The Signal and Power Integrity (SI/PI) Engineer is responsible for ensuring the electrical integrity of high-speed digital and analog signals across complex PCB designs, and for maintaining clean, stable power delivery to all circuitry within defined performance specifications. This role requires deep expertise in SI/PI analysis methodologies and simulation tools, and directly impacts the reliability and performance of advanced communication systems developed for National Security applications.

• Perform SI/PI analysis for PCB designs
• Leverage prior experience in digital circuitry design and signal integrity analysis methods to analyze digital CCAs using analysis tools such as Hyper Lynx, HFSS, and SIwave
• Generate guidelines for layout and stack-up to ensure compliance with timing and signal quality specs
• Develop and validate IBIS models for accurate pre- and post-layout simulation
• Conduct power integrity analysis; minimize power rail noise, voltage droop, and power plane resonance
• Ensure power delivery network (PDN) stability across relevant frequency ranges, including target impedance analysis
• Optimize PCB interconnects to support the high speed demands of PCIe Gen 4/5, DDR4/5, LPDDR4/5
• Model and analyze SERDES interfaces
• Actively participate in peer and formal design reviews, evaluating root cause signal/power issues
• Validate and debug designs in the lab as required
• Work closely with layout engineers, applying knowledge of PCB stack-up and high-speed layout constraints
• Generate technical documentation and reports with SI/PI findings and recommendations

• Active SECRET Clearance
• Bachelor's Degree in Electrical Engineering or related field with 6+ years of relevant experience, or a Master's Degree with 4+ years, specializing in digital Circuit Card Assembly (CCA) design and SI/PI analysis using commercial tools (e.g., Hyper Lynx, Ansys SIwave).
• Understand transmission line theory, impedance matching, crosstalk, reflection, jitter
• Ability to model and analyze high-speed interconnects
• Familiarity with PCB fabrication and materials and how they impact high-speed digital design
• Strong…
