Pfizer US Commercial is scaling a portfolio of AI initiatives, each launched as an experiment measured against a real-world baseline. The value of that portfolio depends on one thing: a shared, credible definition of what valuable looks like plus the evidence to prove we are reaching it.

We are hiring a Director of Experimentation & Measurement to own that definition end to end. This is not a scorekeeping role. You will decide what is worth proving next, design the experiment that proves it, set the bar for success before the work begins, and tell the story of what the evidence means to the people making the biggest decisions. You are equal parts systems thinker, experiment designer, and storyteller, with the rigor to make sure the story is true.

This is a build-from-scratch role for someone who can see across a whole portfolio, frame the questions that matter most, and hold the independence to say when a result does not clear the bar.

What You Will Own
- Success criteria & proof standards. Own the portfolio-wide standard for what counts as proof—defined before work begins,



not after results land. Draft and socialize pre-registered success criteria for each initiative (primary KPIs, guardrails, minimum detectable effect, read windows). Maintain a shared measurement playbook (matched controls, power calculations, blinded review, backtesting where appropriate).
- Portfolio learning agenda. Prioritize what the portfolio must prove next—and in what sequence evidence compounds. Maintain a ranked learning agenda across initiatives and recommend the next proof point per initiative.
- Experiment design & statistical rigor. Review experiment designs: control arms, audience matching, read windows, confounders, data leakage risks. Run power analysis and flag underpowered or ungradeable designs before launch.
- Evidence narrative for senior leaders. Produce evidence read memos on a fixed cadence: what was tested, what was observed, what it means, what is recommended. Synthesize
