Signal and Power Integrity Engineer

About the Role

Renesas is seeking a highly skilled Signal and Power Integrity Engineer to support the design, analysis, and validation of high-speed package and board designs. The ideal candidate will have strong fundamentals in electromagnetics and high-speed signalling, hands-on experience with industry-standard simulation tools, and an ability to collaborate across silicon and systems teams to deliver robust, manufacturable products.

Key Responsibilities

• Perform signal integrity (SI) and power integrity (PI) analysis for high-speed package, PCB and system level designs.
• Conduct 2D and 3D EM simulations to evaluate interconnect performance to mitigate crosstalk, impedance, and loss.
• Analyse and optimize power distribution networks (PDN) including power plane design, decoupling strategies, and IR drop analysis.
• Execute frequency-domain and time-domain simulations for high-speed interfaces.
• Perform channel simulations and system-level analysis using tools such as ADS and HSpice.
• Support design reviews, layout guidance, and ECO cycles with SI/PI recommendations.
• Work with validation teams to correlate simulation results with lab measurements and debug signal and power integrity issues.
• Develop and maintain technical documentation, reports, and presentations.
• Collaborate closely with PCB layout, hardware, packaging, and validation teams.

Requirements & Tech Stack

• Strong fundamentals in electromagnetics, transmission lines, and microwave theory.
• Hands-on experience with EM simulation tools such as: ANSYS HFSS, SI-Wave, Cadence Power-SI.
• Experience with circuit analysis and simulation tools: ADS, HSpice.
• Proficiency in handling and analysing IBIS/Spice models.
• Experience in power plane modelling and analysis using tools such as Power-SI, Power DC or SI-wave.
• Working knowledge of package and PCB technologies including stack-up analysis, DFM, material behaviour etc.
• Solid understanding of high-speed signalling in both time and frequency domains.
• Nice to have: hands-on experience with lab measurement equipment including VNA, oscilloscopes, TDR and spectrum analysers.
• Experience in test case development and automation using scripting languages (Python, MATLAB, or similar).
• Strong communication, presentation, and documentation skills with the ability to work effectively in a team environment.
