Full-Time | South Korea | Engineering

Job Purpose

As a off-chip PSI (power signal integrity) engineer, this person will be responsible for defining off-chip PSI spec to meet product requirement, modelling a device for off-chip PSI analysis, setting up off-chip PSI analysis environment, running off-chip PSI analysis, analysing off-chip PSI results, providing guidelines to package & hardware engineers to improve package & hardware design, and signing off the final off-chip PSI analysis results.

Principal Accountabilities

▪ Define the target spec of off-chip PSI to meet product and/or standard requirements
▪ Model the high speed signals and high power lines from package design and hardware (evaluation board) design
▪ Set up the off-chip PSI analysis environment while connecting all extracted models
▪ Run the off-chip PSI analysis using related EDA tools for off-chip PSI analysis
▪ Analyse the off-chip PSI analysis results and confirm whether they are spec in or not
▪ Provide guidelines/feedback to package & hardware engineers to improve package & hardware design
▪ Sign off the final PSI analysis results and call to go for manufacturing

Key Performance Measures

▪ Define off-chip PSI spec and produce off-chip PSI analysis results
▪ Provide guidelines/feedback to improve package & hardware design
▪ Final products (package & hardware) work well while meeting the spec & requirements


▪ Experience as an off-chip PSI engineer for minimum 6 years (plus point: 12+ years)
▪ Knowledge and technical background in SI (signal integrity) and PI (power integrity) analysis
▪ Experience in running off-chip PSI EDA tools such as 1) Ansys: Siwave, HFSS, 3DLayout, 2) Cadence: Clarity, PowerSI, 3) Keysight: ADS)
▪ Knowledge & experience for high speed signals (DDR/LPDDR/GDDR, PCIe, MIPI, HDMI, etc)
▪ Cooperative attitude/manner to collaborate with related teams & engineers
