The Challenge
Potbelly is a 400+ location sandwich empire that's scaling digital and loyalty-and they need you to turn guest data into growth. You'll own the experimentation strategy that moves the needle on app adoption, retention, and loyalty program ROI.
Your Mission
Set up and run 3-5 statistically rigorous A/B tests across app/web/loyalty flows; document hypothesis framework and success metrics for team adoption
Map current guest journey across digital touchpoints; identify top 3 friction points causing drop-off in ordering or loyalty enrollment
Build 2-3 core dashboards tracking feature adoption, CRM engagement, and loyalty program KPIs; establish weekly reporting cadence with product/marketing
Define and align on 5-7 north star metrics for digital product roadmap with product and marketing leadership
Execute 12+ experiments; demonstrate 2-3 wins that materially moved app engagement or loyalty program performance (with lift %), scaled across network
Conduct 2 major post-launch feature analyses; translate insights into product roadmap recommendations that product leadership adopts
Build predictive models or segmentation around high-value loyalty members; inform targeted CRM campaigns that improve LTV or repeat visit frequency
Institutionalize experimentation culture; train product and marketing teams on statistical rigor; establish shared backlog of validated tests ready to scale
KPIs You'll Own
Feature Adoption Rate
% of app users who activate and repeat-use new digital features within 30 days of launch.
Loyalty Program Enrollment Lift
Incremental guests enrolled in loyalty program driven by CRM campaigns and app nudges vs. baseline.
A/B Test Statistical Significance
Proportion of tests run with proper sample size, power, and holdout design that achieve p<0.05 before scaling.
Guest Retention (Loyalty Cohort)
Repeat purchase frequency and repeat visit rate for loyalty members vs. non-loyalty baseline, tracked monthly.
Digital Order Mix %
% of total orders placed through app/web vs. in-store or phone; track adoption lift post-feature launch.
CRM Campaign ROI
Revenue or order lift per email/push campaign dollar spent; measured incrementally vs. control group.

Is This Role For You?
- You're fluent in experimentation design: you know sample size, power analysis, statistical significance, and holdout groups aren't optional
- You speak both product and marketing-you can translate CRM metrics to feature adoption and vice versa without losing the plot
- You've shipped real A/B tests that moved needle on engagement, retention, or revenue; you have battle scars from multivariate testing or complex attribution
- You're obsessed with guest behavior: funnels, cohort analysis, churn signals-and you ask 'why' three times before recommending a change
- You can own dashboards and SQL queries; you don't wait for reports, you pull your own data and iterate fast
- You need full remote-this is on-site in Chicago (though some remote flexibility outside restricted states)
- You're looking for hands-off execution-this role is 50% analysis, 50% stakeholder management and roadmap influence; you'll attend a lot of meetings
- You've never run a proper A/B test or don't understand p-values and statistical power-this is table stakes
