmos, selection, the “feel” of working in 3D space
• Scene graph and hierarchy — how users build and navigate complex robotic scenes
• Node-based editors — behaviors, materials, data flow, scripting
• Asset editors and content browser — mesh, material, texture, rig, and animation editors; the surfaces where users import, organize, and refine 3D content
• Robot and sensor configuration — joints, kinematics, cameras, lidar, IMU, contact sensors
• Simulation inspection & debugging — playback, scrubbing, state inspection, sensor visualizations
• Timeline and recording — capturing and reviewing training data runs
• Job orchestration — large-scale parallel simulation jobs and datasets
• Training data inspection — reviewing, filtering, and curating engine output
• High-density property panels and inspectors — modular, fast, scriptable
• AI Agent surface — a natural-language interface that lets users describe what they want the engine to do (e.g. “have the G1 robot walk to the table and pick up the cup”) and have the scene set itself up

You’ll work directly with the founders and engineers, set the design direction, and ship.

Design Vision

Lucky Engine should feel like the best of three worlds:

• The density and capability of a AAA game engine — Unreal Engine, Unity, Frostbite, Ubisoft’s Snowdrop, Decima. Modular panels, dockable layouts, deep inspectors, fluid workflows.
• The approachability of modern developer tools — Cursor, VS Code, Linear. Clean typography, sensible defaults, surfaces that don’t punish a first-time user.
