The role of a product manager in a tech company is to act as a bridge between different teams, driving the product vision and strategy from conception to launch. They gather and prioritize customer feedback, collaborate with engineering, data analysis, design, and marketing teams, and ensure that the product meets user needs and business goals. Product managers also create roadmaps that outline the product's development and identify market trends. Their ability to balance technical, business, and user considerations is vital for delivering successful products.
