Strong problem-solving abilities, quick decision-making, and effective communication are vital soft skills for responding to urgent production incidents. These capabilities are crucial to rapidly diagnose, address, and prevent system-level failures, ensuring system stability and uptime.

Can you be on call as a software engineer?
