Serdes Characterization & Post-Silicon Validation Engineer

Seattle💼 Full-time💰 $170,000–$170,000🗓 2026-09-17 → 2026-09-26

Core

Lead post-silicon bring-up, characterization, and validation of high-speed SerDes interfaces (NRZ/PAM4) in complex SoCs for satellite platforms.

Role type

Senior IC SerDes Characterization & Post-Silicon Validation Engineer

Builds

High-speed test and validation capability, automated characterization environments, and system-level link operation for satellite SoCs.

Domain

Aerospace / High-Speed Digital Interfaces / Signal Integrity

Deliverable

production ML models | product features | dashboards & analysis | research | client delivery | infrastructure | physical/clinical work -> physical/clinical work (Note: Corrected to 'physical/clinical work' is wrong, should be 'product features' or 'infrastructure'. Let's map to 'product features' as it's about bringing up the interface for the product, or 'infrastructure' for the lab. The prompt says 'physical/clinical work' is an option. This is neither. It is 'product features' (validating the interface) or 'infrastructure' (building the lab). Given the mix, 'product features' fits the validation of the SoC interface best, but 'infrastructure' fits the lab building. Let's use 'product features' as the primary output of the role is the validated interface functionality.) -> Actually, looking at the options: 'production ML models | product features | dashboards & analysis | research | client delivery | infrastructure | physical/clinical work'. The role builds the lab (infrastructure) and validates the interface (product feature). I will select 'product features' as the primary deliverable of the engineering work on the SoC.

Required skills
