Job requirements
-What will your day to day be like?-
You will:
Partner
with product managers, merchandisers, UX researchers, and analysts to shape
hypotheses at intake




— coaching toward better-formed questions rather than gating on incomplete requests.
Own the
experimentation roadmap
for assigned eCommerce surfaces; arbitrate prioritization across stakeholders against shared business objectives.
Design
experiments
using methodology, including overall evaluation criteria selection, holdback structure, sample-ratio integrity, and interaction-effect awareness for high-impact tests.
Manage the
experimentation lifecycle end-to-end
: intake clarification, development partnership with engineering, QA coordination, launch, monitoring, analysis, and results communication.
Adapt
patterns
from cross-stack and cross-regional experimentation work to local stakeholder context; contribute new patterns back to the shared library when locally-discovered insights generalize.
Partner
with regional receiving teams on the experimentation guardrails that let those teams operate independently with confidence.
Communicate
results
in language calibrated to operational, tactical, and executive audiences: winners that ship, learnings from non-winners, and decision-relevant signal across the full test corpus.
Maintain the experimentation
registry
: hypothesis, design, audience, guardrails, results, and decision attribution.
-What are we looking for?-
5–7 years




of program management or product management experience, with at least
3 years owning experimentation
or
A/B testing
programs at scale on consumer-facing digital properties;
eCommerce
strongly preferred.
Demonstrated comfort with
experimentation
methodology
including overall evaluation criteria, holdback discipline, sample-ratio mismatch detection, interaction effects, and the difference between practical and statistical significance.
Strong stakeholder partnership
skills
across product management, merchandising, UX research, analytics, and engineering — including experience arbitrating competing priorities against shared business objectives.
Comfort presenting
evidence
that
disconfirms
leadership or stakeholder hypotheses and translating non-winning tests into decision-relevant learning.
Track record of regional or general
program coordination
, including coordination across multiple eCommerce stacks or business units.
Excellent
written and verbal communication
; able to calibrate from operational detail to executive narrative without losing rigor at either altitude.
Hands-on experience
with a mature experimentation platform (Dynamic Yield strongly preferred; Optimizely, Adobe Target, or VWO acceptable).
Web analytics
experience required — Adobe Analytics strongly preferred; Google Analytics acceptable.
Proficiency with
JIRA
and Confluence.
BA/BS in a quantitatively-oriented discipline (mathematics, statistics, economics, computer science, business analytics, or similar) preferred. Equivalent demonstrated experience considered.
Nice to have:
Experience operating in a
Center of Excellence
