Principal Product Manager

Overview The base model gets you capability. Post-training is what turns that capability into a model people actually want to use; one that follows instructions well, has the right tone and judgment for Copilot's surfaces, refuses the right things, and keeps getting better release over release.

We're looking for a Principal Product Manager to sit inside that process. You'll be embedded directly with applied researchers and ML engineers running RLHF, fine-tuning, and preference-tuning pipelines, reading model outputs, calling out what's wrong, and turning that into concrete training priorities. You're the person who brings the end user's voice into a room that's otherwise all metrics and loss curves.

This is a technical, hands-on PM role, not just a roadmap-and-requirements role. You'll spend real time in transcripts and eval dashboards, and you'll need enough grounding in how post-training actually works (RLHF, DPO/preference optimization, instruction tuning, data curation) to have a credible point of view with the research team.

Microsoft’s mission is to empower every person and every organization on the planet to achieve more. As employees we come together with a growth mindset, innovate to empower others, and collaborate to realize our shared goals. Each day we build on our values of respect, integrity, and accountability to create a culture of inclusion where everyone can thrive at work and beyond.

Responsibilities

• Embed in the post-training loop : work day-to-day with research and applied ML teams during fine-tuning and RLHF cycles, reviewing model outputs and giving structured feedback on quality, tone, and behavior
• Define what "good" means for Copilot's models : set the priorities for capability, personality, and safety tradeoffs across surfaces (Microsoft 365 Copilot, Copilot Studio agents, Windows) — where "good" is often genuinely ambiguous and hasn't been decided before
• Run RLHF/preference data campaigns : partner with data and labeling teams to scope what human preference data gets collected, for which behaviors, and why
• Build and maintain behavior evals : translate qualitative judgment calls ("this response felt too hedgy," "this refused when it shouldn't have") into evaluation sets that can be tracked release over release
• Own the feedback loop : turn user research, enterprise customer feedback, and production incident learnings into concrete post-training priorities — closing the gap between "users are unhappy with X" and "the next fine-tune addresses X"
• Make the tuning tradeoffs explicit : helpfulness vs. caution, consistency vs. personality, latency/cost vs. quality — and drive alignment across research, safety, and product leadership on where the line sits
• Represent Responsible AI and enterprise requirements into training priorities — compliance behaviors, refusal policies, and brand voice all have to be reflected in what the model is actually tuned to do.

Required Qualifications

• Bachelor's Degree AND 10+ years experience in product/service/program management or software development
• OR equivalent experience.

Additional or Preferred Qualifications:

• Bachelor's Degree AND 15+ years experience in product/service/program management or software development
• OR equivalent experience.
• 6+ years experience taking a product, feature, or experience to market (e.g., design, addressing product market fit, and launch, internal tool/framework).
• 8+ years experience improving product metrics for a product, feature, or experience in a market (e.g., growing customer base, expanding customer usage, avoiding customer churn).
• 8+ years experience disrupting a market for a product, feature, or experience (e.g., competitive disruption, taking the place of an established competing product).
