Joshua Ellis
Level designer for open-world and multiplayer games.

Hi, I’m Josh, a level designer working in open-world and multiplayer design, most recently at Gunzilla Games.
There I shipped five locations on Off the Grid and pre-produced four more for live service. Before that I spent a year designing Arma 3 missions for a weekly playgroup, and I build my own tools — a voxel level editor, and editor plugins for Unreal.
My life-long love for sandbox games fuels my creativity, and my background makes me care deeply about metrics, production, and improving the working conditions and processes for others on my team.
I’m based in Sheffield, UK, and open to level design roles.

Trinh Nguyen — Senior Level Designer for OTG:
Joshua is a fantastic level designer. I had the pleasure to mentor him at Gunzilla. Joshua is a quick learner and a bright person that is very pipeline orientated. His previous experience allows him to understand project constraints on a more advanced level.
Manuel Escorza — Mid Level Designer for OTG:
I worked with Joshua on several locations during our time at Gunzilla Games. Joshua is a very technically skilled individual that excels at modular workflows and creating pipelines to bring the level and art teams together. He is also a great co-worker and team player capable of adapting to changing requirements and situations inside the project.
