Company

hirify.global develops photonics-based interconnect and AI data center infrastructure, including 3D-stacked photonics engines for large-scale AI and HPC workloads.

What you will do

• Drive static timing analysis signoff for silicon photonics chips across multiple technology nodes.
• Develop timing constraints and incorporate signoff corners, margins, and derates into timing analysis flows.
• Collaborate with architecture, RTL, DFT, and methodology teams on timing modes, constraints, synthesis, place-and-route, and chip signoff flows.
• Analyze power, performance, and area tradeoffs and integrate them into chip implementation flows.
• Run full-chip STA and project timing summaries across multiple scenarios.
• Automate timing ECO generation with Tempus or PrimeTime and document implementation best practices.

Requirements

• Bachelor’s degree in Electrical Engineering or Computer Engineering.
• 12 years of physical design experience, including at least 5 years of hands-on ASIC STA, timing constraints development, and timing closure.
• Experience with Cadence or Synopsys tools, on-chip variation derates, multi-mode multi-corner constraints, and clock tree building strategies.
• Proficiency in scripting with TCL and Python, Perl, or Shell.
• Strong problem-solving, technical analysis, collaboration, and communication skills.
• Capacity to comply with federally mandated U.S. export control requirements.

Nice to have

• Master’s degree in Electrical Engineering or Computer Engineering.
• At least 8 years of hands-on ASIC STA and timing constraints development and timing closure experience with Cadence or Synopsys tools.
