Full Job Description

📋 Description

• We are building a category-defining document management platform and are looking for a Senior CRO Manager who thrives on ownership, speed, and building things that scale.
• You'll own the full optimization loop end-to-end: deep funnel analysis, hypothesis generation, high-fidelity wireframes and visual specs, working directly with engineers, and the performance outcomes that follow.
• We are not just looking at landing page optimizations, in this role you'll be working across the entire user journey, from acquisition through activation, retention, and monetization.
• The pace is fast and iterative. We ship in days, learn, and keep the engine running.
• We've built a compensation structure that directly rewards people who exceed targets. Top performers see meaningful financial upside tied to their impact.
• Own end-to-end optimization cycles: research → hypothesis → design → test → rollout, while keeping the cycles short.
• Use AI tools daily to accelerate research, ideation, design, analysis, and documentation.
• Perform deep funnel and product analysis across the full user journey - acquisition, activation, retention, monetization - plus competitive benchmarking to surface high-impact opportunities.
• Design high-fidelity wireframes and visual specs 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.

🎯 Requirements

• Proven CRO results: 3+ years of hands-on CRO experience, ideally with subscription or SaaS funnels, with documented performance lifts.
• Funnel + product thinking: You don't just optimize landing pages. You think about the full user journey and how product decisions compound with funnel decisions.
• AI-native workflow: You actively integrate AI into your daily process - prompting, prototyping, analyzing, drafting - and have opinions about what actually works.
• Design taste: Strong UI/UX sensibility and the ability to recognize and create ideas that convert.
• 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 Mixpanel, GrowthBook, Google Analytics, 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.

🏖️ Benefits

• 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.
