Signal Integrity & Power Integrity Engineer
Mountain View, CA. Posted 4 months ago
The role
You will own signal-integrity and power-integrity analysis and signoff for the AI platform across silicon, package, board, and system. You will model high-speed interface channels and power-delivery networks and develop AI assisted tool flows.
What you will do
- Own signal-integrity and power-integrity analysis and signoff for DensityAI’s AI platform across silicon, package, board, and system
- Model high-speed interface channels and power-delivery networks
- Set the SI/PI budgets the design is built to
- Partner with package, PCB, physical-design, and architecture teams
- Use and develop AI assisted tool flows to accelerate SI/PI modeling, extraction, and signoff timelines
Required qualifications
- 5+ years of SI/PI experience on very high-performance designs at advanced technology nodes (7nm or better) and high-speed interfaces (PCIe, DDR/LPDDR, HBM, 112G+ SerDes, or equivalent)
- Exceptional abilities across SI/PI analysis: link budgeting, channel modeling and S-parameter extraction, IBIS-AMI, IR-drop and power-delivery-network (PDN) analysis, and EM/thermal-aware signoff
- Hands-on with industry-standard tools (Ansys HFSS / SIwave / RedHawk, Cadence Sigrity / Clarity, Synopsys, Keysight ADS or equivalent) for extraction, EM, and PDN analysis
- Demonstrated ability to work closely with package, PCB, physical design, and architecture teams to set and sign off SI/PI budgets across die–package–board
Nice to have
- 2.5D / 3D and multi-die packaging (CoWoS, EMIB, chiplets, HBM interfaces)
- jitter / equalization design
- co-packaged optics
- post-silicon SI/PI correlation and lab validation
Benefits
- equity grant per company guidelines
- medical / dental / vision
- 401(k)
- standard PTO
