ABOUT AJ MEDIA
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 don't build for aesthetics — we build for conversion rate, average order value, and repeatability. Every line of code has a business outcome attached to it.
THE ROLE
This is the senior technical leadership role for our Checkout Champ and Shopify funnel stack. You'll own the architecture end-to-end — from spec to production deploy — across three growing consumer brands, with more launches planned. You'll lead all complex builds, mentor a junior developer, and have final say on QA and production releases. If you want to own outcomes rather than wait for direction, this is the seat.
WHAT YOU'LL OWN
Checkout Champ:
- End-to-end Checkout Champ funnel architecture and strategy
- Custom subscription flows and complex rebill logic
- Building and configuring 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 all brands
- Leading API integration work between platforms — from spec through deployment
- Resolving complex display/functional issues across storefronts
- Overseeing third-party app configuration and integration strategy
Tracking & Performance:
- Owning pixel and tracking architecture — Meta, Google, native platform events
- Diagnosing and resolving tracking discrepancies at the source
- Translating checkout flow changes into measurable conversion impact, working closely with media buying
Team Leadership:
- Directing and mentoring a Junior Checkout Champ Developer — assigning scoped tasks, reviewing work, and developing their path to ownership
- Setting technical standards, documentation practices, and code review processes
- Reviewing Checkout Champ and Shopify release notes and assessing impact across the stack
