Job summary

Ruby Labs is seeking a hands-on Senior CRO Manager to drive conversion growth for a core D2C subscription product. You’ll own a continuous pipeline of A/B tests from hypothesis to launch, collaborating with data, product, and engineering teams to validate winners and optimize the funnel.

You will lead the testing program with a systems mindset, ensuring hypotheses are tested with proper diligence, documented verdicts, and scalable learning across devices and locales.

Qualifications

• CRO / Experimentation: 3+ years running A/B tests on a D2C subscription or consumer web product, with results you can attribute to your own work.
• Product Analytics: Hands-on proficiency in Mixpanel or a close equivalent - building funnels, segmenting by device and geography, and reading cohort behaviour without analyst support.
• Statistics: Working knowledge of significance, power, sample size, and common pitfalls such as peeking and sample ratio mismatch.
• Experimentation Platforms: Experience with a feature-flag or A/B testing platform (GrowthBook, Statsig, or close equivalents).
• Conversion Copy & UX: Ability to write and critique conversion copy and page layouts, grounded in behavioural psychology.
• AI Tooling: Active daily use of AI tools (Claude or equivalent) to accelerate concept, analysis, and prototype work.
• Compliance: Familiarity with consumer protection rules for subscription products and marketing claims is a bonus.

Responsibilities

• Own the A/B test backlog from hypothesis to launch and prioritise ideas by impact, confidence, and effort.
• Analyse funnel performance and identify drop-offs and opportunities across devices and locales.
• Read results with statistical rigour, distinguish winners from noise, and document verdicts for sign-off.
• Write test specs and briefs so developers can implement without back-and-forth.
• Create conversion-oriented copy and layouts within product compliance.
• Document every test in Notion with hypothesis, setup, results, and learnings; support leadership reporting.
• Mentor a junior CRO specialist in test design, analysis, and standards.
