How we counted: 161 open Silicon Test Engineering (Silicon Validation) roles from 55 employers tracked in the SemiconductorJobs index, counted 13 Nov 2026. Specialty figures count only roles carrying this exact specialty label, so an employer's related work in neighbouring specialties is not included there, and is counted in the wider Silicon Validation & Test family row. Days are counted from when our index first saw each posting, not from the employer's original posting date.
