Electrical Engineer

Job Description 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
