Mixed Signal Design Engineer

Job Title

Mixed Signal Design Engineer

Role Summary

The Mixed-Signal Design Engineer will design, validate, and integrate analog and mixed-signal circuits for high-speed interface integrated circuits (low-jitter buffers, SERDES, CDR) using deep-submicron process nodes (28nm and below).

Work within a product team through the full development cycle — from specification and circuit synthesis to verification and product release.

Experience Level

Mid-level — typically BSEE with 3+ years or MS/PhD with 2+ years of ASIC/mixed-signal design experience.

Responsibilities

Key responsibilities include:

• Define product requirements and translate them into circuit-level specifications.
• Synthesize and design analog and mixed-signal circuits from transistor/resistor level to system level.
• Perform simulation, modeling, validation, verification, and integration of mixed-signal ICs.
• Develop major functional blocks within larger products focused on high-speed interfaces.
• Create validation environments and analyze test results to diagnose and debug designs.
• Mentor and oversee the development of junior engineers.

Requirements

Must-have skills and experience:

• Hands-on experience with high-speed custom circuit design in deep-submicron (DSM) processes.
• Strong understanding of analog and mixed-signal circuits (amplifiers, current/voltage references, ADC/DACs) and analog-digital interfaces.
• Experience with validation environment creation, behavioral modeling, and test result analysis.
• Prior experience with one or more of the following: PLL/CDR, PI, DFE/CTLE, TX circuits.
• Good written and verbal communication skills and ability to work effectively in cross-functional teams.

Nice-to-have:

• Design experience with FinFET technologies.
• SystemVerilog/RTL behavioral coding.
• Scripting and automation (TCL, Python) and C/C++ experience.

Education Requirements

Bachelor of Science in Electrical Engineering (BSEE) with 3+ years of ASIC/mixed-signal design experience, or a Master’s/PhD with 2+ years in ASIC/mixed-signal design. (Degrees specified: BSEE, MS, PhD.)
