About the role
Blue Origin is seeking a Signal Integrity (SI) Engineer to develop next-generation high-speed digital and RF systems, including advanced optical and RF interconnects. The successful candidate will lead SI analysis for high-speed serial links and RF interconnects up to ~70 GHz, using tools like HFSS, ADS, and IBIS-AMI.
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, adapt, and correlate IBIS-AMI models with measurements and full-wave simulations.
- Define PCB stackups, materials, impedance targets, and routing rules for SI-robust designs.
- Design SOLT/TRL structures, coupons, and procedures for VNA/TDR workflows.
- Measure and correlate S-parameters, loss, isolation, and channel performance across simulation and hardware.
- Diagnose and resolve SI issues including reflections, resonances, crosstalk, and mode conversion.
- Produce clear reports, guidelines, and review material for cross-functional teams.
Qualifications
- Bachelor’s degree in Electrical/Electronics Engineering or related field.
- 5+ years in SI, high-speed digital, or RF/microwave design.
- Proficiency with HFSS, ADS, and IBIS-AMI workflows.
- Experience defining PCB stackups 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.
Preferred Qualifications
- Master’s degree in EE or related field.
- Experience designing or characterizing channels/interconnects up to ~70 GHz.
- Background in antenna-adjacent PCB design (arrays, feed networks, front-end modules).
- Experience with package-to-PCB co-design.
- Familiarity with scripting (Python, MATLAB) for SI automation.
- Experience correlating BER/margin results to SI simulations.
- Exposure to space/aerospace hardware and reliability constraints.
Additional Requirements
- Must be a U.S. person (U.S. citizen or permanent resident) as required by applicable export control laws.
- Willingness to support occasional off-hours testing or lab work as project schedules require.
