• Develop and validate electrical models for Transmission lines, vias, connectors, and PDN (Power Distribution Network) structure.

• Define stackups, impedance targets, and routing constraints.

• Evaluate and optimize Reflections, insertion/return loss, and Crosstalk and jitter performance.

Simulation & Modeling

• Use EM and circuit tools (e.g., HFSS, ADS, SIwave, PowerSI) for Frequencydomain and timedomain analysis.

• Build system/channel models (e.g., IBISAMI, eye diagrams).

• Run whatif studies to optimize performance and reduce design risk.

Testing & Validation

• Define and execute SI validation plans using VNA, TDR, TDT and highspeed measurement setups.

• Define test fixtures and correlation structures.

• Drive simulation-to-measurement correlation and root cause analysis.

• Drive design improvements based on measured data.

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).

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), and Emerging packaging and interconnect technologies.

• Contribute to next-generation architecture and roadmap development.

Preferred Qualifications:

• BS/MS in Electrical Engineering (or related field).

• 4+ years of relevant experience in SI/PI analysis and design.
