Role Overview

As a Conversion & A/B Testing Specialist, you’ll design, run, and analyze A/B/MV/personalization experiments across web and mobile to lift conversion and engagement.

This is a remote role with close collaborating with product, design, and engineering experts. Availability during US Pacific Time (PT) hours is required. If you’re passionate about optimizing digital experiences through testing and data-driven insights, and enjoy getting your hands dirty to make experiments happen, we’d love to hear from you!
