Silicon Validation, Test & Characterization Engineer (title will reflect experience)

Job description

Eliyan is building NuLink, a proprietary die-to-die chiplet interconnect fabric purpose-built for AI infrastructure at hyperscale. We are seeking a highly skilled engineer to execute high speed silicon validation efforts, ensuring our silicon platforms deliver industry-leading performance, quality, and reliability. You will work with a cross-functional team of industry experts that operate from first principles, innovate, and push the envelope to create high-volume and high-performance manufacturable products. We offer a fun work environment with excellent benefits. **Position Overview:** As a Silicon Validation Engineer, you will be a technical owner to drive early silicon bring-up, post-silicon validation strategy, and hands-on execution for high-speed interconnects such as multi-Gbps SerDes and PHYs. You will work closely with design, architecture, and systems teams to ensure seamless bring-up, thorough validation coverage, and successful productization of complex silicon solutions. ### Key Responsibilities: - Execute early silicon bring-up activities, including system initialization, validation infrastructure development, and test content creation for high-speed interfaces. - Define and drive comprehensive post-silicon validation plans for multi-Gbps SerDes, PHYs, and associated interconnect technologies (e.g., PCIe, CXL, Ethernet, DDR). - Develop robust automation frameworks and test scripts (e.g., Python, TCL) to improve validation efficiency and coverage. - Perform advanced electrical and protocol-level validation, including BER testing, jitter and eye diagram analysis, compliance testing, and margin assessments. - Correlate lab measurements with pre-silicon simulations and design expectations; drive debug and closure on discrepancies, identify and root-cause silicon, package, and board-level issues. - Work cross-functionally with design, architecture, system, and product engineering teams to optimize validation coverage and drive design-for-validation improvements. - Document validation results, issues, and recommendations in detailed technical reports and communicate findings clearly to engineering and executive leadership. - Support manufacturing and test engineering teams with validation methodologies to enable production ramp and customer readiness. ### Qualifications: - 3+ years of experience - Expertise in chip bring-up, post-silicon validation, and debug of high-speed interconnects - (e.g., PCIe, CXL, Ethernet, DDR, SerDes). - Hands-on experience with high-speed lab equipment (high-bandwidth oscilloscopes, BERT, DCA, VNAs, TDRs) and associated validation methodologies. - Fundamentals in signal integrity (SI), power integrity (PI), clock architectures, analog and mixed-signal, high speed DAC and ADC, equalization (CTLE, DFE), and link training protocols. - Ability to correlate silicon measurements to design simulations and models and drive systematic debug. - Strong scripting and automation skills (Python preferred). - Experience in PCB/evaluation board validation is a plus. - Excellent analytical, communication, and leadership skills. - MS or PhD in electrical engineering, computer engineering, physics or related fields
