Position Summary...

What you'll do...

Lead the centralization of testing and measurement at Sam’s Club by building a single experimentation and measurement platform and launching self-service tools that empower associates to run high-quality experiments independently. Starting with in-club measurement and moving to Omni you’ll establish scientific standards, governance, and guardrails that make results trustworthy and repeatable. You will translate complex data into clear, actionable decisions, mentor a high-performing team, and partner across Product, Engineering, and the business to drive measurable business impact—while reserving your team’s deep expertise for the most complex use cases.

What** **You’ll** **Do (Performance Objectives)

+ **Lead** **testing & measurement** **framework** Inventory current experimentation practices across teams; map data sources, metrics, and decision paths; and publish a **Unified Testing & Measurement Playbook** (taxonomy, KPI catalog, experiment types, power/MDE guidance, guardrails, and approval paths). Secure cross-functional alignment.

+ **Design the experimentation platform** Define architecture and build-versus-buy strategy for an enterprise testing **platform** (assignment service, telemetry, experiment registry, metrics pipeline, results service, observability, and audit trails). Kick off MVP build with cross functional partners; integrate with access control, and data platforms.

+ **Launch self-serve experimentation (4–6 months):** Ship a guided, **self-service tool** enabling ~80% of standard experiments without DS support (A/A checks, sizing calculators, pre-registration, guardrails, and standardized readouts). Train product/ops partners and stand up community of practice. **Success looks like:** ≥70% of experiments initiated via self-serve; median time to test start reduced by ≥40%.

+ **Deliver in-club measurement excellence (pilot → scale):** Stand up robust **in-club measurement** for prioritized initiatives (e.g., signage, layouts, checkout prompts, labor/process changes) using appropriate designs (RCTs, matched controls, diff-in-diff, synthetic control). Publish weekly readouts and executive rollups.

+ **Institutionalize experimentation rigor (ongoing):** Implement power analysis, minimum detectable effect standards, sequential testing controls, causal inference, and reproducibility checks. Require pre-registered hypotheses and success criteria.

+ **Scale impact & portfolio ROI** Produce a quarterly experimentation portfolio review quantifying incremental sales, margin, and member engagement; prioritize the roadmap to maximize ROI. **Success looks like:** X% QoQ increase in experiments tied to top OKRs; clear $ impact from in-club initiatives.

+ **Build and lead a high-** **performing** **team:** Hire, coach, and retain a blended team (data scientists, measurement scientists, and platform/analytics engineers). Establish high-quality code, review, and documentation standards; promote a culture of healthy debate, learning, and outcomes.

What** **You’ll** **Bring

+ **Experimentation & Causal Inference Expertise:** Deep experience designing and validating RCTs and quasi-experiments (e.g., diff-in-diff, synthetic controls, matching/stratification), power/MDE analysis, sequential testing control, variance reduction (e.g., CUPED), and heterogeneous effect analysis.

+ **Platform & Architecture Depth:** Proven track record building or scaling experimentation/measurement platforms (assignment, identity/bucketing, telemetry, metric computation layers, registry, readouts, and observability), ideally in high-scale product or retail environments.

+ **Hands-on Technical Skills:** Deep proficiency in Python for machine learning and statistical modeling, with strong experience using ML frameworks (e.g., TensorFlow, PyTorch, Scikit-learn) and data manipulation libraries (e.g., Pandas, NumPy). Skilled in SQL for feature engineering and large-scale data extraction. Committed to production-grade practices including code quality, automated testing, reproducibility, and model lifecycle management (MLOps).

+ **Business Acumen & Storytelling:** Ability to translate noisy signals into clear decisions; influence senior leaders with concise narratives that connect experiments to member outcomes and financial impact.

+ **Leadership & Change Management:** Experience building and mentoring teams, driving cross-functional adoption, and moving organizations from fragmented practices to consistent standards and self-service at scale.

+ **Domain Advantage:** Experience with **in-club/physical retail measurement** (traffic normalization, seasonality/weather controls, club clustering) is highly preferred.

+ **Education:** BS/MS/PhD in a quantitative discipline (e.g., Statistics, Economics, Computer Science) or equivalent experience.
