Ecommerce Growth Specialist
About the role
Centr is seeking an E-Commerce Growth Specialist — a growth marketer who can build — to turn audiences into profitable equipment and app buyers across shop.centr.com, inspirefitness.com, and our international storefronts. This is a marketer-who-can-build role. A pure developer will fail here — and so will a marketer who can't get hands-on in the theme. You're driven by the offer and the number, but you're comfortable customising themes and editing Liquid sections.
You'll design, build, and ship net-new offer tests end-to-end fast, read against a margin hurdle, losers killed quickly, winners rolled across the storefront.
Equally, you own the day-to-day that drives most of today's revenue: product launches, promo theme swaps, and homepage/PLP/PDP merchandising — shipped clean and on time.
You own outcomes, not task completion. Expect roughly 70% hands-on building and shipping and 30% reading results and deciding what to scale.
Find & Prove Scalable Offers
- Ship net-new offer tests end-to-end — offer, landing page, product — each with a hypothesis, success metric, and kill criterion
- Build net-new landing pages for paid media, brief to live
- Judge each test on first-order contribution margin, CAC, and AOV; kill weak offers fast; double down only where the numbers show scale
- Run A/B tests via Visually; optimize for conversion, add-to-cart, attach rate
Launch & Promote
- Ship 100% of product launches on time and defect-free — copy, imagery, pricing, variants, metafields, inventory, collection and nav placement
- Run promo launches and theme swaps — built clean, scheduled, QA'd
- Sell equipment buyers on the Centr App subscription through bundles, cross-sells, and upsells across PDP, cart, and post-purchase
- Partner with the creative team to turn audience-offer insight into pages and assets that convert
- Ship theme changes and A/B variants cleanly, QA'd before production
Mercandise & Operate
- Implement merchandising and customer-journey improvements across the store
- Build and operate cross-sell, upsell, and subscription opportunities for physical goods through Recharge
- Keep track of inventory vs consumption run-rates to minimize stock outages
- Operate the international storefronts — currency, shipping rules, distributor onboarding, reporting
- Read Shopify analytics + GA + Triple Whale; know when a test has the volume to call
- Offer tests shipped and read — each with a hypothesis, a margin read-out, and a clear kill-or-scale call
- Launches shipped end-to-end, independently
- Bundling and Centr App subscription cross-sells live and being tested
- Inventory levels managed with potential stock outages flagged well in advance
- Bringing your own audience, offer, and merchandising recommendations to the table
Low ego, high standards
- Your calls get redlined; you take it and push back when the data supports it
