Junior CRO Manager

Who you are

• 1+ years of hands-on experience in CRO, growth, product, or digital marketing - you've built pages, run or supported tests, or shipped funnel changes before
• Design sense: you can tell a clean, convincing page from a cluttered one, and you can build one yourself with the tools at hand
• Bias for shipping: you'd rather get a solid variant live today than polish it for a week, and you keep the cycle moving
• Proactive: you don't wait for the next ticket; you spot what needs doing and do it
• Strong English: clear written and verbal communication. You'll write hypotheses, tickets, and summaries daily
• Good judgment on conversion opportunities: you can look at a landing page or funnel step and sense what's worth testing and why
• Comfortable with ambiguity: priorities shift, briefs are incomplete, and data is messy. You make a sensible call and keep moving
• AI-native habits: you already use Claude or similar tools in your work and want to push further
• Attention to detail: experiments live or die on setup, and you check twice
• Experience with landing page builders, no-code tools, or basic HTML/CSS
• Familiarity with Mixpanel, Google Analytics, GrowthBook, or similar
• Exposure to subscription or SaaS funnels
• Bachelor's degree in a relevant field

What the job involves

• RubyLabs is looking for a hands-on Junior CRO Manager to join one of our product growth teams
• You'll work directly with our Senior CRO Manager, turning a fast-moving testing roadmap into live experiments, new landing pages, and new funnels
• This is an execution role first
• You'll take hypotheses from idea to live test - building the designs yourself with AI tools, setting up the experiments, and keeping the pipeline moving - while bringing your own test ideas to the table
• The more your judgment proves out, the more of the roadmap you own
• Build new landing pages and funnels: create alternative landing page variants and funnel flows to test messaging, structure, and offers
• Prepare designs with Claude: turn hypotheses into experiment mockups and variants using AI tools, without waiting on a designer
• Set up experiments: configure A/B tests, define success metrics, and verify tracking before anything goes live
• Manage the experiment pipeline: keep tickets clear and prioritized, brief engineers, and follow each test from setup to rollout
• Contribute test ideas: study the funnel, competitors, and user behavior, and bring hypotheses to the roadmap alongside the senior's
• Support analysis and documentation: help read results, document learnings, and keep the testing roadmap current
