Responsibilities
  • Build and maintain reusable components, page templates, and content models within Optimizely CMS to help marketing teams launch web pages efficiently.

  • 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.
