We offer a diverse range of opportunities across the health, education, and entertainment industries. Our innovative teams are driving the future of consumer-led products, and we're always looking for passionate individuals to join us. Learn more about our story at: com/about-us/ About the role 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. Responsibilities - 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. Qualifications - 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. Nice to Have - 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 We Offer - Direct mentorship from a Senior CRO Manager and a full view of how a high-volume experimentation process runs. - Ownership that grows with results: start with execution, earn your own tests. - Autonomy and speed: small team, fast decisions, no bureaucracy. - The latest AI tools as a core part of daily work, not a side experiment. - Room to grow into a CRO Specialist role as you deliver. Location Ruby Labs operates within the CET (Central European Time) zone. Applicants from any country are welcome to apply for the position as long as they are located within approximately ± 4 hours of CET. This ensures optimal collaboration and communication during working hours. Benefits Discover the perks of being part of our vibrant team!
