Analog/Mixed Signal IC Design Engineer

Job Title

Analog/Mixed Signal IC Design Engineer

Role Summary

Join a data center infrastructure team designing and verifying high-speed analog/mixed-signal circuits for next-generation optical interconnect and high-speed memory tester products. Work targets data rates up to 224 Gbps for NRZ, PAM4, LPO, and CPO optical applications and high-bandwidth memory tester applications.

The role covers circuit design, mixed-signal simulation, pre-tapeout verification, lab characterization, and collaboration with layout, test, digital, and applications teams to deliver products from concept through production.

Experience Level

Mid-level (Experienced). The posting is listed as an experienced role; no specific years-of-experience requirement is given.

Responsibilities

Primary responsibilities include design, verification, simulation, and lab support for high-speed analog/mixed-signal IP and systems.

• Design and verify analog/mixed-signal blocks such as CDRs, PLLs, high-speed samplers, TIAs, equalizers (CTLE), VGAs, and output drivers for NRZ, PAM4, LPO, and CPO applications up to 224 Gbps.
• Design and verify high-speed mixed-signal circuits for HBM memory tester applications.
• Develop behavioral models of CDR/PLLs to inform architecture and block-level requirements.
• Run block-level and top-level mixed-signal simulations and pre-tapeout verification to confirm performance, power, reliability, and timing.
• Define production and bench-level test plans and work with lab engineers to take and analyze measurements for IP validation, yield analysis, and bug fixes.
• Participate in design reviews and collaborate with senior engineers, digital design, layout, test, and applications teams.

Requirements

Must-have and preferred technical skills, excluding formal degree requirements (see Education Requirements).

• Basic understanding of CDR and PLL architectures and specifications.
• Exposure to mixed-signal simulation tools and flows (for example: Cadence Spectre, AMS Designer) through coursework, internships, or project work.
• Familiarity with Cadence design and verification tools (Virtuoso, Spectre) is preferred.
• Familiarity with layout techniques for high-speed circuits is a plus.
• Experience with high-power DC-DC buck converter design for data center applications is a plus.
• Strong analytical and problem-solving skills; effective interpersonal and communication skills; ability to work in cross-functional teams.
• Willingness to travel approximately 10% of the time.

Education Requirements

Master of Science in Electrical Engineering (M.S.E.E.) with focus on analog/mixed-signal IC design, or Bachelor of Science in Electrical Engineering (B.S.E.E.) with a relevant graduation project. Coursework or project experience in analog/mixed-signal IC design in deep sub-micron CMOS technologies is expected; internship or practical lab experience is beneficial.
