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.

• Collaborating closely with Technical Leads and Designers to meet clients' custom e-commerce and technical needs.

• 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.

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! 🔑Â
