Experience with product recommendation engines, personalisation tools or similar Shopify technology. Previous experience supporting multi-store Shopify environments. Contract & Logistics Part-time contract role – approximately 20 hours per week. Engaged through Assist World . You will work alongside a full-time Shopify Manager responsible for day-to-day Shopify operations. Must be available during PST business hours for communication and collaboration with the team. Compensation will be confirmed based on the client's available monthly budget. Who We're Looking For We're looking for someone who can step into an existing Shopify environment and hit the ground running . You should be comfortable troubleshooting technical issues, working with existing code and integrations, and finding practical solutions without needing constant direction. If you're an experienced Shopify Plus developer who enjoys working independently and taking ownership of the technical side of an established e-commerce environment, we'd love to hear from you.
