Job Description:

In the role of SrPrincipal Signal Integrity Engineer, 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.

Key Responsibilities:

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, and PDN (Power Distribution Network) structure.
Define stack-ups, 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 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.

Testing & Validation

Define and execute SI validation plans using VNA, TDR, TDT and high-speed 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).
8+ years of relevant experience in SI/PI analysis and design.
