Job Summary
Aristas cutting-edge Ethernet platforms are built to push the limits of performance density and power efficiency. This wouldnt be possible without our Signal Integrity (SI) engineerswho design simulate and characterize interconnects enabling the fastest SerDes technologies in the industry. Were looking for a Senior Signal Integrity Hardware Engineer to join our Hardware Design team at headquarters in Santa Clara this role youll work at the intersection of advanced simulation next-generation SerDes (112G/224G PAM4) and innovative routing and packaging techniques. Your work will directly influence the architecture and layout of Aristas next- generation Ethernet systems for hyperscale AI and cloud networking.
- Perform 3D EM design and simulation of high-speed interconnects (channels vias packages and connectors) for 112G/224G PAM4 SerDes using tools such as Ansys HFSS SiWave and Cadence Sigrity.
- Develop and validate test vehicles to characterize next-generation PCB materials packages and interconnects.
- Conduct S-parameter and time-domain measurements (VNA TDR BERT) to extract channel performance and validate modeling correlation.
- Perform link-level analysis for advanced standards (Ethernet 800G/1.6T PCIe Gen6/Gen7 CXL) using tools such as Keysight ADS or Cadence SystemSI.
- Collaborate closely with hardware mechanical and packaging teams to optimize stack- up breakout and routing strategies for high-density designs.
- Research and prototype novel materials backplane concepts and low-loss interconnect topologies to meet next-generation performance targets.
- Support bring-up and debug of production boards working cross-functionally to root- cause SI/PI issues.
Qualifications :
- BS/MS/PhD in Electrical Engineering Physics or related field with a focus on electromagnetics signal integrity or high-speed digital design.
- Solid understanding of signal integrity theory S-parameter analysis and channel modeling.
- Hands-on experience with 2.5D/3D EM solvers (Ansys HFSS SiWave Sigrity CST).
- Strong lab skills using oscilloscopes VNAs TDRs BERTs and Ethernet compliance tools.
- Familiarity with advanced PCB materials (e.g. Megtron 7 Tachyon 100G SLP) and manufacturing constraints for high-speed design.
- Experience analyzing and simulating 56G/112G/224G PAM4 and NRZ serial links.
- Knowledge of power integrity and co-simulation techniques is a plus.
- Excellent communication and collaboration skills.
