About The Position

The Head of Development & Solutions — Shopify Specialist is a senior technical leader who combines deep Shopify expertise with strategic thinking and hands-on execution. This role sits at the intersection of architecture, delivery, and client engagement, responsible for ensuring our e-commerce solutions are technically exceptional, scalable, and directly aligned with client business objectives. This is not a purely managerial role. The ideal candidate thrives when moving between high-level architectural decisions and the technical nuances of Shopify platform implementation. They are equally comfortable presenting solutions to clients, mentoring developers, and reviewing code or API integrations.

From high-growth DTC brands to enterprise, we have partnered with companies such as: KITH, LVMH, TAG Heuer, Hugo Boss, Enjoy Life, Mondelez, Brandon Blackwood, Undefeated, Rumpl, HAUS, O'Neill, Serta Simmons Bedding, Badgley Mischka and many others. We design, build and optimize eCommerce experiences on Shopify Plus for global brands.

We ensure that our team members and partners possess these traits. We feel that it is important to prioritize these core values over everything else. This allows us to deliver results for our clients, as well as a safe and fun work environment.
