hirify.global provides rack-scale AI infrastructure through semiconductor-based connectivity solutions and a software suite integrating CXL, Ethernet, NVLink, PCIe, and UALink technologies.

What you will do

• Define micro-architectures and implement complex digital blocks and subsystems.
• Own block-level design from architecture through GDS and drive designs to production.
• Collaborate with verification teams on test plans, coverage closure, and complex issue debugging.
• Lead timing closure and implement Design-for-Test features for high-performance designs.
• Work with post-silicon teams on silicon bring-up, debugging, and failure analysis.
• Mentor junior engineers and improve silicon development processes.

Requirements

• Bachelor’s degree in electrical engineering or equivalent and 8+ years of hands-on experience developing complex SoC or silicon products in server, storage, or networking markets.
• Experience with architecture definition, micro-architecture, RTL coding, functional simulation, synthesis, timing closure, gate-level simulation, and DFT implementation.
• Production experience with advanced CMOS nodes of 7nm or smaller.
• Deep expertise in at least one high-speed protocol, such as PCIe, Ethernet, InfiniBand, or DDR.
• Experience integrating and verifying third-party IP, using Cadence and/or Synopsys digital design flows, and working with UVM-based verification methodologies.
• Strong cross-functional communication, self-direction, adaptability, and ability to balance multiple priorities.

Nice to have

• Experience delivering multiple high-performance designs to production in data-center environments.
• Collaboration with embedded firmware teams and understanding of firmware development constraints.
• Familiarity with embedded processor subsystems such as RISC-V or Arm.
• Contributions to design methodology, CAD automation, or design infrastructure.

Culture & Benefits
