Signal Integrity / Power Integrity Engineer

Hudson River Trading is seeking a Signal Integrity / Power Integrity Engineer to join its expanding Hardware team. The role focuses on delivering high-performance PCB and package designs for advanced ASIC platforms by modeling, optimizing, and validating high-speed electrical interfaces and power-delivery networks. The engineer will collaborate with internal teams and external design partners to create robust, testable, and manufacturable designs.

Responsibilities

• Develop creative signal integrity (SI) and power integrity (PI) solutions for complex system design challenges
• Analyze and guide high-speed PCB, BGA, and advanced package designs from 28+ Gbps through the latest signaling technologies
• Run system-level SI simulations for high-speed SERDES links, and model, optimize, and validate vias, connectors, sockets, breakouts, stackups, routing, and package interfaces using 3D EM and circuit simulation tools
• Drive substrate and board-layout SI guidelines, post-layout extraction and analysis, and ongoing improvement of models and methodologies against lab measurements
• Analyze and guide power delivery for ASICs drawing 500+ amps, including static/DC and dynamic/AC analysis across the full power train — PSUs, cables, connectors, voltage regulators, PCBs, capacitor networks, packages, and dies
• Automate simulation, data gathering, analysis, and visualization workflows
• Partner with external design and layout vendors on requirements, deliverables, and tradeoffs, and collaborate with internal electrical, mechanical, package, layout, manufacturing, and validation teams throughout the lifecycle

Preferred

• PAM4 at 56/112+ Gbps is preferred
• Experience with 2.5D packages, board/package layout, or PDN evaluation is preferred
• Familiarity with lab measurement equipment, including VNAs, TDRs, and high-speed oscilloscopes is preferred
• PAM4 at 56/112+ Gbps
• 2.5D Package Experience
• Board/Package Layout
• PDN Evaluation
• Lab Measurement Equipment
• Vector Network Analyzers (VNAs)
• Time-Domain Reflectometers (TDRs)
• High-Speed Oscilloscopes

Benefits
