Senior Shopify Full Stack Developer

We're so happy you're here! Thank you for checking our job out and we hope to have the chance to meet you in our interview process!

About the role

------------------

Grüns operates multiple storefronts ranging from mature businesses to pre-launch start-ups. We need a Senior Shopify Full Stack Developer to own that Shopify architecture end to end, drive our AI-powered engineering workflows, and keep the technical bar high across a lean, high-impact team. This role has full ownership from architecture to deployment and will directly shape how fast Grüns can move for years to come. We are building a foundation that lets us launch new products, new storefronts, and new markets fast without rebuilding the wheel each time, while adjusting the site experience to each product's needs.

This role is part of our remote HQ!

We have a fully remote, high-trust work environment - and also come together on a bi-annual basis for amazing off-sites where we can connect IRL.

• 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 fulfi
