👉 Calling engineering, also known as system-level or integration engineering, is a specialized discipline that focuses on the design, development, and integration of complex systems, particularly in software engineering. It involves ensuring that various components, subsystems, and external interfaces work seamlessly together to achieve the desired functionality of a larger system. This includes tasks such as architecture design, interface specification, component integration, testing, and validation at the system level. Calling engineers bridge the gap between different layers of a system, from low-level hardware and software components to high-level business processes, ensuring that the final product meets all functional, performance, and reliability requirements. Their expertise is crucial in large-scale projects where multiple teams and technologies must collaborate effectively to deliver robust and scalable solutions.
