Job Summary

Overview

CADET (Customer and Analytics Driven Evals Team) is building a customer-grounded quality system for Copilot. Our mission is to rapidly identify the customer scenarios that matter most represent them faithfully in evaluation and learning assets run quality gates continuously and turn every important failure into reusable product and model improvements. We bring together DSAT and other product signals deep customer engagements to create representative eval sets. Operating in a fast-paced environment we connect customer grounded quality issues with quality teams to advance Copilot quality and product innovation.

We are looking for a Senior Data Scientist to build the measurement and decision system that determines where CADET invests and whether Copilot is improving for the customers and intents that matter most. You will combine DSAT usage customer engagement product feedback evaluation and other quality signals to create a representation- and coverage-aware view of customer quality. You will define the taxonomies metrics prioritization models analyses and reporting mechanisms that turn a fragmented signal landscape into clear decisions. You will synthesize quality opportunities investigate loss patterns shape evaluation portfolios and ensure recurring quality gates reflect real customer experiences rather than static benchmarks.

Microsofts 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

Build and operate a data-driven prioritization framework for CADET quality forums and partner teams that combines DSAT customer impact usage severity strategic importance representation and current evaluation coverage to guide quality investments.
Define and maintain intent sub-intent customer scenario coverage and loss-pattern taxonomies that can be used consistently across signal intake triage evaluation and reporting.
Measure how well evaluation portfolios represent production traffic customer segments workflow complexity locales grounding paths and material failure modes.
Identify underrepresented customers intents scenarios and loss patterns and translate those gaps into evaluation and data-collection priorities.
Design quality gates for top intents and top customers including success thresholds segmentation run cadence escalation criteria and reporting.
Build recurring scorecards that connect offline evaluation movement with online measures such as DSAT task completion retries abandonment and escalation; detect meaningful quality changes; and alert accountable owners when action is required.
Analyze offline-online agreement evaluation freshness regression coverage grader reliability and quality movement over time.
Develop sampling weighting deduplication clustering and trend-detection approaches for noisy customer and product signals using resource- and performance-optimized data-analysis solutions that make effective use of CPU GPU and platform capacity.
Use causal and experimental methods where appropriate to distinguish correlation attribution and treatment impact and translate the findings into concrete product model data and evaluation investment decisions.
Partner to translate customer evidence into valid task distributions datasets metrics and reward signals and to encode metrics taxonomies data-quality checks and reporting into automated pipelines.
Leverage team signals from customer engagements to understand workflows business impact expected outcomes and gaps hidden by aggregate metrics; produce clear recommendations for product model data and evaluation investments; and communicate them to senior leaders.
Establish solid practices for data provenance privacy responsible use reproducibility and metric governance.
