Senior Shopify Full Stack Developer

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

We're looking for someone who

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

Has built a shared theme or design system across multiple brands or storefronts (strongly preferred), and thinks in reusable infrastructure, not one-off builds

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

AWS or GCP, personalization frameworks, or additional performance monitoring experience is a plus

Approach to the role

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
