Job summary

Blue Origin is seeking a Signal Integrity (SI) Engineer to develop next-generation high-speed digital and RF systems in Seattle. You will own end-to-end channel design and validation, leading SI analysis for high-speed serial links and RF interconnects up to ~70 GHz.

The ideal candidate has a Bachelor’s degree in Electrical/Electronics Engineering, 5+ years of experience in SI or RF design, and proficiency with tools like HFSS and ADS.

Benefits include comprehensive medical coverage, stock options, and paid time off.

Qualifications

• 5+ years in SI, high-speed digital, or RF/microwave design.
• Proficiency with HFSS, ADS, and IBIS/AMI workflows.
• Experience defining PCB stack-ups for high-speed/microwave designs.
• Hands-on VNA/TDR measurement experience.
• Strong understanding of transmission lines, S-parameters, loss mechanisms, jitter, crosstalk, and channel budgeting.
• Ability to work across RF, digital, packaging, and systems teams.

Responsibilities

• Lead SI analysis for high-speed serial links and RF interconnects up to ~70 GHz.
• Use HFSS to model interconnects, packages, transitions, and antenna-adjacent structures.
• Use ADS for linear/nonlinear circuit modeling, S-parameter work, and trade studies.
• Build and correlate IBIS/AMI models with measurements and full-wave simulations.
• Define stack-ups, materials, impedance targets, and routing rules for SI-robust designs.
• Design structures and procedures for VNA/TDR workflows.
• Measure and correlate S-parameters, loss, isolation, and channel performance.
• Diagnose and resolve SI issues including reflections, resonances, crosstalk, and mode conversion.
• Produce clear reports, guidelines, and review material for cross-functional teams.
