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.

About the Role

The Senior CRO and Web Optimization Engineer is not a traditional software engineering role. We're looking for a hands-on web optimization expert with direct experience in CRO, GA4/GTM, WordPress, and ecommerce who can identify conversion opportunities, prioritize solutions, and implement them.

Ideal Candidate Profile
The ideal candidate is a senior, hands-on web optimization expert who can move from analysis to action. You can quickly understand how a website works, identify the most meaningful opportunities, explain your recommendations to clients, and implement improvements safely.

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 HTML, CSS, JavaScript, and browser-debugging skills, with experience building responsive, production-ready web experiences
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

If you do not meet all the above requirements STOP!
DO NOT APPLY FOR THIS POSITION!

Core Responsibilities

Conduct technical website audits covering architecture, CMS constraints, analytics, conversion paths, performance, accessibility, integrations, and implementation risks
Implement, audit, and troubleshoot GA4, Google Tag Manager, data-layer events, form tracking, conversion tracking, and ecommerce tracking; establish reliable baseline metrics
Implement approved CRO and website improvements, including landing pages, forms, navigation, checkout flows, responsive layouts, and reusable components
Estimate effort, identify dependencies and risks, and recommend maintainable implementation approaches
Present findings clearly and participate in client discovery, scoping, planning, and troubleshooting when technical or CRO expertise is needed
