Member of Technical Staff - Data Scientist

We'relooking for data scientists to help build the next generation of post-training methods for frontier models at Microsoft AI.You'lljoin a small, high-impact team working across all stages of post-training, with a focus onevaluation design, high-quality training data, and scalable data pipelinesforstate-of-the-artfoundation models.

In this role,you'llhelp turn raw model capability intoreliable, aligned, and measurable performance improvements, directly shaping how frontier models behave in real-world deployments.

About the Role:

Microsoft AI is building the next generation of frontier models that power Copilot and other large-scale AI experiences. ThePost-Trainingteamis responsible fortransforming powerful pretrained models intorobust, aligned, and high-performing systemsused by millions of people worldwide.

Our work focuses on improvinggeneral quality, instruction following, coding and math ability, tool use, agentic behaviors, personality, and other critical model capabilities. Weoperateacross the full post-training lifecycle - fromdata generation and curation, toevaluation and diagnostics, toreward modeling and reinforcement learning.

We are a small, highly autonomous team that works closely with pre-training, product, and engineering partners to rapidly iterate on ideas, run large-scale experiments, and safely advance model capabilities. Each team member owns meaningful parts of the post-training pipeline and has direct access to thecompute, data, and decision-making needed to move quickly from insight to production.

Microsoft Superintelligence Team

This role is part of Microsoft AI's Superintelligence Team. The MAIST is astartup-like team inside Microsoft AI, created to push the boundaries of AI towardHumanist Superintelligence-ultra-capable systems thatremaincontrollable, safety-aligned, and anchored to human values.Our mission is to create AI that amplifies human potential while ensuring humanityremainsfirmly in control. We aim to deliver breakthroughs thatbenefitsociety-advancing science, education, and global well-being.

We're also fortunate to partner with incredible productteamsgiving our models the chance to reach billions of users and createimmensepositive impact. Ifyou'rea brilliant, highly-ambitiousand low ego individual,you'llfit right in-come and join us as we work on our next generation of models!
