About The Position

This is a temporary seasonal Maintenance Mechanic position with the Seasonal Staffing Office at Yosemite National Park. The typical seasonal entry-on-duty period is April through May, but timing may vary due to weather, project needs, or funding. The appointment is expected to end when the season’s work is complete and generally may not exceed 1,039 hours; depending on the park and program, it may instead be not-to-exceed 1,560 hours. Employment may end earlier because of funding, project needs, performance, or other considerations.
