Company

hirify.global is a stealth-mode startup building foundational technology for performance, scalability, and resiliency in large-scale AI data center clusters.

What you will do

• Drive implementation and register-level configuration of high-speed SerDes IP blocks across custom hardware systems.
• tune CTLE, FFE, and DFE equalization settings to improve eye margin and reduce bit error rates across cable, backplane, and board-level channels.
• Lead post-silicon bring-up, characterization, and debugging of 112G and 224G PAM4 links.
• Use oscilloscopes, BERTs, pattern generators, and protocol analyzers to validate link performance and isolate failures.
• Collaborate with signal integrity, power integrity, hardware, firmware, and systems teams to correlate lab measurements with simulations and channel models.
• Develop Python-based automation for testing, measurement, characterization, link monitoring, and validation.

Requirements

• Hands-on experience bringing up and validating 56G, 112G, or 224G PAM4 links, or high-speed PCIe Gen5/Gen6 interfaces.
• Deep practical understanding of SerDes implementation, configuration, equalization, and physical-layer debugging.
• Strong knowledge of TX/RX equalization, signal integrity, jitter, eye margin, and BER.
• Advanced proficiency with high-speed laboratory equipment, including BERTs, real-time or sampling oscilloscopes, pattern generators, and protocol analyzers.
• Experience with automated, script-based testing and lab characterization, preferably using Python.
• Ability to debug issues spanning silicon, boards, cables, backplanes, firmware, and system-level interactions.

Nice to have

• Experience with 112G or 224G PAM4 links in data center, networking, switching, accelerator, or high-performance computing environments.
• Familiarity with Ethernet, PCIe, CXL, or other high-speed protocols.
• Experience with commercial SerDes IP providers or custom in-house SerDes teams.
• Exposure to channel modeling, compliance testing, and production validation flows.

Culture & Benefits

• Remote work within an organization operating across the U.S. and Canada.
• Meaningful equity, benefits, and 401(k).
• Collaborative environment emphasizing trust, integrity, respect, accountability, and shared responsibility.
• Opportunity to work with experienced builders on foundational AI data center technology.
