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.

Responsibilities

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

Merchandise & 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

What Success Looks Like at 90 Days

• 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
• Bundle 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

Who Will Thrive Here

• You're a marketer first who happens to be dangerous in the theme — you'd rather ship the page yourself than wait in an engineering queue
• You ship to learn. A live page today beats a perfect one next week — you ship the test, read the margin, and kill your own darling when the data says so
• You own the number, not the task. When inventory shows in-stock but isn't, you own the fix and the post-mortem — you don't punt to engineering or NetSuite
• You're AI-native — AI is a default multiplier on automations, theme work, and reporting
• You raise the flag early. We hear about a slipping launch or wrong inventory from you first, before we ask
• You're comfortable with a daily standup and a Monday traction meeting — high-touch, fast-feedback management, not weekly check-in autonomy
• Low ego, high standards. Your calls get redlined; you take it and push back when the data supports it

Requirements

• 2+ years hands-on Shopify in DTC ecommerce — including working admin (products, variants, metafields, collections, navigation, discounts, markets, shipping rules)
• Numerate: reads Shopify analytics + GA + Triple Whale (or similar) and computes contribution margin from order data
• Hands-on with A/B testing — runs tests with a hypothesis and a kill criterion (Visually or similar)
• Hands-on in the theme: customise sections, edit Liquid, and use AI tooling to adjust HTML/CSS/JS to get a page live, QA'd mobile + desktop, logged-in + out (≈4/10 technical depth — you build, you're not an engineer)
• Strong project management — owns launch timelines end-to-end (Asana or similar)
• AI-native — defaults to AI tooling for automation, theme work, and reporting
• Startup or lean-team experience

Helpful but not required:

• DTC fitness / equipment or subscription-app experience
• Hands-on with subscription tools (Recharge or similar)
• International / multi-market Shopify (Markets, distributor models)
• NetSuite
