Job Description

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.
