Job Description

Ruby Labs is looking for a 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. At Ruby Labs, 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.

Job Responsibility

  • Lead end-to-end optimization cycles: research → hypothesis → design → testing → rollout
  • Conduct in-depth funnel analysis and competitive benchmarking to identify 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

Requirements

  • Proven CRO Results: 3+ years of hands-on CRO experience, ideally with subscription or SaaS funnels, with documented performance lifts
  • Design Sensibility: Strong UI/UX understanding, able to create compelling, detailed mockups
  • Analytical Expertise: Skilled in platforms such as Google Analytics, Mixpanel, Growthbook (or similar)
  • Execution Excellence: Remarkable attention to detail with a bias for action in fast-moving environments
  • Ownership Mentality: Self-driven, proactive, and comfortable being fully accountable for performance outcomes
  • Communication: Clear, persuasive communicator with strong English skills (written and spoken)
  • Fluent English: Strong written and verbal communication skills

Nice to have

  • Experience with BI tools (Tableau, Looker, or similar)
  • Exposure to marketing attribution models, UTM parameters, and ROAS measurement
  • Strong project management skills with the ability to prioritize and execute quickly
  • Bachelor’s degree in a relevant field

What we offer

  • Remote Work Environment: Embrace the freedom to work from anywhere, anytime, promoting a healthy work-life balance
  • Unlimited PTO: Enjoy unlimited paid time off to recharge and prioritize your well-being, without counting days
  • Paid National Holidays: Celebrate and relax on national holidays with paid time off to unwind and recharge
  • Company-provided MacBook: Experience seamless productivity with top-notch Apple MacBooks provided to all employees who need them
  • Flexible Independent Contractor Agreement: Unlock the benefits of flexibility, autonomy, and entrepreneurial opportunities. Benefit from tax advantages, networking opportunities, reduced employment obligations, and the freedom to work from anywhere
