They are not coders. They are partners in success. Make sure first you treat them as such. Each person might have much to give above turning specs to code (ideas, processes, improvements, automations, design, architecture, etc...). If they feel they have a stake and their efforts are accommodated (and praised), there will naturally be an improvement.
