A technical product manager is a product manager who focuses on the technical aspects of a product, such as deciding on the tech stack and architecture plans. They act as a liaison between the engineering and product teams, providing valuable expertise in both strategy and development. Technical product managers have a strong technical background, often starting as computer science graduates or developers, and bridge the gap between the product and development teams. Their role involves defining success criteria for testing and quality assurance, communicating with the technical community, and assessing risks and opportunities in bringing new technologies into the company. They translate business goals to technical requirements and assess what's technologically feasible, making them essential for tech companies with a focus on product development.
