About the Role
We are looking for an experienced Signal Integrity and Power Integrity (SI/PI) Engineer to conduct simulation, analysis, and laboratory validation of high-speed digital interfaces across chip, package, and board levels. The role also involves technical customer support and collaboration with cross-functional engineering teams.
Key Responsibilities
Perform signal integrity analysis for high-speed interfaces, including HBM, DDR, LPDDR, UCIe, and MIPI.
Analyse crosstalk, reflections, impedance, eye diagrams, and transmission lines.
Conduct power delivery network (PDN) analysis, optimisation, and decoupling capacitor validation.
Perform PDN impedance measurements and correlate laboratory results with simulations.
Use SI/PI tools such as HyperLynx, Ansys SIwave, and Cadence Sigrity.
Conduct laboratory validation using TDR, VNA, and high-speed oscilloscopes.
Analyse S-parameters, Y/Z-parameters, and multi-port matrices.
Collaborate with chip, package, PCB design, and layout teams.
Support customers with board design reviews, technical queries, failure analysis, and root-cause debugging.
Key Requirements
Bachelor's or Master's degree in Electrical Engineering or a related discipline.
5–20 years of SI/PI experience, depending on seniority.
Strong hands-on experience in both SI/PI simulation and laboratory validation.
Experience with high-speed digital interfaces and relevant simulation tools.
Strong analytical, debugging, and problem-solving skills.
Good technical communication skills and confidence in customer-facing engagements.
