Grow faster than your job title. Work across teams, impact millions, and join a culture where competence, ownership, and output beat hierarchy, age, and titles.
We usually respond within a day
We build ambitious, high-quality mobile game(THE Game) with a small team that moves fast, cares deeply about the player experience, and knows that "it worked in the Editor" is not a production strategy. On-site in Tokyo, Japan.
You'll be a senior individual contributor who owns real gameplay and client systems end-to-end: design, build, ship, debug, and keep improving after launch. You like hard problems, you have sharp judgment, you read a brief closely enough to work efficiently and unblock yourself, and you want the trust and independence to do some of the best work of your career. "Stay a while, and listen!" If you're reading carefully, put this phrase somewhere in your application.
What you'll own
Robust Unity and C# gameplay, UI, and client systems for a live mobile game.
Modular, data-driven features that respond safely to remote config, live content, and backend state.
Features from ambiguous idea to polished, shipped, and monitored reality.
The gnarly production bugs, including the one that only happens on one Android model, in landscape, after returning from sleep.
What you need(qualificatoin)
8+ years in game development, 5+ of them with Unity and C#.
Shipped multiple games, at least one in Unity.
Deep Unity knowledge: lifecycle, MonoBehaviours, ScriptableObjects, prefabs, Addressables, serialization, and content loading.
Strong C# fundamentals: async, cancellation and cleanup, memory and performance awareness, maintainable architecture.
Experience with live service or data-driven systems (remote config, events, backend-driven behavior).
Sharp mobile debugging instincts, and the autonomy to own complex work while communicating clearly with the whole team.
Fluent English.
Nice to have
Japanese language ability.
Free-to-play experience.
CI/CD familiarity.
A healthy respect for null, asset bundles, and the difference between Awake, Start, and "why is this running before that?"
