Accounting

ai& is a new global AI technology company dedicated to meeting the world's growing demand for AI. Our vision is twofold: to serve as a premier AI lab specializing in localization, and to act as a global infrastructure and compute provider. We are building a unified, optimized global platform that integrates next-generation data centers and infrastructure, heterogeneous compute serving, and advanced model services. We believe that the most effective way to build and scale AI is to own the stack from top to bottom.

At ai&, we empower small teams with the autonomy needed to tackle significant challenges. Our approach is to deconstruct large problems into manageable components and solve complex issues collaboratively. We seek highly motivated, mission-driven individuals who demonstrate strong personal agency. We value curiosity as the foundation of talent, and we are looking for people eager to develop alongside our evolving technology and expanding business.

We are actively hiring worldwide, with presence in Tokyo, SF, Austin, and Toronto. We are more than happy to meet exceptional talent where they are.

As our Accounting hire in Japan, you are the hands doing the work. You will own the day-to-day bookkeeping and transaction processing that keeps ai& Japan's finances clean, accurate, and close-ready every single month. You work directly alongside the Finance Controller — they own the close, you execute it. Every journal entry, every reconciliation, every invoice, every payroll run goes through you.

This is a pure execution role. You are meticulous, fast, and you do not let errors accumulate. You take pride in books that are always in order and a close that never slips because of something on your side. You will also be part of building the accounting infrastructure from scratch — setting up the systems, workflows, and processes that ai& Japan's finance function runs on.
