Front-End Development and Conversion Rate Optimization; CRO Manager

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 ideal 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.

• 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

• 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, Google Optimize successors, Statsig, Growth Book, or similar), web analytics (GA4, Amplitude, Mixpanel, or similar), and front‑end development (HTML, CSS, and JavaScript)
• Strong analytical rigor—you understand statistical significance, sample size, and how to avoid false positives without a second opinion
• Experience optimizing signup, onboarding, and landing‑page funnels for both self‑serve and lead‑gen motions
• Comfortable working closely with design, engineering, and copy to ship high‑quality test variants
• Clear communicator who can turn data into decisions and bring the team along
• You thrive in scrappy, high‑ownership environments and are confident building a program from the ground up

• Experience with server‑side testing or feature‑flag‑based experimentation
• Experience marketing to technical audiences (e.g., developers, APIs, infrastructure)
• Experience standing up experimentation infrastructure or collaborating with data/BI teams

We believe in hiring the best talent in the world to make an impact in the right role at the right time. At Eleven Labs, strong performance creates opportunities for growth. Here are some of the career paths you can expect after excelling in this role:

• Lead the experimentation function across the full funnel as the team scales
• Expand into broader growth or growth‑product leadership
• Move into full‑funnel growth strategy or a channel‑owner leadership role

This role is remote‑first, so it can be executed from anywhere in NA and EU. If you prefer, you can work from our offices in Dublin, London, New York, and Warsaw.
