Company

hirify.global develops semiconductor-based connectivity solutions and software for rack-scale AI infrastructure, integrating technologies such as CXL, Ethernet, NVLink, PCIe, and UALink.

What you will do

• Architect and design high-speed analog and mixed-signal circuits, including PLLs, LDOs, references, SerDes building blocks, ADCs, DACs, and clocking circuits.
• Drive circuit development from specifications and architecture through schematic design, layout supervision, and verification across PVT corners.
• Develop robust designs in advanced FinFET process nodes while balancing power, area, and performance.
• Lead silicon bring-up, characterization, debugging, and root-cause analysis with validation and product engineering teams.
• Define test plans and correlate silicon performance with design targets.
• Set analog design methodologies and review standards, collaborate across engineering functions, and mentor engineers.

Requirements

• MS or PhD in Electrical Engineering or a related field.
• 8+ years of experience in analog and mixed-signal integrated circuit design.
• Track record designing high-speed analog circuits such as PLLs, SerDes front-ends, data converters, references, or regulators in advanced CMOS or FinFET nodes.
• Strong understanding of physical-layer design, signal integrity, and high-speed I/O.
• Proficiency with industry-standard design and simulation tools such as Cadence Virtuoso and Spectre.
• Strong layout and parasitic-aware design skills.

Nice to have

• Experience taking multiple analog or mixed-signal designs through production tape-out and high-volume manufacturing.
• Expertise in PCIe, Ethernet, UALink, UCIe, and related PHY architectures.
• Experience with silicon debug, ATE test development, design-for-test techniques, mentoring, and technical design reviews.
• Excellent communication skills and a collaborative, ownership-driven mindset.

Culture & Benefits

• High-impact, hands-on work supporting AI connectivity and advanced data-center infrastructure.
• Opportunity to influence analog design methodology and technical standards.
• Collaboration with digital, physical design, systems, architecture, validation, and product engineering teams.
• Discretionary bonus, incentives, and benefits may be available.
• Commitment to diverse ideas, backgrounds, and experiences.
