What does a Scrum Master do?
A scrum master helps oversee the scrum and development team. They are knowledgeable in Agile methodology and scrum and able to educate others. They also act as a buffer between the scrum team and product owner and maintain a safe working environment for the team by helping with conflict resolution.
To work as a scrum master, you need to hold some level of scrum master certification. Any experience working on a scrum team is beneficial, and the more experience the better. You will need to be able to think fast to help solve problems. Communication skills are a plus, as you will be communicating with the development and scrum teams and product owner. Leadership skills are a must as well.
