Signal Integrity / Power Integrity (SI/PI) Engineer

We are looking for an experienced SI/PI Engineer with strong expertise in high-speed semiconductor and system-level Signal Integrity and Power Integrity analysis.

Key Responsibilities

- Perform end-to-end SI/PI analysis across Die, Package, Board and System.
- - Analyze and optimize high-speed SerDes, DDR/LPDDR and other high-speed interfaces.
- - Perform channel analysis, S-parameter extraction, crosstalk, eye-diagram and PDN analysis.
- - Develop 2D/3D electromagnetic models and perform package/board interconnect analysis.
- - Support product development from specification and architecture through design, validation and product release.
- - Correlate simulation results with lab measurements and troubleshoot SI/PI issues.
- - Work closely with ASIC/SoC, package, PCB, hardware, validation and system teams.

Required Skills

- 5–15 years of relevant SI/PI experience.
- - Strong understanding of Signal Integrity and Power Integrity principles.




- - Hands-on experience with high-speed interfaces such as SerDes and DDR/LPDDR.
- - Robust knowledge of transmission lines, S-parameters, crosstalk, eye diagrams, jitter and PDN.
- - Experience in package and/or board SI/PI analysis.
- - Experience with S-parameter extraction, 2D/3D EM modeling and simulation-to-measurement correlation.

EDA / Simulation Tools Hands-on experience with multiple SI/PI tools such as:

Ansys HFSS / SIwave, Cadence PowerSI / SystemSI, Siemens HyperLynx / Advanced Solver, Keysight ADS, HSPICE / Broadband SPICE or equivalent tools.

Preferred Experience

- PCIe, XAUI, SGMII, JESD204, 10G-KR or similar high-speed protocols.
- - NAND, SSD, DIMM, memory or high-speed semiconductor products.
- - Programming/scripting using Python, Perl or Tcl.
- - Robust analytical, debugging and cross-functional communication skills.
