Our technology powers product innovation in the most data-demanding industries today, including data centers, networking, storage, artificial intelligence, 5G wireless infrastructure, and autonomous vehicles. Customers partner with us for mission-critical data communication, our innovative technologies, and our proven track record. Together, we enable the next generation of digital technology.

Signal Integrity and Power Integrity (SI / PI) Engineer

We are seeking a highly skilled Signal Integrity (SI) and Power Integrity (PI) Engineer to join our team, focussing on high-speed electrical wireline systems. The successful candidate will play a critical role in designing, analyzing, and optimizing high-performance interconnects, ensuring signal and power integrity in high-speed package, chip-on-board, PCB, and cable designs.

We welcome candidates at various experience levels for this role. Our offers will align with the level during the interview assessment.

What You'll Do

Conduct SI / PI simulations and analysis for high-speed interfaces (e.g. 106Gbps and higher PAM4 differential signaling)

Develop simulation models based on electromagnetic analysis for PCB traces, vias, connectors, cables, IC packages, and photonics interconnects to ensure optimal SI / PI performance

Perform frequency-domain and time-domain analysis, including S-parameters, impedance matching, crosstalk, return loss, insertion loss, and power supply AC noise analysis

Work closely with cross-functional IC design teams to optimize high-speed interface layout floorplans to optimize SI / PI performance across a wide range of different interconnect technologies (e.g. C4 bump map for flip-chip BGA packages, uC4 bump map for silicon interposer chiplet designs, C4 bump map for chip-on-board pluggable modules)

Define design guidelines and develop reference designs for high-speed interconnects and power distribution networks (PDN)

Work closely with internal teams and external partners for hardware design, PCB layout, and manufacturing to ensure optimal SI / PI performance

Validate SI / PI performance through lab measurements using oscilloscopes, vector network analyzers (VNAs), time-domain reflectometry (TDR), and other test equipment

Identify and mitigate signal degradation issues such as reflections, jitter, and noise coupling

Support package and PCB stack-up design, material selection, and layout optimization for high-speed signal routing

Drive improvements in design methodologies and best practices for high-speed electrical systems

What You'll Need

Masters / PhD in Electrical / Computer Engineering, Engineering Science, or a related field

Previous experience with electromagnetic modelling and simulation

Strong understanding of microwave / RF and SI / PI fundamentals, including transmission line theory, s-parameters, crosstalk, channel simulation, PDN and EMIR.

Proficiency with EDA Tools : KeySight ADS, Ansys Electronic Desktop (HFSS and SIwave), Cadence Sigrity PowerSI / DC, or other similar simulation / modeling tools.

Ability to interpret s-parameters, impedance profiles, and power distribution network characteristics

Experience with high-speed IC package and PCB design

Proficiency in using lab equipment such as oscilloscopes, TDR, VNA, and spectrum analyzers for signal integrity and power integrity validation

It'd Be Amazing If You Had

Familiarity with IEEE 802.3 (Ethernet) and OIF standards

Experience with high-speed (e.g. 106Gbps and higher) NRZ and PAM4 SerDes

Understanding of digital and analog equalization and familiar with using IBIS-AMI model in channel simulation

Scripting knowledge (Python, Matlab, etc.) for automation of SI / PI simulations

We have a flexible work environment to support and help employees thrive in personal and professional capacities.

You’ll also be eligible for competitive benefits described as per below :
