Job Description

It’s a perfect day to change the world! At Perfect Day, we’re doing just that. Perfect Day was founded in 2014 to create delicious, nutritious dairy products that everyone can love. We’re using fermentation (not animals) to make dairy proteins that are the foundation for foods like ice cream, cheese and yogurt – all with the distinctive taste and textures that consumers demand, but without lactose or environmental downsides. Through partnerships with respected brands, we’re working to launch a whole range of dairy products that will help shape a humane, sustainable food system for future generations.
