Job summary

Delart is seeking an experienced engineer to lead high-speed signal integrity simulations for cutting-edge networking hardware. You will run electromagnetic analyses, verify PDN performance, and validate interfaces like PAM4 and NRZ across 25G/100G/400G/800G specs.

You will collaborate with PCB layout teams to optimize stack-ups and impedance control, and you will document methods and findings to guide hardware development in server and data-center systems.

Qualifications

• 5+ years of hands-on experience in signal integrity simulation for high-speed digital systems.
• Proficiency with HFSS, Sigrity, PowerSI, SIwave and ADS.
• Experience with PAM4 and NRZ high-speed interfaces.
• Strong PCB stack-up, impedance control, and fabrication knowledge.
• Excellent documentation and communication skills.

Responsibilities

• Perform high-frequency electromagnetic simulations for high-speed interfaces using HFSS and Keysight ADS.
• Execute comprehensive PDN analysis with industry tools.
• Analyze signal integrity for PAM4 and NRZ links, with eye diagrams and jitter/noise analysis.
• Apply impedance control and PCB manufacturing best practices in design guidelines.
• Document simulation methods, results, and recommendations for hardware teams.
• Demonstrate familiarity with 25G/100G/400G/800G Ethernet standards in workflows.
• Collaborate with PCB layout engineers to optimize board designs for SI/PI in data-center hardware.
