Square has developed a growth framework for engineers and engineering managers, which includes a set of principles, frameworks, and processes to support professional growth. The framework is based on a career ladder with clear level definitions and expectations, and promotions are descriptive, not prescriptive, meaning that engineers and managers must demonstrate they are consistently performing at the next level before being promoted. The framework is designed to provide a roadmap for professional growth and to help engineers and managers understand what is expected of them. The company aims to balance maintaining consistent standards with the need to evolve and adapt to changing industry and business needs.
