Company

hirify.global Systems develops large-scale AI compute hardware and high-performance accelerator systems.

What you will do

• Solve signal integrity and power integrity problems for high-speed AI compute platforms, including chip-to-chip and chip-to-board interfaces.
• Perform pre-layout and post-layout SI/PI analysis across PCBs, flex circuits, rigid-flex assemblies, connectors, and advanced packages.
• Lead root-cause analysis of margin shortfalls, impedance discontinuities, coupling, resonances, and simulation-to-hardware mismatches.
• Analyze power delivery networks using DC and AC simulations, then correlate results with hardware behavior.
• Define PCB, rigid-flex, and flex stack-ups, materials, and impedance structures to meet performance targets.
• Collaborate with silicon and package design teams and act as the technical escalation point for complex SI/PI issues.

Requirements

• Master’s degree in Electrical Engineering.
• 15+ years of experience in system-level signal integrity and power integrity engineering for high-speed hardware systems.
