Merchandising Operations Associate

THE POSITION

The Merch Ops Experimentation Associate supports the merchandising experimentation program across Fan Duel Sports book and Predicts, partnering closely with the Senior Associate, Experimentation and the Merch Ops Sr. Director. This role sits at the heart of how we test, learn and ship improvements to the customer experience - from A/B tests to multivariate and multi-armed bandits - covering the full experimentation lifecycle at a smaller scale, with guidance from more senior team members on design nuance and go/no-go decisioning.

The Associate will help run experiments end-to-end across both surfaces — Sports book merchandising (parlay module, pre-packaged bets, market templates, SGP/SGP+, X-Event) and Predicts (prediction markets UX, module placement, event discovery). They'll partner cross-functionally with Product, Risk & Trading, Tech, Commercial, and UX Analytics to build, QA, monitor, and report on tests, keeping the pipeline visible and the learnings flowing back into the roadmap.

In addition to the specific responsibilities outlined above, employees may be required to perform other such duties as assigned by the Company. This ensures operational flexibility and allows the Company to meet evolving business needs.

• Experimentation Backlog — Support the Senior Associate in grooming and maintaining the testing backlog across Sports book and Predicts, helping keep ideas, hypotheses and priorities clearly documented and visible to stakeholders.
• Intake & Triage — Be a first point of contact for experiment ideas coming from Product, Commercial and Marketing, capturing requirements and surfacing feasibility questions for senior review.
• Cross-functional Collaboration — Work with UXA, Product, Risk & Trading, Commercial and Tech to shape sound experiment designs that balance user value with commercial outcomes across both Sports book and Predicts.
• Setup & Launch — Configure tests in Fan Duel's CMS (Sanity) and experimentation platform (Amplitude), coordinate with Product/Tech on feature-flag readiness, and execute Merch Ops QA before every launch.
• Ongoing Monitoring — Run regular health checks on in-flight experiments — tracking accuracy, sample size pacing, guardrail metric stability — and elevate anomalies to the Senior Associate and partner teams quickly.
• Measurement & Reporting — Partner with UXA to pull results, review statistical significance and business impact, and help build readouts and dashboards that make outcomes easy to consume.
• Communication — Keep stakeholders updated via Slack, Confluence and quarterly summaries, maintaining clear records of in-flight and completed tests across Sports book and Predicts.
• Analysis & Decisioning — Contribute analysis and point-of-view to go/no-go rollout discussions, with senior team members owning the final call, and help standardize learnings back into the Merch Ops knowledge base.
• Industry-leading Merchandising — Collaborate with the wider Merch Ops team to help keep the Fan Duel Sports book and Predicts experiences best-in-class in design, usability and commercial effectiveness.
