Job summary

GrowthAssistant, a fully remote team, is hiring a Senior Shopify App Developer to own custom checkout and customer-login integrations on Shopify Plus for a healthcare e-commerce company. You will lead independent development with room to grow into technical lead as the Shopify team scales to 3–4 developers and support multi-partner storefronts from one backend.

You bring 5+ years in Shopify development, hands-on checkout experience, strong TypeScript/Node.js skills, and experience with identity

Qualifications

• 5+ years of Shopify development with a shipped custom app on Shopify Plus.
• Hands-on custom checkout experience: Checkout Extensions, Payments Apps API, or a payment-provider integration (Stripe preferred).
• Strong TypeScript/Node.js, and experience integrating a third-party identity provider (OpenID Connect, Azure B2C, or similar).
• Independent judgment to read unfamiliar codebase, estimate honestly, and make architectural calls without a tech lead.
• Daily use of AI coding tools (Claude, Cursor, Copilot) with US Eastern Time overlap.

Responsibilities

• Own the custom checkout build, keeping Stripe/IIAS flow inside Shopify so e-commerce purchases auto-substantiate.
• Integrate third-party identity provider with Shopify customer accounts via the client's auth hub.
• Scope and sequence integration workstreams (login, eligibility engine, checkout), then maintain integrations.
• Build and maintain custom Shopify apps on Admin, Storefront, Customer Account, and Checkout/Payments APIs.
• Read and document decisions so the business team can ship routine changes independently.
