Senior CRO Manager

Role Overview

You will be the end-to-end owner of conversion rate optimization (CRO) at Ruby Labs, with a clear mission to deliver 15% conversion rate growth within a quarter. Unlike roles that only provide recommendations, you will run the full optimization cycle and own performance outcomes.

• Maintain high detail and quality throughout execution
• Analyze test results with statistical rigor to make confident scaling decisions
• Document learnings and maintain a systematic testing roadmap for continuous conversion growth
• Present insights and results to stakeholders to build alignment and momentum

Requirements

• 3+ years of hands-on CRO experience with measurable results (ideally subscription/SaaS funnels)
• Strong UI/UX sensibility and ability to create compelling, detailed mockups
• Analytical experience with tools such as Google Analytics, Mixpanel, and Growthbook (or similar)
• Strong attention to detail with a bias for action in fast-moving environments
• Ownership mindset: self-driven and accountable for performance outcomes
• Clear English communication (written and spoken)
• Bachelor’s degree in a relevant field

Nice to Have

• Experience with marketing attribution models, UTM parameters, and ROAS measurement
• Strong project management skills and ability to prioritize quickly
