You will manage a continuous pipeline of A/B tests to increase statistically validated winners across the funnel. Working closely with data, product, and engineering teams, you will treat experimentation as a rigorous system rather than a list of ideas.

- Analyze funnels in Mixpanel to identify drop-offs and segment-specific opportunities
- Interpret results with statistical rigor to distinguish winners from noise
- Write detailed test specs and variant briefs for developers to build without ambiguity
- Create conversion-oriented copy and layout variants within compliance constraints
- Document every test in Notion with hypothesis, setup, results, and learnings
- Mentor a junior CRO specialist on test design and documentation standards
What you'll need
- 3+ years running A/B tests on D2C subscription or consumer web products
- Proficiency in Mixpanel or equivalent for building funnels and segmentation
- Working knowledge of statistics including significance, power, and sample size
- Experience with feature-flag or A/B testing platforms like GrowthBook or Statsig
- Ability to write and critique conversion copy based on behavioral psychology
- Daily use of AI tools such as Claude to accelerate concept and analysis work
