AI - Field Application Engineer

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.

Role Overview
As a Field Application Engineer for our AI Platform, you are the technical bridge between ai& and our customers at every stage of the commercial relationship. You will work closely with the sales team in pre-sales engagements, helping customers understand what ai& can do and how it maps to their problems. You will then stay close through onboarding, implementation, and ongoing support, making sure customers are successful on the platform.

This is a role that demands both technical credibility and communication clarity. You need to be technical enough to work with customer engineers, and articulate enough to explain complex AI and inference concepts to a general audience including business leaders, product teams, and executives. You thrive at the intersection of technology and customer problems, understanding what someone needs and figuring out how to get them there.

On the AI platform side, you will work across inference serving, model deployment, custom AI, and agentic workflows. You will represent ai&'s capabilities in the field and bring the customer perspective back into the product and engineering teams.
