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.

Job description

GrowthAssistant connects top marketing and operations talent with fast-growing companies that depend on great execution to scale. Founded in 2021 and named by Forbes as one of the best startups to work at, we're a permanently remote team that runs on integrity, proactive candor, and a bias toward action — and we prioritize the human experience in everything we do. We hire for skill and for heart, and we invest in our people for the long haul.

The Opportunity

We're hiring a Senior Shopify App Developer for a healthcare e-commerce company — owning custom checkout and customer-login integrations on Shopify Plus and building the custom apps behind them. This is a senior, independent role with room to grow into technical lead as the Shopify team scales to 3–4 developers, and to lead a white-label build that powers multiple partner-branded storefronts from one fulfillment backend.

What Your Day-to-Day Will Look Like

• Custom Checkout: Own the custom checkout build, keeping the existing Stripe and IIAS flow inside Shopify so FSA/HSA purchases auto-substantiate with no receipts.
• Customer Login: Integrate a third-party identity provider with Shopify customer accounts through the client's existing auth hub (Azure B2C / OpenID Connect).
• Integration Planning: Scope and sequence the integration workstreams (login, eligibility engine, checkout), then maintain the integrations on a continuous basis.
• Custom Shopify Apps: Build and maintain custom Shopify apps on the Admin, Storefront, Customer Account, and Checkout/Payments APIs.
• Code & Documentation: Read and extend the client's existing TypeScript code, and document decisions so the business team can ship routine changes independently.

What You Bring

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

Bonus Points if:

• You have HSA/FSA, healthcare e-commerce, or IIAS-certified checkout experience.
• You have migrated from a headless or custom stack (e.g., commercetools, Hydrogen) to standard Shopify.
• You are familiar with Azure B2C or Shopify data-layer and analytics integration.
