Description:

We are seeking a skilled Front-End Developer to join our team, focusing on setting up A/B tests within the Optimizely platform to drive experimentation programs on Client merchant websites. In this role, you will work closely with a strategist to bring innovative ideas to life on the web, ensuring engaging, high-performing user experiences. This role requires a strong command of CSS, JavaScript, and HTML, as well as excellent problem-solving skills and the ability to communicate technical details in simple terms when necessary.

Key Responsibilities:

• Work closely with a strategist to translate concepts into functional, testable web experiences, and effectively communicate technical insights to non-technical stakeholders (as needed)

• Own end-to-end A/B test configurations within Optimizely, including build, metrics definition, audience selection, URL targeting, and rigorous pre-/post-launch QA.

• Contribute to ongoing enhancements of the Client web widget product, identifying opportunities for improvements and proposing new features to drive innovation and better user experiences where feasible.

• Update widget code to create targeted widget experiences using session-based logic—such as new vs. returning, logged-in vs. logged-out, lapsed customers, and geo-based targeting—as well as other methods informed by the dataLayer, session storage, or local storage.

Qualifications:

• Minimum of 5 years of web development experience

• Bachelor’s degree or strong experience in Computer Science, Information Technology, or a related field.

• Strong proficiency in CSS, JavaScript, and HTML.

• Hands-on experience with the Optimizely platform (or other A/B testing platforms) and familiarity with A/B testing methodologies.

• Demonstrated problem-solving skills and ability to work both independently and collaboratively.

• Strong communication skills, especially in translating complex technical information into accessible language.
