Responsibilities Own the self-serve acquisition funnel from first visit to signup/trial. Lead CRO across key pages, run experiments, reduce friction, and partner with performance marketing to make sure paid traffic has somewhere effective to land. Develop and execute a strategy to protect and grow organic presence, covering both traditional SEO fundamentals and LLM/AI Engine Optimization (AEO).

Requirements 5+ years of growth, digital, or acquisition marketing experience, ideally at a developer-tools, SaaS, or API-first company with a PLG motion. Deep CRO instincts. You've optimized signup flows, run A/B tests on landing pages, and think in terms of conversion rates, not just traffic volume. Strong analytical skills. Comfortable in GA4 and Looker. You can pull your own data, spot anomalies, and build a narrative from numbers. SEO fundamentals and emerging AEO awareness. You understand how search is changing with zero-click results, AI overviews, and LLM referral traffic, and have ideas about how to adapt. WordPress CMS proficiency. Comfortable managing page content, URLs, and redirects, and collaborating with web developers to ship changes. Bias toward action with sound judgment. Able to ship things and make calls with imperfect data on a lean team, while knowing when something warrants deeper investigation.
