Job description

SI/PI Engineer in HBM Design Architecture

Micron Technology is seeking an experienced SI/PI Engineer to execute high‑quality SI/PI analysis for interposers, packages, and silicon channels, contributing directly to HBM design sign‑off and product success. The role involves complex, multi‑disciplinary SI/PI initiatives across multiple HBM product generations—including early interposer channel analysis, equalization co‑design, PDN architecture, and system PI analysis—to ensure Micron’s HBM SI/PI architecture remains the industry benchmark for signal quality, power delivery integrity, and interface reliability.

Responsibilities

• Signal integrity channel analysis for 2.5D and 3D silicon interposer, including frequency‑domain characterization (insertion loss, return loss, PSXT, IL‑to‑XT ratio) and time‑domain analysis (eye diagram, BER, jitter decomposition).
• Conduct mask‑based timing analysis using time‑domain simulations (e.g., SPICE, ADS).
• Support power integrity and PDN analysis, including impedance modeling and transient response analysis.
• Electromagnetic extraction and modeling of signal and power delivery channels (PCB, package, interposers, etc.).
• Automate sign‑off processes and work with EDA suppliers to improve tool accuracy and analysis flow.

Minimum Qualifications

• 5 years of experience in signal integrity (SI) and power integrity (PI) modeling and analysis.
• Deep understanding of SI/PI, electromagnetic and transmission line theory, I/O design.
• Experience in circuit simulation such as Keysight ADS and Synopsys HSPICE.

Preferred Qualifications

• 7+ years of experience in signal integrity and power delivery network (PDN) modeling and analysis.
• Experience in SI/PI modeling and analysis for 2.5D/3D advanced packaging (CoWoS, EMIB, interposer‑based designs), including time‑domain analysis (eye diagram, BER, jitter decomposition, PDN) and frequency‑domain characterization (S‑parameters, PDN impedance).
• Experience with mask‑based timing budget and jitter analysis with time‑domain simulation (SPICE, ADS, etc.).
• Experience with high‑speed interfaces such as DDR, HBM, UCIe, PCIe, and SERDES.
• Proficiency in simulation and analysis using industry‑standard EDA tools, including ANSYS HFSS/SIwave, Keysight ADS, Synopsys HSPICE, Cadence PowerSI/PowerDC.

The US base salary range that Micron Technology estimates it could pay for this full‑time position is: $146,000.00 - $297,000.00 a year.

Additional Compensation May Include Benefits, Bonuses and Equity.

As a world leader in the semiconductor industry, Micron offers a comprehensive benefits program to support health, financial security, and work‑life balance, including medical, dental and vision plans, paid family leave, paid time‑off, and paid holidays.
