Headquarters: New York City URL: https://sanctuary.computer We are hiring a contract-based Senior Shopify Developer to contribute to our Design and Development Team.

Original job posting link About garden3d We are worker owned creative collective, innovating on everything from brands and IRL communities to IoT devices and cross platform apps. We share profit, open source everything, spin out new businesses, and invest in exciting ideas through financial and/or in-kind contributions. Our client roster includes Google, Stripe, Figma, Hinge, Black Socialists in America, ACLU, Pratt, Parsons, Mozilla, The Nobel Prize, MIT, Gnosis, Etsy & Gagosian. We’re the software team behind innovative products like The Light Phone & Mill, and we operate a global, decentralized community space collective called Index Space. We think of our garden3d as collective for creative people, prioritizing a happy, talented, and diverse studio culture. We work on projects that bring value to our world, and we balance deep care for the work we do with a genuine curiosity about life outside of our jobs.

Sanctuary Computer — Development At Sanctuary Computer we’re building a different type of technology shop – one that prioritizes close collaboration between the client and the craftsperson. Our projects range from design-forward websites, to robust web apps, to native mobile development.

XXIX — Design When we started XXIX in 2013, we set out to create a different kind of design studio and we’ve thrived because we continually ask what a creative practice can be. We’re building a radically different kind of organization that values autonomy, growth, transparency, and shared responsibility. Plus, our partner organizations https://www.thelightphone.com/ https://www.mill.com/ https://www.ingredient-ai.com/

Who we’re looking for: We're looking for a Senior Shopify Developer who balances deep e-commerce expertise with modern frontend engineering. You'll build pixel-perfect, hyper-performant storefronts ranging from custom Liquid themes to headless Hydrogen/Next.js implementations working alongside our design team to create world‑class shopping experiences. In this role, you’ll work across a variety of client projects to find cost‑effective, high‑quality, and pragmatic solutions to complex e‑commerce challenges.

Responsibilities

• Collaborating closely with Technical Leads and Designers to meet clients' custom e-commerce and technical needs.
• Building and maintaining high-performance storefronts using both custom Liquid (Online Store 2.0) and modern headless architectures (Shopify Storefront API, GraphQL, Hydrogen/Remix, Next.js).
• Implementing responsive, accessible, and pixel‑perfect interfaces based on design specifications, with meticulous attention to product interaction details and motion design.
• Integrating custom storefronts with headless CMS platforms (Sanity, Contentful), payment gateways, subscriptions, search, and third‑party e‑commerce APIs.
• Optimizing e‑commerce performance, focusing heavily on Core Web Vitals, image/video asset delivery, bundle size, and runtime efficiency across high‑traffic collection and product pages.
• Architecting scalable, reusable component libraries and design systems tailored for commercial platforms.
• Writing clear documentation for store management, custom app integrations, and codebase maintenance.
• Participating in project team rituals, including Sprint Planning, daily standups, code reviews, and retrospectives.

The person we’re looking for is happy, relaxed and easy to get along with. They’re flexible on anything except conceits that will lower their usually outstanding work quality. They work “smart”, by carefully managing their workflow and staggering features that have dependencies intelligently. They prefer deep work but are OK coming up to the surface now and then for top level / strategic conversations. We believe people with backgrounds or interests in design, art, music, food or fashion tend to have a well rounded sense of design & quality, so a variety of hobbies or side projects is a big nice to have!
