How we counted: 256 open High-Speed IO/SerDes Design (Serdes Highspeed) roles from 53 employers tracked in the SemiconductorJobs index, counted 12 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 Analog & Mixed-Signal family row. Days are counted from when our index first saw each posting, not from the employer's original posting date.
