I/O Architect (ASIC)

Location: Bay Area, United States; on-site Monday through Friday

Company

hirify.global is an early-stage chiplet startup developing NuLink PHY technologies for high-performance, manufacturable chiplet-based systems.

What you will do

• Define NuLink PHY physical and logical/link-layer subsystems and modular bridges across PCIe, AXI4, APB, CHI, CXL, and DDR.
• Design protocol conversion layers covering transaction ordering, credit-based flow control, QoS, address translation, coherency, and memory semantics.
• Model and optimize datapath, link protocols, and CDC architectures for bandwidth, latency, power, efficiency, and signal integrity.
• Collaborate with ASIC, firmware, post-silicon, customer integration, and marketing teams while preparing architecture specifications and integration guidelines.
• Review PLL, VCO, ATB, and link-training characterization plans and create protocol testbenches for transaction handling, throughput, latency, and compliance.
• Mentor engineers, contribute to standards bodies, and improve design flows and methodologies for reliable on-time delivery.

Requirements

• 8+ years of experience in architecture definition, chip micro-architecture, protocol definition, and implementation.
• Strong knowledge of at least two connectivity protocols, including PCIe, UCIe, UALink, Ethernet, DDR, or AMBA.
• Strong scripting and automation skills.
• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or a related field.
• Expertise in RTL-to-GDSII flows, PHY implementation constraints, and practical logic design.

Nice to have

• 15+ years of ASIC architecture experience and a track record of leading teams through successful tapeouts.
• Performance modeling with C, C++, or SystemC.
• Experience with PHY clocking and floorplan guidelines.
• Exceptional problem-solving skills.

Culture & Benefits

• Fast-paced early-stage startup environment.
• Cross-functional collaboration with experienced industry specialists.
• Opportunities to work on high-volume, high-performance, manufacturable chiplet products.
• Fun work environment with excellent benefits.
