Signal and Power Integrity Engineer, Senior (IoT)

Job Title

Signal and Power Integrity Engineer, Senior (IoT)

Role Summary

Senior engineer responsible for signal integrity (SI) and power integrity (PI) analysis for package and system-level designs for mobile/IoT products. The role works with IC, package substrate, PCB designers and PHY owners to ensure system-level constraints are met before package tape-out.

Will perform extraction and simulation, provide design guidelines, develop automated analysis flows, and communicate findings to cross-functional teams (PHY, PCB, packaging groups).

Experience Level

Senior — the role expects experienced engineers. Relevant postings specify multi-year experience in DDR/SerDes and package/PCB/system design (typically 3+ years of applicable experience).

Responsibilities

Primary responsibilities include technical analysis, design guidance, and process development.

• Perform package extraction for time-domain and frequency-domain analyses.
• Conduct system-level SI/PI analysis for DDR, SerDes and mixed-signal interfaces.
• Assess impact of ball assignments and PCB/package interactions on system performance.
• Provide and update package design guidelines to meet PHY/IP specifications (PCIe, UFS, USB, MIPI, LPDDR, etc.).
• Develop and automate design and analysis flows to improve throughput and repeatability.
• Create technical documentation and presentations for design reviews and handoffs.

Requirements

Must-have technical skills and domain experience; preferred skills listed separately.

• 3+ years of experience with DDR/SerDes in package, PCB or system design for mobile/IoT applications.
• Strong knowledge of electromagnetics, transmission line theory and crosstalk.
• Proficiency with field solvers such as HFSS, Q3D, Sentinel-PSI and Clarity.
• Experience with circuit/signal simulation tools such as ADS and Hspice.
• Working knowledge of PCB/package layout tools (Cadence Allegro/APD/Sip or Mentor Xpedition).
• Experience performing package extraction and system-level analysis and translating results into actionable design guidelines.
• Ability to develop and automate analysis flows and produce clear technical documentation.

Nice-to-have:

• Experience applying AI/ML techniques to improve engineering efficiency.
• Programming or scripting (C/C++, Python, Perl) and Matlab experience.
• Familiarity with interface design specifications: LPDDRx, MIPI (CSI, DSI), PCIe, UFS.

Education Requirements

Qualifications mention Bachelor's, Master's or PhD in Chemical Engineering, Electrical Engineering, Mechanical Engineering, or a related technical field. The posting specifies degree-plus-experience options (e.g., Bachelor's + ~2 years, Master’s + ~1 year, or PhD). Equivalent practical experience is implied as an alternative in the role description.
