Job summary

Ruby Labs is seeking a Senior CRO Manager to own the A/B testing pipeline for a core D2C subscription product. You will partner with data, product, and engineering to hypothesize, prioritise, launch, and document verdicts on tests that move the funnel.

The role is a flexible independent contractor with remote work, CET-aligned collaboration, and high impact potential. You will mentor a junior CRO specialist and drive a culture of rigor and measurable growth.

Responsibilities

• Experiment Pipeline: Own the A/B test backlog from hypothesis to launch. Prioritise ideas by expected impact, confidence, and effort, and keep the pipeline full so live traffic is always being used to learn.
• Funnel Analysis: Analyse the funnel in Mixpanel to find drop-offs, friction points, and segment-specific opportunities across devices and locales, and turn them into testable hypotheses.
• Test Analysis & Verdicts: Read results with statistical rigour, separate winners from directional trends and noise, and prepare clear verdicts for sign-off with the data team.
• Test Specification & QA: Write test specs and variant briefs that developers can build without follow-up questions, and check every variant before and after launch.
• Conversion Copy & Layouts: Produce conversion-oriented copy and layout variants that stay within compliance constraints on product claims.
• Documentation & Reporting: Keep every test documented in Notion with hypothesis, setup, result, and learning, and contribute to regular experimentation reporting for leadership.
• Mentoring: Support a junior CRO specialist on test design, analysis, and documentation standards.
