Company

hirify.global is a well-funded startup building photonics infrastructure for AI supercomputing, including optical interconnects and scalable photonic engines.

What you will do

• Own block-level and full-chip physical implementation from RTL to GDSII for high-performance ASICs.
• Perform floorplanning, placement, clock-tree synthesis, routing, physical verification, and signoff for advanced TSMC nodes.
• Drive timing, power, and area closure in collaboration with RTL and STA teams.
• Implement multi-voltage and multi-frequency designs, hierarchical flows, physical-aware synthesis, congestion mitigation, and skew optimization.
• Perform tapeout signoff activities including PV, EM/IR, ESD, and eJobview.
• Work with RTL, STA, IP, and verification teams to resolve implementation challenges in high-speed transceiver architectures.

Requirements

• Bachelor’s or Master’s degree in Electrical Engineering, Electronics Engineering, or a related field.
• 8+ years of hands-on physical design experience, preferably with advanced technology nodes at 5nm or below.
