The role

Ruby labs is looking for a Senior CRO Manager - someone who lives and breathes conversion optimization and delivers measurable results. In this role, you'll have a clear mission: deliver 15% conversion rate growth in a quarter.

Unlike companies where CRO specialists simply make recommendations, you'll drive the entire process: from data analysis and hypothesis generation to creating high-fidelity mockups, collaborating with developers on implementation, and ultimately owning the performance outcomes.

We've built a compensation structure that directly rewards those who exceed targets - top performers see substantial financial growth tied directly to their impact. If you're ready to apply your optimization talents in an environment where excellence is expected and rewarded, we want to talk to you.

What you'll do

  • Lead end-to-end optimization cycles: research → hypothesis → design → testing → rollout.

  • Perform deep funnel analysis and competitive benchmarking to uncover high-impact opportunities.

  • Design high-quality UI/UX mockups that clearly communicate your vision and maintain brand integrity.

  • Partner with engineers to ensure flawless test implementation and deployment.

  • Maintain uncompromising attention to detail and quality throughout the process.

  • Analyze test outcomes with statistical rigor, making confident scaling decisions.

  • Document learnings and build a systematic testing roadmap for continuous conversion growth.

  • Present insights and results clearly to stakeholders, building alignment and momentum.

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.
