## Description

**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

## Requirements

**WHO YOU ARE**

-   4+ years of 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 move CRO/AOV metrics
-   Experience mentoring or leading junior developers
-   Excellent written communication — async-first, remote team, clarity is non-negotiable

**PORTFOLIO REQUIREMENT**

Portfolio is mandatory. Applications without Checkout Champ and Shopify project examples will not be reviewed. We're looking for:

-   Multiple Checkout Champ funnels you've architected end-to-end — screenshots, Loom walkthroughs, or live links
-   Shopify projects demonstrating advanced theme/Liquid work
-   Examples of API integrations you've led from spec to deployment

**STRONG PLUS**

-   Experience with post-purchase upsell apps
-   Deep familiarity with subscription platforms
-   Direct experience working alongside media buying teams
-   Formal CRO methodology experience
-   Experience hiring or onboarding technical talent

**HIRING PROCESS**

-   Submit portfolio (required — no exceptions)
-   Technical assessment (Checkout Champ)
-   Final interview with leadership/team lead
