Happy Mammoth is a fast-growing natural food tech business selling across the US, Australia, and Europe. We formulate, produce, and market gut, digestive, and microbiome health supplements — and performance marketing is a core growth driver for us.

- Build and refine creative testing roadmaps
- Brief and iterate with copywriters, editors, and designers

E-commerce Store Manager
12 abr.Happy Mammoth
E-commerce Store Manager
Happy Mammoth · Barcelona, ES
Teletrabajo . SEO
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) - You share ownership of Revenue per Visitor across all Happy Mammoth stores. Your contribution comes through the storefront experience itself: product page performance, checkout flow optimization, navigation, collections, and merchandising execution. You ensure that every deployment protects or improves on-site conversion. You own A/B testing on the storefront - checkout flow changes, PDP layout tests, navigation experiments to continuously improve the commercial performance of the store itself
- Store Improvement & Ecommerce Experience - You continuously improve the store experience across all three regions. This is not just maintenance - you identify friction points, UX gaps, and commercial opportunities within the storefront and direct your team to implement improvements that make the store easier to buy from. You think like a customer and lead like an operator. Every iteration should move conversion, AOV, or customer experience forward
- Brand & Design Consistency + SEO — You are the quality gate for brand and design alignment across all customer-facing digital properties. Every store, product page, collection, and marketplace listing must be visually and tonally consistent with the Happy Mammoth brand. You work closely with the designer to ensure that as content scales, brand quality does not degrade. You are also in charge of on-page and technical SEO across all stores - site structure, page speed, metadata, schema markup, and crawlability - directing internal teams or external specialists to ensure the storefronts are built to capture organic traffic, not just paid
- Compliance & Regulatory Control - You own the process of ensuring all stores, funnels, and Amazon listings are compliant. You work closely with the legal team to ensure that every page, claim, and piece of product content meets 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 nothing goes live without compliance sign-off. This means pre-launch review processes, post-launch audits, and fast resolution when issues surface. The target is zero compliance incidents that could have been caught
- 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 yours. You direct your developer to prevent performance degradation after updates or releases, and when issues arise, you diagnose the root cause and drive the resolution. If LCP spikes or checkout completion drops, you own the outcome
- Amazon Marketplace Performance - You manage the Amazon Marketplace Manager and own Amazon Conversion Rate vs category benchmarks. You ensure listing quality, compliance, and commercial performance across our Amazon presence
You have deep experience leading Shopify Plus store operations in a direct-to-consumer environment, not just configuring themes, but owning store architecture, checkout optimization, multi-store operations, and performance monitoring at scale through a team.
You have a strong eye for brand and design consistency. You can spot when a page, collection, or listing is off-brand and you know how to direct designers to fix it. You understand that brand quality and conversion are not at odds; they reinforce each other.
You understand SEO at a strategic level - site structure, metadata, schema markup, page speed optimization, and crawlability. You do not need to be an SEO specialist, but you need to know enough to set the right direction and manage internal teams or external agencies to deliver results.
You understand how compliance works in regulated industries. You do not need to be a regulatory expert, but you have experience coordinating with legal teams to ensure content is compliant across multiple markets. You know how to build and enforce review processes that prevent compliance issues, and you treat compliance as a system that protects revenue, not a checkbox.
You are technically sharp. You can read Core Web Vitals reports, diagnose checkout drop-off, and direct developers at a technical level to implement solutions. You are not just a project manager who files tickets, you understand the platform deeply enough to set the right direction.
You have experience overseeing A/B tests on storefront elements - checkout flows, PDP layouts, navigation, collections, and you know how to design tests that produce actionable results.
You manage the Amazon Marketplace Manager and direct a developer. You set the priorities, define the standards, and hold your team accountable for execution quality and speed.
You are methodical but fast. You build systems that prevent problems, but when fires happen, you move immediately. If you are someone who needs to be told what to prioritize, or who waits for instructions when something breaks, this is not the right role. We need someone who owns the store like it is their own business.
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
Most "store manager" roles are glorified admin positions - updating products, toggling discounts, keeping the site from breaking. This is not that. You are the operational and experiential backbone of a nine-figure global DTC brand. You own compliance across three regulatory jurisdictions. You own site performance across three storefronts. You own brand and design consistency across every customer-facing digital touchpoint. You own SEO. You own the Amazon marketplace. And you run A/B tests on the storefront to continuously improve the experience.
The decisions you make directly impact checkout completion rates, compliance risk, and site performance for millions of customer sessions. If you want a role where operational excellence is not just expected but directly tied to commercial results, this is it.
Practical Details
- Fully remote. GMT timezone preferred
- Competitive salary paid in USD
- Performance-driven culture — we reward results, not hours logged
- You will work inside a fast-moving global team of operators, not committees

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.

- 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
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.
