Electrical Engineer in Santa Clara, California at AEI-CIG

Job Summary

We are seeking a skilled Electrical Engineer to design and develop high-speed optical transceiver hardware for next-generation data communication systems. The ideal candidate will have strong experience in high-speed digital and mixed-signal design, signal integrity, and optical module development (e.g., SFP, QSFP, OSFP). This role involves full product lifecycle ownership from architecture through validation and production.

Key Responsibilities

• Design and develop high-speed optical transceiver modules (e.g., SFP+, QSFP28, QSFP-DD, OSFP)
• Perform schematic capture and oversee multilayer PCB layout for high-speed designs
• Conduct signal integrity (SI) and power integrity (PI) analysis for high-speed channels (NRZ/PAM4)
• Simulate high-speed links using industry tools and validate performance in lab environments
• Debug and troubleshoot hardware issues during bring-up and validation phases
• Perform compliance testing according to industry standards (e.g., IEEE 802.3, MSA specifications)
• Collaborate with cross-functional teams including firmware, mechanical, optical, and manufacturing engineers
• Support product qualification, manufacturing, and yield improvement efforts
• Generate detailed design documentation, test plans, and reports

Required Qualifications

• Bachelor’s or Master’s degree in Electrical Engineering or related field
• Strong understanding of high-speed interfaces (10G/25G/50G/100G/400G+)
• Experience with signal integrity concepts: impedance control, jitter, crosstalk, insertion/return loss
• Hands-on experience with lab equipment (oscilloscope, BERT, VNA, TDR)
• Experience with PCB design and schematic tools (e.g., Altium, Cadence Allegro)
• Familiarity with communication protocols such as Ethernet, I2C, SPI, MDIO

Preferred Qualifications

• Experience with PAM4 signaling and advanced modulation schemes
• Familiarity with optical components (lasers, photodiodes, TIAs, DSPs)
• Experience with simulation tools (e.g., Keysight ADS, Ansys HFSS)
• Knowledge of thermal design and high-density module packaging
• Scripting or programming skills (Python, MATLAB) for automation and analysis
• Experience with compliance and interoperability testing

Key Skills

• High-speed digital and mixed-signal design
• Signal and power integrity analysis
• Hardware debugging and problem-solving
• Cross-functional collaboration
• Attention to detail and documentation
