Job Description
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
