Growth Marketing Manager (CRO & Ecommerce Optimization)

The Opportunity

Happy Mammoth is looking for a Team Lead, E-commerce to own the entire digital commercial engine across our Shopify Plus stores (US, EU, AU) and Amazon marketplace. This is not a "manage the website" role. You will be directly responsible for on-site revenue performance, funnel development, compliance governance, and technical stability across every revenue-generating digital property we operate.

About Happy Mammoth

Happy Mammoth is a fast-growing natural health company formulating, producing, and marketing gut health and hormone-balancing supplements to millions of customers across Australia, the United States, and Europe. We operate direct-to-consumer through Shopify Plus and Amazon, with deep roots in performance marketing and direct response. This is a company built on speed, testing, and commercial results.

The Role

You will lead the e-commerce function and own six critical outcome areas:

• Conversion & Commercial Execution - You own on-site commercial performance across all Happy Mammoth stores and the Amazon marketplace. Your job is to protect and grow Revenue per Visitor and marketplace conversion rates.
• Funnel & Page Development System - You own the creation, deployment, and optimization of funnels, landing pages, PDPs, and commercial flows. You set the direction, brief designers and developers, and drive the cycle time from approved brief to live deployment down while keeping quality high. You define and oversee structured A/B testing, ensure performance validation before scaling, and monitor post-launch impact. Every new page or funnel should either prove a hypothesis or improve a metric.
• Product Launches & Special Campaigns - You lead the commercial execution of new product launches and seasonal or promotional campaigns. You direct designers and developers to build the launch funnels, landing pages, and supporting assets, set the creative direction, coordinate timing with the paid media team, and ensure every launch is set up for measurable success from day one.
• Brand & Design Consistency + SEO - You are the quality gate for brand and design alignment across all customer-facing digital properties. Every store, funnel, product page, and marketplace listing must be visually and tonally consistent. You also own on-page and technical SEO across all stores - site structure, metadata, schema markup, and crawlability - ensuring storefronts capture organic traffic, not just paid.
• Compliance & Regulatory Control - You own the process of ensuring all stores, funnels, and marketplace listings are compliant. You work closely with the legal team to ensure that pages, claims, and product content meet regional regulatory requirements across all markets before and after launch. You do not need to be a regulatory expert, but you need to build and enforce the systems that ensure compliance is checked, maintained, and never an afterthought. Zero tolerance for post-launch compliance fires that could have been prevented
• Store Stability & Technical Performance - You own functional reliability and operational excellence across all digital properties. Site speed, checkout performance, tracking integrity, and platform stability are your responsibility. You direct your development team to prevent performance degradation after updates or releases. If the checkout breaks or load times spike, you own the resolution - diagnosing the issue, directing the fix, and ensuring it does not happen again

What We’re Looking For

You have senior-level experience running e-commerce operations in a direct-to-consumer environment, ideally in health, supplements, or a similarly regulated vertical. You understand Shopify Plus deeply, not just as a user but as someone who has overseen store architecture, checkout optimization, and multi-store operations at scale.

You are fluent in funnel metrics: CVR, AOV, RPV, LTV, and CAC are part of your daily vocabulary. You have directed the creation and optimization of landing pages, PDPs, and commercial funnels, and you have overseen structured A/B testing programs with measurable results.

You understand how compliance works in regulated industries. You do not need to be a regulatory expert, but you have experience working with legal teams to ensure content is compliant, and you know how to build systems that prevent compliance issues from slipping through.

You are technically sharp. You can read site speed reports, diagnose checkout issues, and direct developers to fix problems - not just file tickets and wait.

You move fast, make decisions with imperfect information, and take full ownership of outcomes. You set direction for your team and hold them accountable for execution. You do not need to be told what to do. You see the problem, diagnose it, and mobilize the right people to fix it.

This is a hands-on role. You are expected to be directly involved in execution — not just defining strategy, but driving implementation and results.

Your team

You will lead a cross-functional team of developers and marketplace specialists, with additional support from design, copy, and project management. You report directly to the Head of Growth.
