Job summary

Lightmatter is seeking a Power Integrity engineer to drive the next generation products from concept to development. You will be part of the Signal Integrity, Power Integrity and Packaging team, tasked with influencing the package and system architecture, design, and analysis through lab bring-up to meet the product's power integrity requirements.

This position offers a unique opportunity to solve complex interactions across digital, analog and photonics domains while meeting stringent power

Qualifications

• MS or PhD in Electrical Engineering or a related field.
• 3+ years of experience in power delivery and power integrity analysis for high performance CPUs and compute SoCs.
• Proficiency in using simulation and analysis tools for power integrity, including PowerSI, PowerDC, IDEM, H-Spice and Keysight ADS.
• Experience in DC-DC converter design.
• Experience with PCB design and layout considerations for power integrity, including layer stack-up assignment, power plane partitioning, capacitor selection and placement, and microvia/PTH design.
• Strong problem-solving and debugging skills for power integrity-related issues.

Responsibilities

• Support the design and analysis of Power Delivery Networks (PDNs) for digital and analog SoC domains, including path from voltage regulators to on-chip decoupling capacitors.
• Assist in modeling regulator characteristics such as switching ripple and transient response to aid in component selection (controllers, passives, etc.).
• Use commercial simulation tools (e.g., 2.5D EM solvers) to extract PCB and package impedance profiles and help generate N-port models.
• Perform basic time-domain and frequency-domain simulations to evaluate supply rail behavior and identify potential issues such as voltage droop or overshoot.
• Conduct lab measurements to validate power integrity design, including use of programmable loads and oscilloscopes to capture transient response.
• Work closely with hardware designers, layout engineers, and system integrators to implement PDN design improvements and validate results.
• Participate in design reviews and contribute to documentation of analysis results, test procedures, and design recommendations.
• Help monitor and review PDN constraints during layout and provide feedback based on simulation or measurement data.
• Support senior engineers in system-level tradeoff studies and architectural evaluations related to power integrity.
