Principal Signal Integrity Engineer, Pathfinding

Role overview

Signal integrity work

• Generate and validate electrical models for packages, substrates, and interconnects using field solvers and circuit simulation.
• Evaluate forward-looking substrate and packaging technologies and their signal-integrity implications.
• Analyze feasibility and drive I/O and channel co-optimization.
• Develop package- and system-level design rules based on electromagnetic analysis.
• Define link budgets and methods correlating simulations with measured silicon results.
• Work across signal integrity, circuit and chip design, packaging R&D, and system integration.
• Write analysis reports, modeling methodology documents, and design-rule specifications.

Required qualifications

• MS or PhD in Electrical Engineering or related field; MS candidates need strong electromagnetic and SI fundamentals. PhD is preferred, not sufficient without practical capability.
• 10+ years of signal or power integrity analysis for high-speed interface technologies.
• Extensive electromagnetic and transmission-line theory applied to differential and single-ended interfaces.
• Extensive time- and frequency-domain simulation experience; ADS, HSPICE, SPECTRE, or equivalent.
• Deep electromagnetic field-solver experience, including setup, mesh strategy, and validation; Q3D, SIWAVE, HFSS, or equivalent.
• Working knowledge of oscilloscopes, TDR, and VNA.
• Able to own work, collaborate across disciplines, and make consequential analytical decisions.
• Strong written and verbal communication for technical reports and specifications.

Preferred qualifications

• Familiarity with memory I/O architectures and signal-integrity constraints.
• Advanced packaging experience, including 2.5D/3D integration, embedded die, or high-density organic substrates.
• Post-silicon characterization correlating simulation with measured TDR, insertion loss, eye diagrams, or BER.
• Some familiarity with optical-link modeling.
• Willingness to learn and apply AI-based methods to modeling and simulation workflows.
• Pathfinding or advanced development experience where analysis methods are developed.

Compensation

• Estimated US base salary is $119,000–$320,000 per year.
• Additional compensation may include benefits, bonuses, and equity; stated salary range reflects base pay.

Benefits

• Benefits include medical, dental, vision, income protection, paid family leave, paid time off, and paid holidays.
