Senior Checkout Champ Developer

About the Company

AJ Media is a performance-driven ecommerce growth agency scaling consumer brands toward $100M. Our engineering team builds the checkout systems, upsell flows, and funnel logic that convert traffic into revenue. We focus on conversion rate, average order value, and repeatability — every line of code has a business outcome attached to it.

About the Role

This is the senior technical leadership role for our Checkout Champ and Shopify funnel stack. You will own architecture end-to-end — from spec to production deploy — across multiple consumer brands (Gekko Gifts, Purvos, Besyner) with more launches planned. You will lead complex builds, mentor a junior developer, and have final sign-off on QA and production releases.

Responsibilities

• Checkout Champ: End-to-end Checkout Champ funnel architecture and strategy; custom subscription flows and complex rebill logic; build and configure upsell/downsell sequences, order bumps, and post-purchase flows at a strategic level; payment gateway configuration and advanced troubleshooting; final QA sign-off and production deploys.
• Shopify: Full ownership of Shopify theme architecture, Liquid development, and storefront customization across brands; lead API integration work from spec through deployment; resolve complex display/functional issues; oversee third-party app configuration and integration strategy.
• Tracking & Performance: Own pixel and tracking architecture (Meta, Google, native platform events); diagnose and resolve tracking discrepancies; translate checkout flow changes into measurable conversion impact working closely with media buying.
• Team Leadership: Direct and mentor a Junior Checkout Champ Developer — assign scoped tasks, review work, and develop their path to ownership; set technical standards, documentation practices, and code review processes; review release notes and assess impact across the stack.

Qualifications

• 4+ years hands-on experience with Checkout Champ, including ownership of multiple live, high-traffic funnels.
• Advanced Shopify expertise — Liquid, theme architecture, storefront customization, app ecosystem.
• Strong JavaScript and front-end development skills (HTML, CSS).
• Proven experience designing subscription/rebill logic and complex payment gateway configurations.
• Track record of API integration work from spec to deployment.
• Deep understanding of conversion funnels and how technical decisions affect CRO / AOV metrics.
• Experience mentoring or leading junior developers and excellent written communication — async-first clarity is non-negotiable.
• Portfolio is mandatory: applications without Checkout Champ and Shopify project examples will not be reviewed. Provide multiple Checkout Champ funnels you've architected (screenshots, Loom walkthroughs, or live links), Shopify projects demonstrating advanced theme/Liquid work, and examples of API integrations you led from spec to deployment.

Strong Plus

• Experience with post-purchase upsell apps (ReConvert, Zipify, or similar).
• Familiarity with subscription platforms (Recharge, Bold Subscriptions, Checkout Champ rebill flows).
• Direct experience working alongside media buying teams, formal CRO methodology experience, and experience hiring or onboarding technical talent.

Benefits

• Lead conversion engineering for multiple growing consumer brands and see architecture decisions go live on high-traffic ecommerce sites.
• Performance bonus tied to funnel output quality and conversion improvements.
• Remote-first, results-focused team — measured on what you ship, not your hours.
• Paid leaves and allowances; opportunity to build and shape a team as it scales.

Additional Information

• Hiring process: submit portfolio (required), technical assessment (Checkout Champ + Shopify architecture task), final interview with leadership/team lead.
