The Challenge

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.

The Role

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.

What We’re Looking For

Must-Have Qualifications

• 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.

Bonus Points (We Will Teach You)

• 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.

What Matters Most

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 Won’t Thrive Here If...

• 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.
