• Collaborate with PCB layout designers to optimize stackup routing and power delivery network design
• Analyze and troubleshoot signal integrity issues such as crosstalk reflection impedance discontinuities and EMI
• Evaluate power distribution network (PDN) performance including impedance analysis decoupling strategies and voltage droop
• Support hardware validation through correlation of simulation results with measurement data
• Create design guidelines and best practices for SI/PI optimization
• Interface with cross-functional teams including hardware design layout and product engineers

• Bachelors degree in Electrical Engineering Computer Engineering or related field (Masters preferred)
• 3 years of experience in signal integrity and power integrity analysis and simulation
• Experience with electromagnetic theory transmission line theory and high-speed digital design
• Proficiency with SI/PI simulation tools (e.g. Ansys HFSS SIwave Cadence Sigrity Keysight ADS or similar)
• Experience with SPICE simulation tools (e.g. Ansys Nexxim Synopsys HSPICE Cadence Spectre LTSPICE or similar)
• Solid understanding of circuit design fundamentals including analog and digital circuits
• Strong foundation in hardware design principles and PCB design considerations

• General modeling and simulation experience for hardware validation and verification
• Hands-on experience with hardware development lifecycle
• Experience with IBIS model development and validation
• Familiarity with S-parameter measurements and VNA operation
• Knowledge of DDR PCIe USB Ethernet or other high-speed interface standards
• Proficiency with scripting languages (i.e. Python) for automation and data analysis
• Experience correlating simulation results with lab measurements
• Understanding of EMC/EMI design principles
• Exposure to thermal simulation and analysis

• Strong analytical and problem-solving skills
• Excellent communication skills with ability to present complex technical concepts clearly
• Detail-oriented with strong organizational skills
• Ability to work collaboratively in a cross-functional team environment
