HarZa Group builds and scales direct-to-consumer health and wellness brands. Our flagship brand is Rejuvacare, with RejuvaKnee as our hero product in chronic pain relief, and we are actively launching new brands across the portfolio. We run entirely on paid digital channels, ship primarily into the United States, and have grown twelve times in a single year with close to 150 people across more than 15 countries. We are remote-first by design and async-first by default.
The Role
In this business, an idea only starts producing revenue once it is live as a working page, funnel or checkout. Marketing can develop a concept and write the copy in a day. How fast that becomes a live, accurate and fully functioning funnel is what determines how fast the company moves.
Checkout Champ is where that happens. We are hiring a Checkout Champ Funnel Developer to build and maintain the funnels that carry our revenue: advertorials, landing pages, VSL pages, quizzes, product pages, checkouts, upsells, downsells and post-purchase flows.
We ship daily, not monthly. If you enjoy the rhythm of building,



launching, testing and iterating inside the same week, this will suit you. If you need long release cycles and a fully specified ticket for every task, it will not.
What You'll Do
- Build and maintain DTC funnels end to end in Checkout Champ.
- Turn Figma designs, approved copy and assets into responsive, production-ready pages.
- Build quizzes, selectors, dynamic flows and other interactive funnel experiences.
- Configure offers, order forms, checkout flows, upsells, downsells and post-purchase journeys inside Checkout Champ.
- Implement and troubleshoot tracking, pixels, events, GTM, scripts and conversion-related integrations.
- Work with APIs, webhooks and third-party tools where a requirement calls for it.
- Build and launch A/B test variations.
- Troubleshoot front-end, checkout, funnel logic, integration and tracking issues on live traffic.
- Create reusable components and templates
