About the role
As a Senior Process Engineer, you will develop, optimize, and sustain semiconductor test processes to ensure high yield, reliability, and cost-effective production.
What you'll do
- Develop, qualify, and release test processes for new products (NPI to Production transition).
- Monitor daily test yield performance and identify yield loss drivers.
- Investigate abnormal test trends (e.g., IDSS shifts, leakage, parametric drift).
- Support test program development and debug on ATE platforms (e.g., Advantest, Teradyne).
- Implement and maintain SPC controls (UCL/LCL, Cpk, Ppk) for critical parameters.
- Drive test cost reduction initiatives (test time, multisite optimization, program efficiency).
- Prepare technical reports, yield summaries, and management updates.
What you'll need
- Bachelor’s or Master’s degree in Electrical Engineering, Electronics Engineering, Semiconductor Engineering or related field.
- 2–5+ years in semiconductor test/process engineering.
Nice to have
- Experience in Assembly & Test (back-end) environment.
Skills: test processes, yield improvement, ATE platforms, test programs, characterization

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.
