Characterization Lead: SerDes & SI Expert (Travel 30%)

Kandou AI; Lausanne; Vor Ort; CHF 140.000 - 210.000; Vollzeit

Zusammenfassung

Kandou AI, based in Lausanne, Switzerland, seeks a Characterization Lead to own performance characterization of Zinal retimer silicon and the Randa AEC channel. This Principal/Senior Staff role is hands-on and provides technical leadership across silicon, signal integrity and validation teams, including partners in Taiwan.

You will define datasheet limits, guard-bands and class baselines, drive measurements up to 50 GHz, and ensure datasheet readiness for downstream qualification.

Qualifikationen

• 10 to 14 years of experience in SerDes/silicon characterization.
• Direct ownership of a characterization program whose results became datasheet limits or qualification thresholds for a shipping product.
• Strong VNA measurement experience to 50 GHz or beyond, including de-embedding, mixed-mode S-parameters (Sdd/Scc/Scd/Sdc) and insertion/return-loss mask interpretation.
• Hands-on TX/RX SerDes characterization, jitter decomposition, BER bathtubs, PVT shmoos and equalization/adaptation analysis.
• Demonstrated common-mode and mode-conversion measurement depth, with the ability to distinguish channel behavior from fixture and calibration artifacts.
• Statistical characterization and guard-band derivation across corners, with clear treatment of measurement uncertainty, sample size and aging.
• Experience with VNAs, oscilloscopes of at least 50 GHz bandwidth, BERTs, jitter instrumentation, thermal forcing and ATE characterization load boards.
• BS in Electrical Engineering or equivalent, with the technical communication and coordination skills to hand off defensible limits to validation and manufacturing teams.

Aufgaben

• Lead silicon and channel characterization from measurement planning and bench setup through analysis, limit derivation and documented hand-off to validation.
• Characterize TX/RX SerDes performance across process, voltage and temperature: swing, jitter, sensitivity, equalization, adaptation, CDR lock, BER bathtubs and shmoos.
• Own channel measurements to at least 50 GHz, including de-embedding, insertion/return loss, mixed-mode S-parameters and common-mode and mode-conversion behavior.
• Establish reference-paddle baselines and channel classes by gauge, reach and frequency; correlate HTDR-derived metrics with calibrated VNA measurements.
• Derive datasheet limits and guard-bands from measured distributions, accounting for uncertainty, sample coverage and aging; maintain traceable datasets and limit revisions.
• Assess carrier-loading and forwarded-clock tradeoffs using measured channel data and simulation, and translate the findings into supported configurations and characterization limits.
• Characterize power, energy per bit and thermal behavior across operating modes and corners; investigate equalizer noise amplification and channel/thermal interactions.
• Coordinate shared laboratory equipment and characterization milestones with validation teams; lead technical reviews and deliver limits in time for downstream qualification and screening.
