Principal Analog Mixed-Signal Design Engineer

The role

You will architect and design high-performance analog and mixed-signal circuits including PLLs, LDOs, and high-speed SerDes building blocks. You will own designs from concept through silicon bring-up and mentor engineers.

What you will do

• Architect and design high-speed analog and mixed-signal circuits including PLLs, LDOs, references, high-speed SerDes building blocks, ADCs/DACs, and clocking.
• Drive circuit design from specification and architecture through schematic, layout supervision, and verification across PVT corners.
• Develop robust designs in advanced FinFET process nodes.
• Lead silicon bring-up, characterization, and debug.
• Define and execute test plans to correlate silicon performance against design targets.
• Set analog design methodology, review standards, and best practices across the team.
• Partner cross-functionally with digital, physical design, systems, and architecture teams.
• Mentor and guide junior engineers.

Required qualifications

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

Nice to have

• Experience taking multiple analog/mixed-signal designs through full production tape-out and high-volume manufacturing.
• Expertise in high-speed serial link design (PCIe, Ethernet, UALink, UCIe) and associated PHY architectures.
• Familiarity with silicon debug, ATE test development, and design-for-test techniques.
• Experience mentoring engineers and leading technical design reviews.
• Excellent communication skills and a collaborative, ownership-driven mindset.
