Our mission is to democratize AI by significantly reducing the Total Cost of Ownership (TCO) of hardware systems - a critical barrier to large-scale adoption. Our proprietary MIMO-on-copper technology powers a chiplet-based AI memory fabric that is high-performance, scalable, and energy-efficient. Unlike traditional interconnects, our solution reduces energy consumption while preserving high bandwidth and ultra-low latency, unlocking unprecedented efficiency for large-scale AI training and inference. Kandou AI's architecture is not an incremental improvement - it represents a fundamental shift in how AI hardware is designed for the future. We are actively looking for a Characterization Engineer for our laboratory in Lausanne, Switzerland.   Job Presentation ### The characterization engineer will lead the end-to-end characterization of high-speed silicon devices and SerDes operating at symbol rates above 20 Gbaud. This role is central to validating Kandou's next-generation analog and mixed-signal designs, ensuring performance, robustness, and efficiency across PVT conditions. You will work directly in the laboratory, in close collaboration with IP architects, digital and analog design teams, and contribute directly to the production ramp-up of this revolutionary interconnection technology.   Responsibilities ### • Lead the end-to-end characterization of high-speed SerDes operating above 20 Gbaud. • Perform jitter, eye diagram, BER, and margin measurements across PVT conditions. • Characterize full electrical parameters of transmitters and receivers. • Perform S-parameter, TDR, and insertion loss measurements. • Use high-speed oscilloscopes, VNA, and spectrum analyzers for device evaluation. • Collaborate with IP architects, digital and analog design teams to refine and validate designs. • Document test results, methodologies, and procedures. • Write and design test scripts in Python for automation, data analysis, and report generation. • Contribute to the definition of test plans and the continuous improvement of laboratory methodologies.   Required Experience ### • Proven experience in silicon device characterization over PVT. • Hands-on experience with high-speed oscilloscopes, VNA, and spectrum analyzers. • Experience in defining test plans and procedures. • Proficiency in Python or other object-oriented languages for test automation and data analysis. • Experience with PAM or multi-tone modulation schemes (a plus). • Experience in SerDes characterization (a plus). • Minimum 5 years of relevant industry experience.   Required Skills ### • Autonomous with a strong sense of responsibility and commitment. • Effective communicator and collaborative team player. • Great interest in high-speed analog circuit characterization. • Good understanding - or ability to learn quickly - of SI concepts, modulation schemes, and TX/RX fundamentals. • Ability to manage multiple tasks in a dynamic and energetic environment. • Experience with high-speed laboratory equipment (oscilloscopes, VNA, spectrum analyzers). • Experience with schematic entry or PCB design (a plus).   Required Education ### • Bachelor's or Master's in electrical engineering, computer engineering, or equivalent professional experience.
