About The Position

Ruby Labs is looking for a Senior CRO Manager who is passionate about conversion optimization, possesses strong UI/UX instincts, and can work at a fast pace. This role involves owning the entire optimization loop, from data analysis and hypothesis generation to creating high-fidelity mockups, collaborating with engineers, and achieving performance outcomes. The position operates in a fast, iterative environment where experiments are shipped, learnings are applied, and the optimization process is continuous. The company offers a compensation structure that rewards high performers with financial upside tied to their impact.

Requirements

Proven CRO results: 3+ years of hands-on CRO experience, ideally with subscription or SaaS funnels, with documented performance lifts.
AI-native workflow: You actively integrate AI into your daily process — prompting, prototyping, analyzing, drafting — and have opinions about what actually works. Almost a must.
Design taste: Strong UI/UX sensibility and the ability to recognize and create ideas that convert. You can build compelling, detailed mockups yourself.
Speed and iteration: Bias for shipping. You'd rather get two well-designed tests live today than one perfect test in a week, and you keep the cycle moving.
Analytical depth: Skilled in Google Analytics, Mixpanel, Growthbook, or similar.
Execution excellence: Remarkable attention to detail in fast-moving environments.
Ownership: Self-driven, proactive, fully accountable for outcomes.
Fluent English: strong written and verbal communication.

Nice To Haves

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.

Responsibilities

Run end-to-end optimization cycles: research → hypothesis → design → test → rollout — and keep the cycles short.
Use AI tools daily to accelerate research, ideation, mockup creation, analysis, and documentation.
Perform deep funnel analysis and competitive benchmarking to surface high-impact opportunities.
Design high-fidelity UI/UX mockups that clearly communicate your vision while protecting brand integrity.
Partner with engineers to ensure flawless test implementation and rapid deployment.
Analyze results with statistical rigor and make confident scaling decisions.
Document learnings and maintain a continuously prioritized testing roadmap.
Present insights and results clearly to stakeholders, building alignment and momentum.
