About The Position

Carl Zeiss X-ray Microscopy is seeking a Cleanroom Manufacturing Technician to build precision ultra-high-vacuum components and subassemblies used in advanced X-ray source production. The role involves assembling, inspecting, testing, troubleshooting, and improving high-precision vacuum, mechanical, and electromechanical assemblies while following controlled procedures and cleanroom protocols. The position reports to the Production Line Manager and is based in Dublin, California, primarily in a Class 10K cleanroom and adjacent production and test areas. The position is assigned to swing shift. For the first three months, the schedule is Monday through Friday, 7:00 a.m. to 3:30 p.m.; it then transitions to Monday through Friday, 1:30 p.m. to 10:00 p.m. The annual pay range is $31.73 to $39.42.
