Essential Functions:

• 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 HyperLynx, HFSS, Si Designer and SiWave.
• Generate guidelines for layout and stack-up to ensure compliance with timing and signal quality specs.
• Minimize power rail noise, voltage droop, and power plane resonance.
• Ensure power staPebility across frequency ranges.
• Optimize PWB interconnects to support the high speed demands of DDR4, LPDDR4, and DDR5 memory technologies.
• Modeling SERDES speeds of up to 25 Gbps.
• Conduct power integrity analysis, including decoupling capacitor optimization.
• 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.

Qualifications:

• Bachelor’s Degree in Electrical Engineering or equivalent degree, and minimum 6 years of prior relevant experience specializing in digital circuit card assembly (CCA) board design, performing signal and power integrity analysis using commercial analysis tools (e.g. Hyperlynx, Ansoft SIwave).
• Active SECRET Clearance.
• Understand transmission line theory, impedance matching, crosstalk, reflection, jitter.
• Ability to model and analyze high-speed interconnects.
• Familiarity with PWB fabrication and materials and how they impact high-speed digital design.
• Strong logic/board debug, and analytical skills.
• Ability to collaborate with cross-functional teams (Components Engineering, ECAD, board design engineers, RF engineers, mechanical engineering, systems engineering, software engineering, and factory personnel).

Preferred Additional Skills:

• Experience in Aerospace / Defense.
• Experience using the following tools: Mentor Xpedition, HyperLynx and Ansoft SIwave, SI Designer, HFSS.
• S-parameter modeling.
• Experience with industry standards (JEDEC, IEEE).
• Involvement in board bring-up, EMI/EMC mitigation, and compliance testing.
• Excellent written, verbal, and presentation skills.
• Clear technical communication (written & verbal).
• Strong analytical and problem-solving skills.
• Experience with project leadership and EVM.

In compliance with pay transparency requirements, the salary range for this role is $111,515 - $161,599.
