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 will include: 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! 🔑 Must-Have Competencies: We’re always pitching for new and exciting technology niches. Some of the areas below are relevant to us! 8+ years writing highly performant frontend code with an obsession for 95+ Lighthouse scores and optimal Core Web Vitals. Deep Shopify Ecosystem Mastery: Proven experience building custom Shopify themes (Liquid, JSON templates, Online Store 2.0) as well as headless storefronts using the Shopify Storefront API (GraphQL) and frameworks like Hydrogen/Remix or Next.js .
