About
Genesis Digital is the company behind Kartra, WebinarJam, and EverWebinar. Our software helps business owners take their expertise online and attract clients at scale.
We're hiring a part-time developer (20 hours/week, ongoing) to support our marketing team by building and launching WordPress pages, improving website performance, and supporting technical SEO initiatives across our WordPress marketing sites.
This is an execution-focused role. You will frequently develop and launch new pages based on designs created by our Lead Web Designer, and you will also help optimize site speed and performance (Core Web Vitals, JavaScript cleanup, script loading improvements).
You should be comfortable working in an existing WordPress environment—specifically WP Engine + GreenShift—and supporting ongoing marketing experiments (A/B tests) using VWO.
TOP PRIORITIES:
1) Build & Launch New WordPress Pages
-Develop and launch new landing pages based on designs from our Lead Web Designer
-Implement layout updates and page improvements quickly and accurately
-Ensure pages are responsive, clean, and maintainable
-Add or adjust custom CSS and inline JavaScript within the GreenShift/WordPress environment when needed (without breaking responsiveness or performance)
2) Site Performance + Technical SEO Optimization
-Improve page load performance and mobile experience
-Optimize Core Web Vitals (especially FCP / LCP)
-Identify and remove/replace legacy or bloated JavaScript
-Improve script loading order (defer/async where appropriate) and reduce render-blocking behavior
-Diagnose performance issues using tools like PageSpeed Insights / Lighthouse and implement real fixes
-Ensure changes do not break layouts, styles, or functionality
3) Experiment Support (A/B Testing via VWO)
-Work from test plans and direction provided by our performance/CRO leads, and help implement and QA test setups inside VWO
-Support ongoing iteration cycles and clean handoffs
-Help ensure experiments can be reused and scaled across multiple sites when possible
4) Checkout Flow Optimization
-Work within the limitations of the native Kartra checkout flow, focusing on optimizations we can control at the page and front-end level
-Contribute to solutions such as custom checkout landing pages or embedded checkout components when greater layout/performance control is needed
-Ensure checkout improvements can be reused across multiple brands when possible
REQUIRED SKILLS
-Strong WordPress development experience, including real-world performance optimization
-GreenShift experience preferred (or similar block-based builder, with proof you can ramp quickly)
-WP Engine experience strongly preferred
-Strong JavaScript skills (debugging + optimization, not just basic edits)
-Working knowledge of PHP (themes, safe implementation, troubleshooting)
-Experience with technical SEO as it relates to performance (Core Web Vitals, JS execution, render behavior)
-Strong attention to detail when translating design files into live pages
TO APPLY, PLEASE INCLUDE:
-A short note confirming your experience with GreenShift and WP Engine
-1–2 examples of landing pages you've built in WordPress (links preferred)
-1–2 examples of performance optimization work you've done (Core Web Vitals improvements preferred — include before/after if possible)
-Your hourly rate + weekly availability
Contract duration of more than 6 months. with 40 hours per week.
Mandatory skills: WordPress, JavaScript, PHP, Web Development, Website
