Senior Data Scientist - Media Optimization
Microsoft
We’re building a Frontier Marketing organization where the Media Data Science & Analytics team leads the way in transforming how Microsoft measures, analyzes, and optimizes media investments. Our team blends advanced analytics, experimentation, and AI-powered insights to drive smarter decision-making and measurable business outcomes across paid media and owned digital properties. We operate with agility, prioritize outcomes over activity, and embrace rapid learning loops to unlock deeper audience understanding, maximize campaign impact, and accelerate innovation in media strategy.
To support this transformation, we are seeking a Senior Data Scientist to help us measure the incremental impact of advertising spend and use that to help our media planning partners optimize media campaigns. Marketing data science is inherently challenging: data is often observational, incomplete, biased, or limited in scale, and outcomes unfold over time across complex systems. The successful candidate will be someone who can apply rigorous causal methods, exercise sound statistical judgment, and translate uncertainty into actionable insights that inform high-stake investment decisions.
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.
In alignment with our Microsoft values, we are committed to cultivating an inclusive work environment for all employees to positively impact our culture every day.
Responsibilities
Causal Measurement & Business Impact
Design and apply causal inference approaches (e.g., quasiexperimental methods, incrementality testing, observational analysis) to estimate the true impact of media investments in settings where randomized experiments may be limited or infeasible.
Evaluate effectiveness of marketing strategies while explicitly accounting for data limitations, confounding, selection bias, and uncertainty.
Translate complex causal findings into clear, decision-oriented narratives for senior marketing and business stakeholders.
Modeling, Statistics & Analysis
Apply advanced statistical techniques and machine learning where appropriate, with a bias toward interpretability and causal validity over purely predictive performance.
Balance methodological rigor with pragmatism, selecting approaches that are fit for purpose given the data and business context.
Write high quality analytical code (Python, SQL) to support reproducible research, exploratory analysis, and ongoing measurement efforts.
Identify opportunities to improve measurement approaches, challenge existing assumptions, and introduce best practices grounded in both academic research and industry experience.
Data Understanding & Stewardship
Prepare, validate, and analyze complex marketing datasets, identifying data quality issues, structural changes, and limitations that materially affect inference.
Communicate data risks, constraints, and implications proactively to senior partners, ensuring conclusions are appropriately scoped and caveated.
Uphold high standards for data ethics, privacy, and responsible use, with careful attention to how data is collected, modeled, and interpreted.
What Success Looks Like
Media investment decisions are better informed by clear, credible causal insights rather than surface level correlations.
Stakeholders understand not only what the data suggests, but how confident we are and why.
Analytical recommendations appropriately reflect data constraints and uncertainty, earning trust through transparency and rigor.
