A senior engineer recognizes the importance of the team, and they identify and complete tasks that benefit the team, even if the work isn’t planned or assigned to them. They understand that sometimes being senior means taking on the mundane tasks that no one else wants to do, because it will help unblock others to complete more work. Their focus is always a team-first approach, and they strive to lift up all members of their team because they know that when it comes to software, we all share the same responsibility to keep the systems running and deliver as much value to our users as possible.
