Head of CRO

Company Overview

Holafly is a high-growth scale-up revolutionising how travellers connect to the internet abroad. Since 2018, we’ve enabled connectivity in 200+ destinations with reliable eSIM solutions.

With a team of 500+ people across multiple countries, we are scaling globally with one clear mission: deliver seamless, unlimited data and total peace of mind to travellers worldwide.

Role

We are looking for a Head of CRO to build and scale a best-in-class experimentation engine across web and mobile apps.

This role goes beyond traditional CRO. You will own how we experiment, release, and optimize user experiences at scale, with a strong focus on mobile apps (iOS & Android).

You will leverage feature flags, experimentation frameworks, and A/B testing systems to continuously improve conversion, user flows, and product experience.

You will operate at the intersection of Product, Marketing, and Engineering, driving fast iterations that directly impact revenue and user satisfaction.

Key Responsibilities

• Own and scale the CRO & experimentation program across app and web
• Lead mobile-first optimization, improving conversion across app journeys
• Implement and manage feature flag systems to enable fast, safe releases
• Design and run high-quality A/B tests and experimentation frameworks
• Identify friction across the full funnel: onboarding, purchase, upsell, retention
• Deep dive into user behavior: funnels, cohorts, drop-offs, session analysis
• Drive continuous improvements in UX, usability, and conversion flows
• Partner closely with Product and Engineering to ship experiments fast
• Build and lead a cross-functional CRO team (experimentation, analytics, ops)
• Establish a company-wide experimentation culture (speed + rigor)
• Define clear measurement of impact on conversion rate and revenue
  
  

Qualifications

• 8–12+ years in CRO, Growth, or Product Growth roles
• Strong experience optimizing mobile apps (iOS & Android)
• Proven track record improving conversion at scale in B2C products
• Hands-on experience with feature flags (e.g. LaunchDarkly, Firebase, Statsig)
• Strong expertise in A/B testing frameworks and experimentation systems
• Deep understanding of UX, user behavior, and funnel optimization
• Experience working closely with Product & Engineering teams
• Strong analytical skills (Amplitude, Mixpanel, GA4, etc.)
• Fluent in English
  
  

What Sets You Apart

• You have built or scaled experimentation platforms, not just run tests
• You understand how to combine feature flags + experimentation
• You are obsessed with removing friction in mobile experiences
• You move fast and prioritize shipping over perfect analysis
• You have delivered measurable conversion and revenue impact
• You thrive in fast-paced, high-growth environments
  
  

Why Join Holafly

• Massive global scale in a fast-growing category
• Direct impact on revenue and core product experience
• Work closely with leadership and shape the growth engine
• High ownership, fast execution, low bureaucracy
  
  

During a trip to Thailand, Pedro and Lidia, the founders of Holafly, experienced the frustration of not having an internet connection.

Inspired by their own experiences, they came up with a simple but brilliant idea: why not allow travellers to buy data plans for any destination from their home country?

Our passion for providing easy and convenient connectivity to travellers around the world drives everything we do.

We love our work and we do it with pride. Stay connected wherever you go.
