Role Summary

We’re looking for a Senior Growth Engineer who will lead Conversion Rate Optimisation and own experimentation across our platform. You’ll design, build, and analyse A/B tests that drive measurable conversion rate optimisation improvements across our driver and host journeys. This is a hands-on technical role sitting at the intersection of engineering, data, marketing and product. You won’t just follow a roadmap; you will help define it by proving what works.

What You’ll Do

• You operate with urgency and treat conversion rate as your responsibility, not someone else’s.
• Build and maintain the technical framework that allows us to run A/B tests without impacting site performance.
• Design and implement experiments across our host and driver journeys.
• Work across our frontend and backend to ensure tracking is accurate and tests are robust.
• Use analytics and heatmaps to challenge the status quo and propose high-impact experiments.
• Translate business goals into technical requirements, ensuring marketing and product objectives are technically feasible and secure.

Your Background

• 3+ years in Full-Stack or Frontend Development.
• Deep experience with Vue.js/Nuxt is essential.
• Familiarity with Laravel/PHP is a major advantage for deep-funnel experiments.
• You have a solid grasp of A/B testing statistics (p-values, significance, sample sizing).
• Experience with experimentation platforms.
• Comfortable with modern CI/CD (GitHub) and containerization (Docker).

Key Skills

• You focus on the 20% of effort that drives 80% of the impact.
• You prefer shipping and learning over perfect overengineered code.
• You can communicate concerns during the discovery phase, working with stakeholders to reach solutions that are both secure and commercially effective.
