About the role

Build and run an experimentation engine: create hypotheses, plan and execute A/B and multivariate tests across landing pages, site flows, and some ads
Optimize landing pages & forms: improve message-market fit, UX, and page speed/Core Web Vitals; reduce drop-off on multi-step forms and booking flows
Tighten ad-page relevance: align creative, offers, and keywords with page copy and CTAs
Analyze and improve funnels: identify leaks across MQL to SQL to Deal to Won pipeline
Gain insights: blend GA4/Statcounter data with heatmaps, session replays, on-page polls, and user interviews to diagnose friction and implement solutions
Partner with paid acquisition, web design, and Sales to improve conversion across customer journey
Ship tests, scale winners, and roll out playbooks for page-speed and UX hygiene

5+ years in CRO/experimentation for high-traffic, high-spend environments (B2B lead gen strongly preferred)
Demonstrated wins improving lead-form CVR, CPL/CPA, booking rate, and SQL rate at meaningful scale
Fluency in test design & statistics (power analysis, sequential testing/Bayesian or frequentist, stopping rules, multiple-comparison discipline)
Hands-on with A/B tools (Convert, Google Ads Experiments, Meta A/B), analytics (GA4, StatCounter), tagging (GTM), heatmaps/session replays (Hotjar, Clarity), and CRO-friendly CMS/LP builders (WordPress/Elementor)
Strong copy chops and an eye for UX; can brief/QA design and dev and ship fast
Comfortable with data (pivot tables; basic SQL a plus) and Core Web Vitals implications for conversion
Proven experience with SEO +/- GEO or willingness to learn quickly
Willingness to work outside of core discipline across channels including ad creative and copy
Willingness to work on marketing projects outside scope of CRO projects
