Your Team, Your Impact

What You Can Expect

We are seeking an experienced Signal Integrity / Power Integrity (SI/PI) Engineer to drive the design, analysis, and validation of highspeed electronic systems. The successful candidate will play a critical role in ensuring robust signal and power performance across silicon, package, PCB, and system levels for nextgeneration products.
In this role, you will partner closely with architecture, silicon, package, board design, validation, and manufacturing teams to influence hardware decisions, identify risks early in the design cycle, and ensure compliance with performance, reliability, and interoperability requirements.

Key Responsibilities:
* Lead SI and PI analysis for highspeed digital interfaces, from early architecture definition through postsilicon validation and production enablement.
* Perform prelayout and postlayout signal integrity analysis, including channel modeling, eyediagram analysis, jitter decomposition, timing margin analysis, and compliance assessments.
* Design and analyze power distribution networks (PDN) across die, package, and PCB, including AC impedance analysis, transient simulations, decoupling strategies, and noise mitigation.
* Support and optimize highspeed interfaces such as DDR4/DDR5, HBM, PCIe Gen4/Gen5/Gen6, Ethernet (NRZ and PAM4), and other SerDesbased links.
* Develop and enforce SI/PI guidelines, methodologies, and signoff criteria to ensure consistent design quality across multiple programs.
* Collaborate with package, PCB, and connector teams to evaluate layout tradeoffs, stackups, materials, and routing strategies impacting endtoend channel performance.
* Correlate simulation results with lab measurements, supporting board bringup, debug, and postsilicon characterization using oscilloscopes, TDRs, VNAs, and other lab tools.
* Identify and drive resolution for crossdomain issues involving signal integrity, power integrity, timing, EMI/EMC, and thermal interactions.
* Provide technical leadership through design reviews, mentoring engineers and influencing architectural decisions with datadriven recommendations.
* Support customer engagements, field issues, or escalations requiring deep SI/PI expertise.

What We're Looking For

* Bachelor's degree in Computer Science, Electrical Engineering or related fields and 10-15 years of related professional experience OR Master's degree in Computer Science, Electrical Engineering or related fields with 5-10 years of experience.
* Proven record of technical leadership and ownership across multiple product generations, driving SI/PI excellence from early architecture through production.
* Deep expertise in highspeed signal integrity analysis and design, including transmission line theory, channel modeling, and loss/jitter/noise mechanisms.
* Extensive handson experience with advanced highspeed interfaces, such as DDR4 / DDR5 / LPDDR, HBM, PCIe Gen4 / Gen5 / Gen6, Ethernet (25G/50G/100G+ NRZ and PAM4 SerDes), highspeed chiptochip links
* Strong understanding of package, PCB, and connector effects on endtoend channel performance.
* Expertise in prelayout and postlayout SI simulations, timing margin analysis, eyediagram analysis, jitter decomposition, and compliance validation.
* Deep knowledge of power distribution network (PDN) design, including ondie, package, and boardlevel power delivery.
* Expertise in AC and transient PI analysis, impedance target formulation, decoupling strategies, VR design, and noise mitigation.
* Practical experience analyzing and resolving simultaneous switching noise (SSN), ground bounce, and rail collapse issues.
* Expertlevel proficiency with industrystandard SI/PI tools, such as Cadence Sigrity (PowerSI, SystemSI, OptimizePI), Siemens HyperLynx, Keysight ADS / EMPro, Ansys HFSS / SIwave, Equivalent extraction and EM simulation tools.
* Experience collaborating with memory, SerDes, PHY, silicon, packaging, thermal, mechanical, and validation teams to resolve crossdomain issues.
* Handson experience supporting board bringup, lab debug, and postsilicon validation, correlating simulation results with lab measurements.
* Ability to act as a technical authority and decision maker for SI/PI architecture and design tradeoffs across programs.
* Strong communication skills, capable of clearly presenting technical risks, tradeoffs, and recommendations to engineering leadership and executive stakeholders.
