Requirements

WHO WE ACTUALLY NEED (and who we don't)

This is not for someone who:

• Wants a side hustle or is juggling multiple freelance jobs.
  
• Needs constant supervision or step-by-step instructions to get things done.
  
• Struggles with changing priorities or working in a fast-paced environment.
  
• Prefers doing things the way they've always been done rather than finding better ways to work.
  
• Has only worked with drag-and-drop page builders or no-code tools and has not written production code.
  

This is however for someone who:

• Works with Git day to day (branches, pull requests, code review) and knows how to test and deploy website changes safely.
  
• Has strong, hands-on Shopify experience, including theme management, app integrations, troubleshooting, and website optimization.
  
• Has practical experience with website tracking, analytics, CRO, and improving conversion rates.
  
• Can manage multiple storefronts while maintaining consistency, performance, and accessibility.
  
• Works effectively with developers, designers, agencies, and other teams to get things done.
  
• Is exceptionally detail-oriented, analytical, and naturally curious - you notice things others miss and enjoy figuring out why something isn't working.
  
• Takes ownership, solves problems proactively, and follows through without needing constant direction.
  
• Communicates clearly, asks the right questions, and keeps others informed.
  
• Is adaptable and resourceful, comfortable managing changing priorities and finding solutions to unfamiliar challenges.
  
• Embraces AI, automation, and better systems to simplify work and improve efficiency.
  
• Is dependable, takes pride in their work, and holds themselves to high standards.
