Silicon & Transceiver Validation Engineer
On-sitePalo Alto, California, United States
Job Summary
Review transceiver architecture and specifications to develop comprehensive validation plans covering silicon, module, and system-level testing. Characterize Ethernet SerDes performance, validate internal data pipeline throughput, and perform chip-level characterization across voltage, temperature, and process corners. Execute laser/modulator performance tests, MCU controller firmware interactions, and system-level functional validation including host interoperability and IEEE 802.3 compliance. Build test setups, run reliability sequences like HTOL and LTOL, and develop Python automation scripts for data analysis. Drive root cause analysis with the SoC team while documenting procedures and results.
Required Qualifications
- 5+ years of experience in hardware validation, silicon characterization, or transceiver testing
- Hands-on high-speed serial link validation: eye diagrams, BER testing, jitter analysis, S-parameter measurements
- Proficiency with lab instrumentation: real-time oscilloscopes, BERT, optical power meters, OSA, VNA
- Experience developing and executing structured validation plans from design specifications
- Understanding of transceiver architectures and subsystems (SerDes, TIA, driver, laser, modulator)
- Familiarity with I2C, SPI, and serial communication protocols
- Python scripting for test automation
- BS/MS in Electrical Engineering, Physics, or equivalent
Desired Qualifications
- Experience with NRZ optical transceiver validation and silicon characterization across PVT corners
- Familiarity with CMIS or similar management interface specifications
- Experience with Ethernet standards and compliance testing
- equalization techniques and SerDes tuning (FFE, DFE, CTLE)
- Optical component characterization experience (laser IV/LI curves, modulator transfer functions)
- Experience in a startup or fast-paced development environment
