hirify.global develops rack-scale AI infrastructure through semiconductor connectivity solutions integrating CXL, Ethernet, NVLink, PCIe, UALink, and the COSMOS software suite.

What you will do

• Architect, design, and optimize high-speed analog and mixed-signal circuits, including SerDes, PLLs, ADCs, DACs, LDOs, and bias/reference blocks.
• Define block specifications and performance, power, area, and yield trade-offs for advanced process nodes.
• Develop simulation plans across PVT, Monte Carlo, and reliability corners.
• Partner with layout designers on floorplanning, matching, parasitics, and physical implementation.
• Lead silicon bring-up, characterization, debugging, and correlation of measured results with models and specifications.
• Set technical direction, improve AMS design methodologies, contribute to IP roadmaps, and mentor design engineers.

Requirements

• MS or PhD in Electrical Engineering or a related field.
• 8+ years of experience in analog/mixed-signal integrated circuit design.
• Production-silicon experience designing high-speed AMS blocks such as SerDes, PLLs, data converters, references, or regulators.
• Strong knowledge of transistor-level design, device physics, and analog fundamentals in advanced CMOS nodes.
• Proficiency with Cadence Virtuoso, Spectre, and scripting for design automation.
• Experience taking designs from specification through tape-out and silicon validation.

Nice to have

• Experience with high-speed I/O and SerDes for PCIe, Ethernet, or UALink.
• Knowledge of physical-layer signal integrity, channel modeling, and equalization.
• Hands-on experience with high-speed measurement and characterization equipment.
• Familiarity with mixed-signal verification and analog/digital co-design.
• Strong communication skills and a collaborative, mentorship-oriented approach.

Culture & Benefits

• Hands-on technical leadership in a fast-growing AI connectivity company.
• Cross-functional collaboration with digital, system, product, packaging, and layout teams.
• Opportunity to influence AMS design methodology, IP roadmaps, and design-flow improvements.
• Discretionary bonus, incentives, and benefits may be available.
• Applications are encouraged from candidates with diverse backgrounds and experiences.
