About JumpFly

JumpFly is an independent digital marketing agency that has helped businesses grow through paid media, SEO, marketplace advertising, email marketing, and digital strategy since 2003. We are expanding our Conversion Rate Optimization and Website Services capabilities and are hiring a Senior Web Optimization Engineer to help build and scale this new service line.

You combine CRO judgment with strong technical execution. You are comfortable across lead-generation and ecommerce experiences, use data to guide priorities, and look for repeatable solutions that improve delivery over time.

Required Qualifications

• 5 or more years of relevant web development, analytics implementation, or website optimization experience, or equivalent senior-level capability
• Hands‑on experience implementing and troubleshooting production website changes in WordPress and Shopify or a comparable ecommerce platform
• Strong GA4, Google Tag Manager, data-layer, conversion-tracking, and analytics implementation experience
• Demonstrated ability to conduct technical website audits and turn findings into prioritized recommendations
• Working familiarity with experimentation platforms, behavioral analytics, Core Web Vitals, technical SEO, and accessibility standards
• Strong technical judgment, troubleshooting, client communication, and experience safely delivering work across multiple website environments

Preferred Qualifications

• Additional experience with experimentation platforms, test design, or statistical analysis
• Additional experience with Shopify Liquid, Adobe Commerce, ecommerce analytics, or complex data-layer implementations
• Experience with New Relic, PHP, APIs, integrations, or visual-regression testing
• Agency or consultancy experience, including helping standardize or productize a web optimization service
