Job Description

Overview

Microsoft Copilot is evolving from a chat interface into an intelligent, agentic system that understands context, adapts to users, and communicates intent and reasoning in trustworthy ways. Identity & Expression defines how Copilot shows up to users - its presence, tone, timing, and behavior -across consumer and enterprise experiences.

As the Principal Product Manager for Copilot Identity, Expression & AI Companions, you will own Copilot’s expression and embodiment layer, with Mico as a core reference implementation. Based in Japan, this role serves as the product owner for how expressive AI agents are designed, evaluated, and deployed globally, using Japan as a lead design and enterprise pilot market.

Copilot being Microsoft core AI product bet. This role requires an AI-native mindset, strong enterprise judgment, and the ability to make product decisions under AI uncertainty - especially around trust, tone, restraint, and evaluation.

※ すべての条件を完全に満たしていなくても、本ポジションに強い関心がある方はぜひご応募ください。

Responsibilities

Define Copilot’s Identity & Expression strategy across text, voice, and UI-aware surfaces, including how AI agents express reasoning, confidence, uncertainty, and progress.

Own Mico as the reference implementation of Copilot Identity & Expression, ensuring it evolves as a platform capability rather than a standalone feature.

Translate expressive and agentic AI capabilities into clear enterprise value, such as onboarding, workflow guidance, and reduced cognitive load.

Define enterprise trust models for expressive AI, including governance, admin control, safety constraints, and predictable failure modes.

Lead AI evaluation strategy for expressive and agentic experiences, defining quality bars beyond accuracy: trust, tone, appropriateness, and user confidence.

Use Japan as a strategic design and enterprise pilot market, incorporating cultural sensitivity, politeness, and indirect guidance into global Copilot standards.

Partner closely with engineering, design, research, security, legal, and go-to-market teams across Japan, the US, and China to deliver aligned Copilot experiences.

Communicate product vision and trade-offs clearly to executive stakeholders, representing Identity & Expression as a core Copilot system.

Qualifications

Required Qualifications (Must Have)

7+ years of software product management taking from a user need, a prototype from engineering to market.

Hands-on experience delivering AI or generative-AI-powered features or products.

Experience working on enterprise or business-facing products, including IT, security, or operational constraints.

Experience evaluating product quality using both quantitative metrics and qualitative feedback, including cases where release decisions were adjusted or delayed.

Proven experience working cross-functionally with engineering, design, research, and business stakeholders.

Nice to Have

Experience with AI agents, Copilot-style assistants, or conversational interfaces.

Enterprise productivity, collaboration, or workflow automation background.

Experience working with global teams across Japan and other regions.

Business-level or fluent Japanese language proficiency.

Why This Role Matters

This role defines how Copilot earns trust through expression, presence, and restraint. As AI systems become more capable, how they communicate becomes as important as what they do. You will shape a core Copilot capability that affects millions of users and enterprise customers globally.
