Sr. Signal Integrity Engineer - High-Speed Digital / RF

Application close date: Applications will be accepted on an ongoing basis until the requisition is closed. At Blue Origin, we envision millions of people living and working in space for the benefit of Earth. We’re working to develop reusable, safe, and low‑cost space vehicles and systems within a culture of safety, collaboration, and inclusion. Join our team of problem solvers as we add new chapters to the history of spaceflight! Blue Origin is pioneering the future of space‑based communications with TeraWave, a revolutionary satellite communications network designed to deliver symmetrical data speeds of up to 6 Tbps anywhere on Earth. This multi‑orbit constellation will consist of optically interconnected satellites in low Earth orbit (LEO) and medium Earth orbit (MEO), providing enterprise‑grade connectivity for critical operations worldwide. 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. You will own end‑to‑end channel design and validation—from simulation and modeling through PCB stack‑up definition, calibration structures, and lab characterization up to ~70 GHz. Key Responsibilities Signal integrity ownership – Lead SI analysis for high‑speed serial links and RF interconnects up to ~70 GHz. 3D EM simulation – Use HFSS to model interconnects, packages, transitions, and antenna‑adjacent structures. Circuit/channel simulation – Use ADS for linear/nonlinear circuit modeling, S‑parameter work, and trade studies. IBIS/AMI modeling – Build, adapt, and correlate IBIS/AMI models with measurements and full‑wave simulations. High‑speed PCB architecture – Define stack‑ups, materials, impedance targets, and routing rules for SI‑robust designs. Calibration and de‑embedding – Design SOLT/TRL structures, coupons, and procedures for VNA/TDR workflows. Hardware characterization – Measure and correlate S‑parameters, loss, isolation, and channel performance across simulation and hardware. Root‑cause analysis – Diagnose and resolve SI issues including reflections, resonances, crosstalk, and mode conversion. Documentation and communication – Produce clear reports, guidelines, and review material for cross‑functional teams. Basic 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 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. 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. Compensation Range CA applicants: $197,529.00 – $276,539.55. WA applicants: $197,529.00 – $276,539.55. Other site ranges may differ Other locations have their own compensation ranges. Culture Statement At Blue Origin, we are dedicated to building an authentic workplace.
