London Office - Hybrid: 4 days in the office, 1 day working from home
At Ebury, we don’t just build marketing sites; we build experimentation engines. We’ve launched a sophisticated Webflow instance that serves as the global front door to our fintech platform. Your mission is to use Webflow Optimize and custom code to run hundreds of simultaneous AI-driven experiments and ML-powered personalizations without breaking the user experience.
You will sit at the intersection of growth engineering and AI optimization.
Scale Infrastructure: Build and manage concurrent A/B tests and personalization campaigns using Webflow Optimize.
Bridge the Gap: Extend Webflow with JavaScript, APIs, and custom integrations to connect our marketing site with our core product and analytics stack.
Own Conversion: Work cross-functionally with Product, Marketing, and Data teams to design, instrument, and analyze growth experiments.
Build Systems: Create reusable components and design systems that enable the marketing team to launch campaigns at pace while maintaining brand consistency.
Experience: 3–5 years of web development experience with a mastery of frontend fundamentals (JavaScript/TypeScript, HTML, CSS).
Webflow Expertise: You have built production-grade sites in Webflow and know how to extend the platform using custom code, APIs, and complex integrations.
Fullstack Fundamentals: Comfortable managing APIs, authentication, and data flows to connect frontend experiences with backend systems.
Data-Driven Mindset: You instrument tracking and analyze results to make technical decisions based on data rather than opinions.
Growth Mindset: Experience on a growth team, running A/B tests, or being responsible for conversion metrics. You understand that "good code" is code that moves business KPIs.
Experimentation Tools: Experience with Webflow Optimize or similar platforms (Optimizely, VWO, etc.).
Specialized Background: Experience in Growth Engineering, Conversion Rate Optimization (CRO), MarTech, B2B SaaS, or Fintech.
AI/ML: An understanding of ML/AI-powered personalization.
We need someone who thinks like a Product Engineer but loves the fast pace of Growth. You will thrive here if you:
Ship Fast: You get energized by deploying experiments quickly and seeing immediate impact on conversion metrics.
Collaborate: You enjoy working cross-functionally with Marketing, Product, and Data teams.
Balance Speed & Quality: You know when to "hack" for a quick test and when to build for long-term scale.
Seek the "Why": You want to understand the business goals behind a project, not just close out tickets.
Stay Adaptable: You have "strong opinions, loosely held"—advocating for technical quality but pivoting based on data.
You prefer focusing on backend infrastructure over frontend-heavy roles.
You dislike ambiguity and require perfectly defined requirements for every task.
You only want to work with other engineers; this role is embedded in Marketing and Product.
You view Webflow as "not real coding" rather than a powerful platform to be extended with custom code.
