[Remote] Senior Shopify Full Stack Developer

Note: The job is a remote job and is open to candidates in USA. Grüns is a nutrition company operating multiple ecommerce storefronts and brands. The Senior Shopify Full Stack Developer will own Shopify architecture end to end, build scalable customer experiences and shared systems, lead AI-powered engineering workflows, and manage integrations, performance, reliability, and production launches.

Responsibilities

• Own the shared theme and design system architecture across all Grüns storefronts, built for scale across current and future brands
• Build best-in-class customer experiences: architect and ship major features (bundle builders, membership flows, new brand launches, international expansion) from design handoff to production
• Build AI-powered engineering workflows (Claude Code, Cursor, etc.) that make you faster, and that let non-engineers on the team do more themselves
• Design and implement scalable systems, shared components, and developer tooling that speed up CRO testing, new product launches, and brand rollouts
• Own site performance and reliability: enforce standards for site speed, SEO/GEO readiness, accessibility, and uptime, and use monitoring tools to catch issues before they're a problem
• Build and maintain integrations between Shopify Plus and backend systems like CRM, CDP, order management, and fulfillment
• Execute the nCAC and retention roadmaps in production, with full QA and rollout ownership
• Partner with Ecom, Growth, and Design to translate business priorities into technical milestones, estimate effort, and surface dependencies early
• Champion engineering quality with automated testing, CI/CD pipelines, and documentation that doesn't slow the team down
• Launch new brands and storefronts onto the shared architecture as Grüns expands

Skills

• Has 7-10 years of full stack development experience, including at least 4 years building Shopify themes and apps with Liquid and React
• Has a proven track record owning front-end and back-end Shopify builds end to end, from architecture to deployment, not just contributing pieces
• Uses AI coding tools daily as a core part of how they ship, not as an experiment
• Has deep command of Shopify Plus, Liquid, React/Next.js, Node.js, Tailwind, GraphQL and REST APIs, and modern CI/CD pipelines
• Has familiarity with headless commerce approaches
• Reaches for AI by default to move faster, and builds tools and workflows that raise the whole team's output, not just their own
• Highly autonomous. Can take a Figma file and partner with the designer to build it out without needing a fully spec'd user story
• Balances speed with scalability and communicates trade-offs clearly so the team can align on a pragmatic path forward
• Design-minded and customer-focused. Contributes ideas that improve experience, performance, and conversion, not just tickets to close
• Builds for reuse first, creating infrastructure and components that empower every brand, not just the one in front of them
• Communicates clearly across design, growth, and business stakeholders so everyone stays aligned
• Has built a shared theme or design system across multiple brands or storefronts (strongly preferred), and thinks in reusable infrastructure, not one-off builds
• AWS or GCP, personalization frameworks, or additional performance monitoring experience is a plus
