About the role:
As a SI/PI Package Design Engineer focused on 224G Ethernet switches, your role is critical in enabling next-generation ultra-high-speed networking products. You’ll be responsible for ensuring signal and power integrity across high-speed interfaces in advanced package and PCB designs, pushing the limits of current technology.
Key responsibilities:
- Signal Integrity (SI):
- Model and simulate high-speed interfaces (e.g., 224G-PAM4 SerDes).
- Perform channel simulations (TX-to-RX) across packages and PCBs.
- Work with IBIS-AMI, S-parameter models, and tools like Ansys HFSS, Keysight ADS, or Cadence Sigrity.
- Optimize interconnects to meet eye diagram, BER, and insertion/return loss targets.
- Validate compliance with standards like IEEE 802.3df/802.3dj and UAL.
- Power Integrity (PI):
- Analyze and design PDN (power delivery network) for core and I/O voltages.
- Ensure low impedance across required frequency range using de-cap optimization and VRM modeling.
- Use tools like PowerSI, PowerDC
Package/Board Design Collaboration:
- Co-design with package layout engineers (e.g., substrate, flip-chip, organic packages).
- Define breakout strategies for dense BGA interfaces
- Guide stackup, via, and routing constraints in both package and board to enable 224G signaling.
Cross-Functional Collaboration:
- Interface with ASIC, system, layout, and test teams.
- Provide SI/PI guidelines and design constraints to enable electrical compliance.
- Support bring-up and debug using scopes, VNAs, TDRs, etc.
Skills & Tools:
- Simulation Tools:
- SI: ADS, HFSS, ADK, HSPICE
- PI: PowerSI, PowerDC
- Modeling:
- IBIS-AMI, S-parameters, RLGC models
- Analysis:
- Time-domain and frequency-domain signal analysis
- Crosstalk, jitter, eye closure, PDN impedance
- Fabrication Knowledge:
- HDI PCB and advanced package materials (e.g., Megtron 7, Ajinomoto)
- Low-loss stackup optimization, via-in-pad, via stub mitigation
Qualifications:
- BS/MS in Electrical Engineering or related field.
- 5+ years in Signal Integrity
Title:
- Sr. High-Speed Package Design Engineer
Compensation:
Individual compensation will be commensurate with the candidate’s experience and aligned with Auradine’s internal leveling guidelines and benchmarks.
