Technical SEO Specialist (Contractor)
Meet Domaine , the world's largest independent Shopify design and development partner, formed by the union of Half Helix and Tomorrow. We are a team of commerce experts dedicated to creating, building, and growing beloved brands. As pioneers and not just participants in our industry, we are inspired to write, break, and re-write the rules for a new generation of commerce.
We're seeking a Technical SEO Specialist to support and scale Domaine 's SEO practice. This role reports directly to the SEO Director and works closely with Strategy, Engineering, Design, and Content teams. This is a contract role with a minimum commitment of 20 hours per week to start, with the opportunity to scale hours based on business and client needs.
This role is hands-on technical. You'll work with both on on-page technical work and replatforming and migration projects — from pre-migration audits and URL mapping through redirect strategy, post-launch QA, and performance recovery. While strong fundamentals across on-page SEO and content strategy are expected, the primary emphasis is on technical SEO execution and protecting (or accelerating) organic performance through change.
