A back-office manager is responsible for work performed by back-office employees. The back-office manager often supervises other back-office employees in entry-level to mid-level positions. While the professional background for back-office managers can be any relevant course, they are mostly sourced from engineering, business management, accounting, or mathematics fields. Back-office managers are usually excellent communicators, thanks to the nature of their work.
A back-office manager's resume for a professional with 10+ years of experience should focus on the impact of their work. This means demonstrating the effect of your actions on, say, a company's bottom line, departmental efficiency, etc. This helps the hiring manager assess the value you will add to their company if they hire you.
