Hardware Signal Integrity (SI) Engineer

Akkodis is seeking a Hardware Signal Integrity (SI) Engineer for a Contract job with a client in Cupertino, CA or Austin, TX (Hybrid). Ideally looking for applicants with a solid background in high-speed SerDes design, Signal Integrity (SI) analysis, PCB and flex layout review, PCIe/USB4/Thunderbolt interfaces, channel simulation using HFSS/ADS, IBIS-AMI modeling, and SI validation using VNA/TDR measurement tools..

Rate Range: $85/hour to $88/hour; The rate may be negotiable based on experience, education, geographic location, and other factors.

Details

• The candidate will work within the Mac organization to support the system-level Signal Integrity (SI) design, analysis, and validation aspects of Mac products development. You should have deep knowledge and familiarity with all aspects of Signal Integrity for high speed SerDes, Parallel bus, and single ended signaling.

Key Qualifications:

• The candidate must have system-level Serdes design and analysis skills. The Serdes knowledge required includes understanding of transmitter and receiver equalization methods (including FFE, CTLE, DFE, VGA gain), CDR behaviors and modeling, link training algorithms and internal eye margining tool for NRZ, PAM3, and PAM4 signaling. Experiences on Multi-level signaling such as PAM3 and PAM4 are preferred.
• Serial bus expertise shall include the knowledges and experiences in various industry Serdes standards such as USB4, DiplayPort, HDMI, MIPI, SD, USB2, Ethernet, PCIe, USB3.1, and Thunderbolt. SI skills required include a good understanding in NRZ, PAM3, and PAM4 signaling and its statistical DOE analysis across channel variants, applying equalization and training as required for end-to-end channel analysis.
• Parallel bus interface expertise should include understanding of signaling specs and signal integrity signoff for DDR, GDDR, LPDDR, NAND interfaces, and common synchronous interfaces.
• Experiences and knowledges on the transmitter and receiver compliance tests and passive channel/component characterization for high speed Serdes are required.

Description:

• Hands-on experience with PCB and Flex layout review, including trace routing, impedance control, and return path analysis
• Understanding of high-speed digital interface protocols (PCIe, USB, DisplayPort, HDMI) and their electrical specification requirement
• Proficiency in channel modeling and end-to-end link simulation using industry-standard tools (Ansys HFSS, Keysight ADS, SIwave, PowerSI)
• Interconnect modeling capability, using S-parameter, W-elements, etc is required. An understanding of channel types including cabling, pcb materials, flex materials, and connector design methods and limitations is required.
• Relevant working knowledge of IBIS-AMI, HSPICE, Spectre, AMS, and Simplis models for system-level transient analysis is also necessary.
• Working knowledge of ADS is desired.
• Measurement expertise with frequency and time domain tools (VNA, TDR) including calibration & deembedding experiences is desired.
• Experience with Matlab/Python/PERL and other scripting languages is desired.
• Excellent documentation and communication skills, ability to work independently, and demonstrated ability to innovate are required.

Education:

• PhD (Preferred) with 3 years of industry experience, or Masters (minimum) with at least 5 years of industry experience.
