What is a CRO developer?

A CRO Developer is a specialist who focuses on Conversion Rate Optimization (CRO) for websites and digital products. Their main role is to implement and test changes to web pages—using tools like A/B testing and analytics—to increase the percentage of visitors who complete a desired action, such as making a purchase or filling out a form. CRO Developers work closely with marketing and UX teams to identify pain points in the user journey and apply data-driven solutions. They typically possess skills in front-end development, analytics platforms, and user experience principles. By continuously optimizing websites, CRO Developers help businesses achieve better results from their online traffic.

What are some of the common challenges faced by a CRO developer when optimizing conversion rates across different platforms?

CRO Developers often encounter the challenge of ensuring that conversion optimizations are effective across various devices, browsers, and user segments. Balancing speed of implementation with thorough A/B testing and data analysis can also be demanding, as changes must be both technically sound and data-driven. Additionally, collaborating closely with designers, marketers, and analysts is essential to align technical solutions with broader business goals, which requires strong communication skills and adaptability.

What are the key skills and qualifications needed to thrive as a CRO developer?

To thrive as a CRO Developer, you need expertise in web development (HTML, CSS, JavaScript), A/B testing methodologies, and a solid understanding of conversion rate optimization principles, often supported by a relevant degree or certification. Familiarity with tools like Google Optimize, Optimizely, VWO, Google Analytics, and tag management systems is typically required. Strong analytical thinking, attention to detail, and effective communication skills help you collaborate with marketing and design teams to drive impactful testing strategies. These skills and qualities are crucial for improving user experience and maximizing website conversion rates, directly impacting business growth.

  • Develop and support integrations between Optimizely CMS and enterprise platforms such as Salesforce, Marketo, Adobe Commerce, and internal systems.
  • Create and deploy advanced A/B, split, and multivariate tests in Optimizely Web Experimentation, including custom DOM manipulation and dynamic content changes.
  • Implement personalized web experiences for targeted B2B audiences and account-based marketing campaigns.
  • Partner on server-side testing and feature flagging when frontend testing is not the best fit.
  • Perform thorough cross-browser and cross-device testing to help ensure smooth, consistent user experiences with minimal flicker or layout shift.
  • Define and document best practices, technical standards, and governance guidelines for Optimizely-related work.
  • Collaborate closely with CRO, product, and design teams to evaluate ideas, prototype solutions, and translate designs into polished digital experiences.
  • Use AI-assisted development tools to accelerate coding, debugging, testing, and experimentation workflows.
Skills
  • 5+ years of full-stack web development experience.
  • At least 3+ years of hands-on experience working within the Optimizely ecosystem.
  • Strong backend development skills with C# and .NET Core/MVC, especially in Optimizely CMS environments.
  • Advanced frontend experience with HTML5, CSS3/SASS, and JavaScript, including Vanilla JS, ES6+, jQuery, React, or Vue.
  • Deep understanding of Optimizely platform concepts such as Project JS, visual tags, audience targeting, anti-flicker approaches, and caching behavior.
  • Experience building for complex B2B websites, including lead generation and gated content workflows.
  • Strong Git knowledge and familiarity with modern CI/CD workflows such as Azure DevOps or GitHub Actions.
  • Ability to work independently while also partnering effectively with cross-functional teams.
  • A proactive, solution-oriented mindset with a focus on speed, quality, and continuous improvement.
Preferred Skills
  • Active Optimizely Developer certification in CMS or Web Experimentation.
  • Experience supporting server-side experimentation and feature flagging initiatives.
  • Familiarity with UX/UI collaboration and translating wireframes or Figma designs into interactive experiences.
  • Comfort using AI tools such as GitHub Copilot or ChatGPT to support development efficiency.
  • Experience working in remote-first environments and collaborating across multiple locations.

Horizontal is committed to fostering an inclusive environment where all qualified candidates can thrive. We value diversity, equity, and inclusion as essential to building strong teams, better ideas, and better outcomes.
