Lucky Robots Engineer Challenge
Unreal Gameplay Engineering Challenge
We’re Lucky Robots—building Unreal Engine simulations to train robots with synthetic data. It’s fast, realistic, and meant to actually work in the real world. We are a fully remote team of superstar engineers, hiring new grads with deep Unreal knowledge, who are excited to build the future of robotics with us.
We’re hiring talented new grad game developers for a full-time, fully remote role. We usually work around Central Time hours to stay in sync as a team, but there is flexibility. New grads will be onboarded with support from senior engineers. No US visa sponsorship/support at this time.
We’d like to see how you approach gameplay engineering and physics in Unreal. Please complete the following small challenge and submit a short video walkthrough (max 5 minutes). Spend no more than a couple hours on it.
Challenge
Build a small Unreal Engine prototype that shows off an interactive physics-based gameplay mechanic.
Your prototype should:
Use Unreal Engine’s built-in physics (Chaos) — optional bonus if you experiment with an external backend like MuJoCo.
Include at least one core gameplay mechanic (examples: pushing/pulling objects, stacking, triggering a chain reaction, solving a simple puzzle, ragdoll interactions, or AI reacting to physics).
Add one unique twist of your own to show creativity.
Deliverables
A packaged build (or video capture of it running).
A ≤5-minute walkthrough video where you:
Demonstrate the mechanic in action.
Explain briefly how you implemented it (Blueprints vs C++, physics setup, any custom code).
Share why you chose this approach.
Evaluation
We’re looking for:
Unreal fluency – how you set up and organize your project.
Physics + gameplay understanding – correct, creative use of collisions, forces, constraints, etc.
Code/design clarity – can you explain your thought process clearly?
Creativity & polish – does it feel like something beyond a tutorial?
