Power Integrity Engineer
Lumilens, Bengaluru, India
What you will do
- Perform PI simulations using tools like Ansys SIwave, Keysight ADS, or Cadence Sigrity to model and optimize PDN for OSFP modules, targeting <1mΩ target impedance across 10kHz-100MHz bandwidth.
- Analyze and mitigate power rail decoupling, VRMs, and bypass capacitor placement for multi-rail supplies (0.8V core, 1.8V I/O, 3.3V aux) in high-current OSFP designs up to 100W+.
- Collaborate on PCB stackups, via optimization, and plane splitting to reduce simultaneous switching noise (SSN) and ground bounce in 112G PAM4 SerDes environments.
- Validate designs through lab measurements using VNA, oscilloscopes, and power analyzers; correlate simulations with hardware prototypes.
