Characterization Lead in Lausanne

we are redefining the economics of AI infrastructure.

Our mission is to democratise AI by significantly reducing the Total Cost of Ownership (TCO) of hardware systems — a critical barrier to scalable adoption

Our proprietary MIMO-over-copper technology powers a high-performance, chiplet-based AI memory fabric that is both scalable and energy-efficient.

Unlike traditional interconnects, our solution reduces power consumption significantly while preserving high bandwidth and ultra-low latency — unlocking unprecedented efficiency for AI training and inference at scale.

our architecture is not just an incremental improvement — it’s a foundational shift in how AI hardware is built for the future.

Responsibilities

• Lead silicon and channel characterization from measurement planning and bench setup through analysis, limit derivation and documented hand-off to validation.
• Characterize TX/RX Ser Des 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.
• 10 to 14 years of experience in Ser Des/silicon characterization and/or high-speed channel and signal integrity characterization following degree completion.
• 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 Ser Des 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.
• Useful Experience
• Characterization leadership for shipping 100G/lane or 200G/lane retimers, PHYs, AECs or AOCs.
• Deep mixed-mode characterization where common-mode behavior affects information transport and link margin.
• Experience producing datasheet limits that a separate validation team independently qualified.
• Multi-carrier or proprietary coding schemes, including OFDM-style subcarriers and space-time coding, and their characterization implications.
• Published work or patents in channel modeling, de-embedding or Ser Des characterization.
• MS or Ph D with a concentration in communications, RF/microwave engineering or signal integrity.

If this is the role you have been looking for and you want to be part of a growing Company, with an exciting future then we would love to hear from you.
