About Mammoth Fieldhouse

Mammoth Fieldhouse OKC is a competitive social venue where sport, food, and community share one roof. Pure Putt. Arc Rivals. Battle Bats. Wiffle Ball. A self-pour beer wall, a scratch kitchen, and a full bar built to stand on their own. Open play, leagues, tournaments, and private events, all night, every night.

Oklahoma City is a big-league sports town with no shortage of places to spend a night out. Athletes here have options, which means the standard has to hold on a slow Wednesday and a sold-out Saturday alike.

About the Role

You are the operating system behind the building.

The Office Manager keeps the administrative side of a large, fast venue accurate and on time: payroll, onboarding, records, cash controls, vendor accounts, and the paperwork that has to be right the first time.

This role touches every teammate in the building. You are the first administrative face a new hire meets and the person who makes sure their first paycheck is correct.

Discretion matters here. You will handle sensitive personnel and financial information every day.
