Analog/Mixed-Signal Design Engineer, Principal

Job Title

Analog/Mixed-Signal Design Engineer, Principal

Role Summary

Design and architect high-speed analog and mixed-signal circuits for photonic transceivers and electronic ICs (EICs) targeting 50G/100G optical links. Work on system-level partitioning and collaborate with photonics, digital, packaging, and validation teams to deliver scalable, low-power, high-performance EICs for optical compute and interconnects.

Experience Level

Senior / Principal — typically 10+ years of analog/mixed-signal (AMS) design experience.

Responsibilities

Primary responsibilities include system- and transistor-level design, verification planning, and enabling production test for AMS circuits used in optical links.

• Perform top-down architectural analysis of AMS systems and translate system requirements into circuit specifications.
• Analyze digital and photonic subsystem requirements and define their impact on AMS partitioning and performance.
• Evaluate and select high-performance analog topologies to meet noise, linearity, power, and area targets.
• Apply digitally assisted analog techniques to enhance system performance.
• Conduct transistor-level feasibility studies and iterate circuit designs.
• Define design specifications, verification plans, and production/bench-level test plans.

Requirements

Concise list of required and preferred technical skills and experience.

• Must-have: 10+ years AMS design experience; hands-on experience with high-speed AMS circuits such as PLLs/DLLs, ADCs, regulators, amplifiers, TX/RX, and CDRs.
• Must-have: Strong expertise in ultra-low-power analog design, digitally assisted analog circuits, and high-speed architecture trade-offs.
• Must-have: Proficiency in MATLAB/Simulink and Verilog-A modeling; familiarity with AMS design flows, chip assembly, and production test practices.
• Must-have: Experience working with layout, verification, and production test engineers; strong written and verbal communication skills for cross-domain collaboration.
• Nice-to-have: Background collaborating with photonics, AI/ML system teams, or packaging engineers; experience targeting optical transceiver EICs.
• Compliance: Ability to meet export-control eligibility requirements where applicable.

Education Requirements

Master's degree or PhD in a related area of expertise (as stated in the posting).
