Join Our Team

The Sonoma County Public Infrastructure (SoCoPi) Department leads the way to a safe and sustainable community by planning, building, managing, and maintaining Sonoma County's investment in quality services and infrastructure. SoCoPi operates and maintains various facilities across the County, many of which were constructed during the 1950s and 60s and require consistent upkeep and care. The locations include the Airport Complex, County Administration Center, Chanate and Los Guilicos Campuses, Main Adult Detention Facility, and four Veterans' Memorial Buildings.

Please note that the construction and maintenance responsibilities of the Building Mechanic positions require sitting, standing, reaching, kneeling, bending, stooping, crawling, squatting, crouching, grasping, and walking on level, sloped, and slippery surfaces at various heights. They also require the need to lift, carry, and push equipment, materials, and supplies weighing up to 100 pounds. Incumbents are required to work in all weather conditions, including rain, cold, heat, fumes, dust, and other air contaminants which may cause eye and skin irritation. The nature of the work also requires incumbents to handle noise-producing tools and equipment, refrigerants and solvents, and drive County vehicles. Possession of a valid class C or higher driver's license is required for this position because the position's typical duties include fieldwork that requires driving County vehicles.

Additionally, this position is required to have access to Sheriff's Office and/or Probation Department facilities and/or view data or work with information systems for these departments. This requires that a more extensive "Security Clearance" will be performed after hire. Successful completion of the probationary period will be contingent upon passing the security clearance, which includes a Live Scan fingerprint-based check of the California Department of Justice (DOJ) and Federal Bureau of Investigations (FBI) criminal records. If you are offered a position that requires a security clearance, the job offer letter will clearly specify this as a condition of the probationary period.

This recruitment is being conducted to fill a Building Mechanic position at either the I or II level in SoCoPi, formally the General Services Department. This employment list may also be used to fill future full-time, part-time, or extra-help (temporary) positions as they occur during the active status of the list. Qualified County employees who wish to be considered for future positions should consider applying to this recruitment.
