Senior Marketing Web Developer

eJam • Santa Ana, CA

About The Position

This is not just a coding job. It is for someone who wants to understand why things work, not just how to build them. We are looking for a Senior Marketing Web Developer to own the conversion surface of a multi-brand consumer products portfolio. You will build the landing pages, funnels, and checkout flows that our media spend runs into — and you will own whether we can trust the numbers that come back out. You will work in our Santa Ana office, five days a week, sitting alongside the media buyers and CRO team whose ideas you turn into deployed pages.

Requirements

• 4–6 years building conversion-focused web experiences — landing pages, funnels, or eCommerce storefronts — with a portfolio of pages you personally built.
• Strong command of HTML, CSS, and JavaScript fundamentals, with mobile-first responsive development as a default habit.
• Hands-on experience implementing and debugging tracking: GA4, GTM, Meta Pixel (ideally with Conversions API), TikTok Pixel.
• Shopify and Liquid theme development experience; comfort extending product, cart, and checkout experiences.
• Experience with custom checkout platforms — Checkout Champ, ClickFunnels, or comparable — or clear evidence you can pick one up fast.
• Practical fluency with AI coding tools, and the judgment to know their limits.
• Real CRO instincts: you can look at two variants and tell us why one won, and what invalidates a test.
• Willingness and ability to be in our Santa Ana office five days a week.

Nice To Haves

• Experience with Checkout Champ or a comparable custom checkout platform
• Server-side tracking / Meta Conversions API implementation
• Webflow experience or exposure to visual page builders
• Past DTC or eCommerce brand experience, in-house rather than agency
• Formal exposure to A/B testing tools and CRO methodology
• Experience with Figma and design handoff workflows

Responsibilities

• Landing page & funnel development. Conversion-focused pages from Figma, custom checkout flows and multi-step funnels in Checkout Champ, Webflow builds, and rapid A/B test variants in a high-velocity testing environment.
• Tracking & analytics integrity. Meta Pixel and CAPI, TikTok Pixel, GA4, Google Tag Manager. Every funnel tracks correctly at every step, and every test is measurable. This is yours to own, end to end.
• Shopify storefront customization. Theme modifications, custom Liquid sections, product page and checkout enhancements, and app integrations across three brands.
• CRO partnership. Reviewing funnel and campaign performance with the marketing team, contributing test ideas, and saying "I think we should try X" based on what you are seeing in the data.
• AI-assisted development. Using Claude Code, Cursor, v0, or similar to prototype and ship faster — with the judgment to know what to review and what to rewrite.

Benefits

• Work in-office with a top-performing DTC team in Santa Ana, CA
• Ownership of the full conversion surface across growing consumer brands
• Hands-on exposure to real revenue-driving projects and real performance data
• Opportunity to grow into lead and principal technical roles as the portfolio scales
• Competitive compensation and benefits package
