About the role

Centr is seeking a Shopify Growth Specialist to find what scales – building and shipping the audience-offer tests, and the storefront behind them, that turn audiences into profitable equipment and app buyers across shop.centr.com, inspirefitness.com, and our international storefronts.

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
• Judge each test on first-order contribution margin, CAC, and AOV; kill weak offers fast; double down only where the numbers show scale

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
• Build paid and campaign landing pages from brief to live
• Sell equipment buyers on the Centr App subscription through bundles, cross-sells, and upsells across PDP, cart, and post-purchase
• Ship theme changes and A/B variants through GitHub

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
• Run A/B tests via Visually; optimize for conversion, add-to-cart, attach rate
• 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
• 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

• 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

• Finding an offer that scales is genuinely hard. Most tests won't win. It takes real understanding of audience-offer fit and the ability to translate it into product spec, creative, framing, and offer construction — you need the judgment to spot a winning offer and the craft to build one
• You own multiple storefronts (shop.centr.com, inspirefitness.com, and international) with different catalogs and contexts
• A lot of the day-to-day is unglamorous hygiene — QA checklists, merchandising-queue grind, catalog and inventory wiring.

• 2–4+ years hands-on Shopify in DTC ecommerce
• Deep Shopify admin: products, variants, metafields, collections, navigation, discounts, markets, shipping rules
• Liquid, HTML, CSS, JS: can create new sections, edit existing theme code, and launch new themes
• Ships through GitHub — create, review, merge PRs; QA theme code before production
• Numerate: reads Shopify analytics + GA + Triple Whale (or similar) and computes contribution margin from order data
• Strong project management — owns launch timelines end-to-end (Asana or similar)
• AI-native — defaults to AI tooling for automation, theme development, and reporting
• QA discipline by default — mobile + desktop, logged-in + logged-out
• DTC fitness / equipment or subscription-app experience
• Hands-on with A/B testing tools (Visually or similar)
• Hands-on experience with subscription tools (Recharge or similar)
• Startup or lean-team experience

Helpful but not required:

• International / multi-market Shopify (Markets, distributor models)
• NetSuite
