Electrical Engineer

Job Description

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
