A Product Manager sits at the intersection between technology, design, and business. Rather than having any official authority over people, they act as a leader by guiding teams towards a shared end goal.

Usually they will preside over one particular product, working with designers, engineers, marketing, and business analysts. They are essentially the glue that keeps the whole team working together. They also communicate with stakeholders, own the product vision, have a deep understanding of their customers, and create the product roadmap.
