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

• Drive simulation-to-measurement correlation and root cause analysis
• Define SI validation plans using VNA, TDR, TDT and high‑speed measurement setups
• Define test fixtures and correlation structures
• Drive design improvements based on measured data

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

Required Qualifications

• BS/MS in Electrical Engineering (or related field)
• 4+ years of relevant experience in SI/PI analysis and design
• Strong understanding of:
  • Transmission line theory
  • Power integrity principles
  • Crosstalk and signal degradation mechanisms
• Experience with tools such as:
  • HFSS, ADS, SIwave, PowerSI, PowerDC, SPICE, Allegro, MATLAB

Preferred Qualifications

• Hands-on experience with measurement tools (VNA, TDR/TDT)
• Experience with high-speed interfaces (PAM4, SerDes, PCIe, HBM)
• Scripting/automation (Python, MATLAB)
• Experience in advanced packaging, probe cards, or fine-pitch interconnects

Core Skills

• Analytical problem solving and debugging
• High-frequency design expertise
• Data interpretation and modeling
• Cross-functional communication
• Ability to balance modeling accuracy vs. schedule execution
• Ability to apply engineering judgement to define model accuracy requirements

Typical Impact

• Improves first-pass success rate of designs
• Reduces cycle time through simulation-driven design
• Ensures compliance with high-speed performance requirements
• Minimizes field/customer issues tied to SI/PI performance

Skills:

Allegro PCB Designer, ANSYS HFSS, Cadence Tools, High Speed Interfaces, MATLAB, Power Distribution Design, Power Integrity, Probe Cards, PSpice Circuit Simulation, Python (Programming Language), SERDES, Signal Integrity, Signal Integrity Analysis, Transmission Line Design

Education & Experience:

Minimum of 5 years of related experience with a Bachelor’s degree; or 3 years and a Master’s degree; or a PhD without experience; or equivalent work | Required
