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.

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.

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.

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
