About the role
We’re hiring a Conversion Rate Optimization (CRO) Manager to own the experimentation program that turns our paid traffic into signups, activations, and revenue. This role owns strategy and execution across the on‑site funnel—from the marketing site and landing pages to signup and partnering with onboarding—and is expected to find compounding conversion gains through a disciplined, data‑driven testing program.
The idóneo candidate is equally comfortable with the strategy and the execution: forming sharp hypotheses, designing statistically sound tests, building and QA’ing variants, reading results without fooling themselves, and engineering skills to build on‑page experiences. You obsess over funnel friction, statistical rigor, and velocity, and you know how to build an experimentation roadmap that ships. This role is highly cross‑functional and will partner closely with design, engineering, copy, performance marketing, lifecycle, and product to drive impact.
What you will do
- Own the CRO strategy and experimentation roadmap across the marketing site, landing pages,



and signup/onboarding funnels
- Form hypotheses from analytics, session data, and user research; prioritize tests by expected impact and effort
- Design, build, QA, and launch A/B and multivariate tests; ensure results are statistically sound
- Partner with design, engineering, and copy to spec and ship high‑quality variants quickly
- Analyze results, document learnings, and turn wins into durable improvements across the funnel
- Instrument funnel analytics and tracking so conversion impact is measurable end‑to‑end
- Align on‑site conversion with paid and lifecycle traffic in partnership with performance and lifecycle marketing
- Raise experimentation velocity and rigor as the program scales

Requirements
- Proven track record owning a CRO/experimentation program that delivered measurable conversion and revenue gains
- Hands‑on expertise with A/B testing and CRO tools (Optimizely, VWO, Googl
