Federal job category 5400 includes trades focused on the operation of stationary and portable industrial equipment that powers, moves, or supports federal infrastructure and services. These roles involve running systems that generate electricity, steam, or compressed air; treat and distribute water; manage waste; and control mechanical structures like bridges, locks, and dams. Employees in this category may operate boilers, turbines, pumps, hoists, or floodgates—often coordinating multiple systems to maintain safe and efficient performance.

Most positions fall under the Federal Wage System and are hands-on, typically located at military installations, utility plants, or federal service facilities. Workers monitor gauges, adjust controls, and respond to alarms or system changes, often under time-sensitive conditions. Whether regulating steam flow in a heating plant or lifting equipment with industrial hoists, GS-5400 roles demand technical skill, situational awareness, and a strong commitment to operational reliability. These jobs are essential to keeping federal infrastructure powered, responsive, and mission-ready.
