• Familiarity with experimentation across both web and app platforms, or strong aptitude to pick up app-based testing approaches.
• Experience directing or coordinating the work of other engineers or delivery partners.
• Familiarity with tagging and analytics implementation (e.g., GA4, Adobe Analytics, tag management systems).
• Highly detail-oriented with a strong QA mindset.
• Comfortable coordinating work across internal teams, Product engineering, and external delivery partners.
• Strong organizational skills to manage multiple concurrent experiment builds across regions and platforms.

Responsibilities

• Lead the build and QA of A/B and multivariate tests across global regions.
• Build experiment variants based on approved designs for web and app.

• Direct and coordinate 3rd-party delivery partners for additional build capacity, ensuring their work meets internal standards.
• Coordinate with internal IT resources on more complex technical builds.
• Troubleshoot and resolve technical issues with live experiments.
• Own QA for every experiment, including implementing and validating tracking/tagging prior to launch.
• Coordinate with the IT/QA team on regression and cross-site testing.
• Monitor active experiments for conflicts across concurrent tests.
• Work closely with CRO Managers to align on build priorities, timelines, and tracking/measurement setup.
• Partner with UX and Design to ensure experiments are built to spec.
• Support the handoff of successful tests to Product Management for permanent implementation.
• Stay up to date with testing platform capabilities, tools, and best practices.
• Proactively suggest process or tooling improvements to increase build efficiency and quality.
