About the Role We are seeking a data-driven, highly organized Marketplace Operations & Experimentation Specialist to join our Marketplace team and report to the Product Manager for Marketplace. This role presents an exciting opportunity to thrive in a dynamic, fast-paced environment within a growing team, with abundant prospects for career advancement.

The Marketplace is where shoppers discover stores, products, and deals inside the Sezzle app. Our team runs a lot of features, and there's almost always something being tested. You'll be the person who knows what's live, who it's live for, and how it's performing.

This is an operations role with a strong product and data lens. You'll launch and track A/B tests, keep an eye on our shopping partners, and turn results into clear recommendations on what we do next. You'll work closely with product, engineering, data, design, and partnerships. If you like running a lot of experiments at once and keeping every one of them organized, this role is for you.

The salary range for this role is $2,000 - $2,666 per month (Gross in USD) What You’ll Do Experimentation

Set up, QA, and launch A/B tests across Marketplace features. Make sure targeting, variants, and tracking are right before anything goes live. Monitor running tests, flag issues early, and call results once they reach significance. Keep a single source of truth for every test: what's live, who sees it, and what we learned.

Partner & Marketplace Operations

Create and manage placements, promotions, coupons, and offers across the Sezzle app. Set up and manage cashback programs in our internal admin tools.
