Applied AI Engineer - Tokyo

About the Position

Applied AI Engineer - Tokyo

OpenAI’s Applied AI Engineering team helps organizations turn frontier AI capabilities into safe, reliable, and high-impact production systems. We work with customer executives, product and engineering teams, security leaders, and transformation teams to identify valuable opportunities, accelerate technical implementation, and scale what works. Enterprise deployments are defined by complexity rather than any one industry: existing architectures, diverse data environments, security and governance requirements, multiple stakeholder groups, and organization-wide change. We turn lessons from these deployments into better products and reusable patterns for customers everywhere.

Responsibilities

As an Applied AI Engineer, you will:

• Partner directly with enterprise customers to identify high-value opportunities and translate them into technical architectures, implementation plans, evaluation strategies, and measurable success criteria.
• Design, build, and deploy AI systems that solve important customer problems and produce measurable business outcomes.
• Work hands-on in code to build prototypes, evaluation harnesses, reference implementations, integrations, and production accelerators.
• Make sound technical decisions across models, agents, retrieval, tools, data, reliability, observability, latency, cost, safety, security, and governance.
• Diagnose complex implementation challenges, reproduce failures, test hypotheses, and drive blockers toward resolution.
• Help customers progress from promising prototypes to reliable production systems, sustained adoption, and scaled impact.
• Partner closely with customer engineering teams and OpenAI Product, Research, Engineering, Security, and go-to-market teams, translating deployment experience into high-signal product feedback.
• Create reusable architectures, tooling, playbooks, and technical guidance that accelerate future enterprise deployments.

Requirements

• Demonstrated track record of designing, building, and delivering AI or machine-learning systems in enterprise environments, including taking systems from prototype to production.
• Proficiency in Python and comfortable working across an AI application stack; experience with JavaScript, TypeScript, or another relevant language is valuable.
• Understanding of how to evaluate AI systems systematically using representative data, graders, production signals, and human judgment.
• Experience navigating enterprise production requirements such as integrations, reliability, observability, security, privacy, data governance, performance, and cost.
• Ability to connect technical decisions to customer workflows, adoption, and measurable business outcomes.
• Fluency in Japanese and English.

We Offer

• Opportunity to work on consequential real-world deployments at the frontier of AI.
• Hybrid work model with 3 days in the office per week.
• Relocation assistance for new employees.
