Job Description:
Overview
In the role of a SI Engineer within the Signal Integrity group you will be responsible for completing tasks on time and solving short and long term problems. You will be part of a technical group, responsible for improving SI/PI performance, completing production design analysis, and measurement and characterizing. This role will be working with customers and engineers across multiple sites, California US, Europe and Asia Regions.
Primary Responsibilities
1. Design & Analysis
Perform signal and power integrity analysis for high‑speed interconnects (PCB, package, MLO, probe card)
Develop and validate electrical models for:Transmission lines, vias, connectors
PDN (Power Distribution Network) structures
Define stack‑ups, impedance targets, and routing constraints.
Evaluate and optimize:Reflections, insertion/return loss
Crosstalk and jitter performance
2. Simulation & Modeling
Use EM and circuit tools (e.g., HFSS, ADS, SIwave, PowerSI) for:Frequency‑domain and time‑domain analysis
Build system/channel models (e.g., IBIS‑AMI, eye diagrams).
Run what‑if studies to optimize performance and reduce design risk.
3. Testing & Validation
4. Design Support & Collaboration
Provide design guidelines, constraints, and best practices to layout teams and electrical design engineers
Collaborate globally with engineering teams and customers
Support new product development programs (e.g., probe cards, load boards) 5. Continuous Improvement & Innovation
Improve modeling methodologies and design workflows
Reduce simulation cycle time and improve design quality
Stay current with:High-speed interfaces (PCIe, HBM, SerDes)
Emerging packaging and interconnect technologies
Contribute to next-generation architecture and roadmap development
