Job Description

The Opportunity

Happy Mammoth is looking for an E-commerce Store Manager to own the operational backbone of our Shopify Plus stores (US, EU, AU) and Amazon marketplace. You will be responsible for store stability, compliance governance, technical performance, and the core storefront experience that millions of customers interact with every month.

This is the role for someone who believes that a flawless store experience is not a given – it is engineered. If broken checkouts, slow load times, and compliance gaps keep you up at night, we should talk.

This is a hands-on role where you will be expected to execute and implement, not just manage.

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 five critical outcome areas:

Conversion & Commercial Execution (Shared) – Share ownership of Revenue per Visitor across all Happy Mammoth stores. Your contribution comes through the storefront experience: product page performance, checkout flow optimization, navigation, collections, and merchandising execution. Ensure every deployment protects or improves on-site conversion and own A/B testing on the storefront.
Store Improvement & Ecommerce Experience – Continuously improve the store experience across all three regions. Identify friction points, UX gaps, and commercial opportunities, directing your team to implement improvements that enhance the buying process.
Brand & Design Consistency + SEO – Ensure brand and design alignment across all customer-facing digital properties. Work with the designer to maintain brand quality as content scales and manage on-page and technical SEO across all stores.
Compliance & Regulatory Control – Ensure all stores, funnels, and Amazon listings are compliant. Work with the legal team to meet regional regulatory requirements before and after launch.
Store Stability & Technical Performance – Manage functional reliability and operational excellence across all digital properties. Direct your developer to prevent performance degradation and resolve issues swiftly.
Amazon Marketplace Performance – Manage the Amazon Marketplace Manager and own Amazon Conversion Rate vs category benchmarks.

Who We’re Looking For

You have deep experience leading Shopify Plus store operations in a direct-to-consumer environment.
You have a strong eye for brand and design consistency, understanding that brand quality and conversion reinforce each other.
You understand SEO at a strategic level and can manage teams or agencies to deliver results.
You understand compliance in regulated industries and know how to build review processes that prevent issues.
You are technically sharp and can diagnose technical issues and direct developers to implement solutions.
You have experience overseeing A/B tests on storefront elements.
You manage the Amazon Marketplace Manager and direct a developer, setting priorities and holding your team accountable.
You are methodical but fast, able to build systems that prevent problems while responding immediately when issues arise.

Your Team

You will have a dedicated developer and a marketplace specialist on your team, with additional support from design and project management. You report to the Head of Growth.

Nice to Have

Experience in DTC brands
Familiarity with CRO and analytics tools
Experience managing Shopify Plus stores across multiple regions
Experience working with SEO agencies or specialists
Familiarity with Amazon marketplace management

Why This Role Is Different

You will be the operational and experiential backbone of a nine-figure global DTC brand. You own compliance across three regulatory jurisdictions, site performance, brand consistency, SEO, and A/B tests to continuously improve the experience.

Your decisions will significantly impact checkout completion rates, compliance risk, and site performance for millions of customer sessions.
