Signal Integrity​/Power Integrity Engineer

Position: Signal Integrity / Power Integrity Engineer
Location: New York

Hudson River Trading (HRT) is seeking a Signal Integrity / Power Integrity Engineer to join our expanding Hardware team. In this role, you will help deliver high-performance PCB and package designs for advanced ASIC platforms. You will apply deep expertise in signal and power integrity to solve complex system-level challenges spanning high-speed SERDES channels, high-current power-delivery networks, packages, PCBs, and supporting infrastructure.

You will work in a dynamic, cross-functional environment to model, optimize, and validate critical electrical interfaces. Partnering closely with hardware engineers and outside design partners, you will translate electrical requirements into timely, performant, 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

Qualifications MS or PhD in Electrical Engineering, Computer Engineering, Physics, or a related field, or equivalent practical experience

Experience in signal integrity, power integrity, or both for high-performance electronic systems

Strong fundamentals in electromagnetics, transmission lines, and PCB/package design

Experience with high-speed SERDES links, including at least 28+ Gbps signaling; PAM4 at 56/112+ Gbps is preferred

Experience with high-current (500 amp) ASIC power supply design

Proficiency with SI/PI CAE and circuit-simulation tools

Experience with relevant SI/PI tools such as HFSS, SIwave, Clarity 3D, Sigrity, ADS, SPICE, SIMPLIS, or MATLABPython programming or scripting automation experience for analysis, validation, or debugging

Ability to translate analysis results into robust, manufacturable PCB and package designs

Strong collaboration and communication skills, including experience working with external design partners

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

The estimated base salary range for this position is $200,000 to $300,000 USD per year (or local equivalent). The base pay offered may vary depending on multiple individualized factors, including location, job-related knowledge, skills, and experience. This role will also be eligible for discretionary performance-based bonuses and a competitive benefits package.
