Signal and Power Integrity (SIPI) Engineer

We are seeking a talented Signal Integrity and Power Integrity Engineer to join our hardware engineering team. The ideal candidate will possess strong expertise in SI/PI simulation and analysis, combined with solid fundamentals in circuits, electromagnetics, and hardware design. This role is critical to ensuring the electrical performance and reliability of our next-generation protective relay products.

• Perform signal integrity and power integrity simulations and analysis for high-speed digital designs
• Conduct pre-layout and post-layout SI/PI assessments to ensure design compliance with specifications
• Develop and validate models for signal integrity analysis including IBIS, SPICE, and S-parameter models
• 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

• Bachelor's degree in Electrical Engineering, Computer Engineering, or related field (Master's 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
• Self-motivated with ability to manage multiple priorities
