Lead 3D / Engine Engineer (Unity, C#, shaders, WebGPU) with an AI deployment role, game studio, Tokyo (remote)

Location requirement

You must already be living in Japan with valid work authorization. We are not sponsoring relocation or visa transfers from overseas for this role. Applications from outside Japan will not be considered.

The context

Our client is a game studio in Tokyo, part of an international group, working on co-development, console and mobile ports and live operations for well-known publishers. They want a senior engineer who can go deep on 3D and engine work, and who can also help the studio change the way it produces games with AI.

The role is still being shaped, and the person who joins will have a real say in what it becomes.

What you'll do

• Own 3D and engine topics on the studio's game projects: Unity and C#, rendering, performance
• Write and optimise shaders (HLSL, GLSL, compute) and work on WebGPU where it fits
• Look at how the teams actually produce games, and find where AI can save time or open new options
• Pick, build and roll out the right AI tools on real projects, then make sure people use them
• Share what works with the other teams, and drop what doesn't

What we're looking for

• Currently based in Japan with valid work authorization, no relocation or visa sponsorship from overseas for this role
• Around 10 years of hands-on Unity and C#, with lead experience on shipped games
• Solid shader work (HLSL, GLSL, compute). WebGPU, Gaussian splatting or other recent rendering techniques are a plus
• Real curiosity for AI applied to production pipelines, with things you have actually built or tried
• Professional Japanese is a strong plus, English is useful

Terms

• Permanent contract with Abbeal Japan, or freelance
• Tokyo, remote within Japan
• Compensation depending on profile, to be discussed
• Start as soon as possible
