Signal Integrity Engineer

Job Title

Job Description

Signal Integrity Analysis

• Perform pre-layout and post-layout signal integrity simulations for high-speed interfaces including PCIe, CXL, Ethernet, Ser Des, and DDR5/DDR6 technologies under the guidance of senior SI/PI engineers.
• Analyze channel performance, insertion loss, return loss, crosstalk, and timing margins to support robust platform design.
• Evaluate design tradeoffs and provide recommendations to improve signal quality and overall system performance.

Modeling & Simulation

• Develop and execute channel models using industry-standard tools such as HFSS, ADS, HSPICE, Sigrity, or comparable simulation environments.
• Support stackup development, impedance control requirements, and routing rule definition for high-speed PCB designs.
• Assist with connector, cable, package, and channel characterization activities.

Lab Validation & Correlation

• Support signal integrity validation using high-speed oscilloscopes, Vector Network Analyzers (VNA), Time Domain Reflectometers (TDR), and Bit Error Rate Testers (BERT).
• Correlate simulation results with laboratory measurements and identify opportunities for model refinement.
• Assist with compliance testing and validation for industry-standard interfaces.

Design & Platform Support

• Collaborate with hardware design and PCB layout engineers to ensure adherence to SI best practices and design guidelines.
• Provide technical support for routing strategies, connector selection, cable design, and high-speed channel optimization.
• Participate in EVT, DVT, and PVT bring-up activities and support debug efforts for signal integrity-related issues.

Documentation & Reporting

• Maintain simulation reports, measurement results, compliance documentation, and engineering recommendations.
• Document methodologies, findings, and corrective actions to support design reviews and product releases.
• Contribute to the development of SI design guidelines and best practices.

• Bachelor's or Master's degree in Electrical Engineering or a related technical discipline.
• 2–5 years of experience in Signal Integrity, High-Speed Digital Design, Hardware Engineering, or related disciplines.
• Internship, co-op, academic research, or project experience involving channel simulation, high-speed interfaces, or laboratory measurements is highly desirable.
• Working knowledge of transmission line theory, electromagnetic fundamentals, PCB stackups, and high-speed channel design.
• Familiarity with SI simulation and modeling tools such as HFSS, ADS, HSPICE, Sigrity, CST, or equivalent.
• Experience working with laboratory equipment including oscilloscopes, VNAs, TDRs, and related measurement tools.
• Understanding of impedance control, crosstalk, jitter, eye diagram analysis, and channel loss mechanisms.
• Strong analytical, troubleshooting, and problem-solving skills.
• Excellent written and verbal communication skills with the ability to present technical findings clearly.
• Demonstrated attention to detail and ability to work effectively in cross-functional engineering environments.

• Experience supporting AI, GPU, server, storage, networking, or data center hardware platforms.
• Familiarity with PCIe Gen4/5/6, CXL, DDR5/DDR6, Ethernet, Ser Des, and related industry standards.
• Knowledge of Intel and/or AMD server architectures.
• Experience supporting EVT, DVT, and PVT development cycles.
• Understanding of package, board, connector, and cable interactions in high-speed systems.
• Exposure to compliance testing methodologies and industry certification requirements.
• Experience collaborating with SI, PI, hardware design, layout, mechanical, and manufacturing engineering teams.
• Familiarity with power integrity concepts and their interaction with signal integrity performance.

• Competitive salary commensurate with experience and qualifications.
• Comprehensive medical, dental, and vision insurance.
• 401(k) with company match.
• Flexible Spending Account (FSA).
• Health Savings Account (HSA).
• Paid holidays, vacation, and sick time.
• Tuition reimbursement programs.
• Professional development and training opportunities.
• Employee discount programs through Perks at Work.
• LEAP…
