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.
