Technologist – Analog/Mixed Signal Design Engineer

Job Title

Technologist – Analog/Mixed Signal Design Engineer

Role Summary

Design and develop analog and mixed-signal circuits for semiconductor products used in data storage systems. Collaborate with digital designers, layout engineers, and system architects to translate specifications into manufacturable circuit blocks and support the product lifecycle from concept through production.

Experience Level

Mid-level (3+ years professional experience in analog or mixed-signal circuit design).

Responsibilities

Key responsibilities include:

• Design amplifiers, filters, oscillators, data converters, and related analog blocks.
• Perform circuit analysis and simulation using SPICE, Cadence Virtuoso, or equivalent tools.
• Conduct signal integrity, noise, and power-consumption analysis and optimization.
• Create and review schematics, design documentation, and layout guidelines for manufacturing.
• Integrate analog blocks with digital subsystems and collaborate on system-level tradeoffs.
• Validate designs with bench testing and characterization using oscilloscopes, spectrum analyzers, and other test equipment.
• Troubleshoot design issues and implement corrective actions to meet specifications.
• Participate in design reviews and provide technical feedback to improve performance and manufacturability.
• Support tape-out, silicon validation, and yield improvement activities.

Requirements

Must-have qualifications:

• 3+ years of professional experience in analog or mixed-signal circuit design.
• Proficiency with circuit simulation tools (SPICE, Cadence Virtuoso, or equivalent).
• Solid understanding of analog circuit fundamentals (amplifiers, filters, signal conditioning).
• Experience with PCB design and layout considerations for analog circuits.
• Proficiency in MATLAB, Verilog, or VHDL for verification and modeling.
• Experience using oscilloscopes, multimeters, spectrum analyzers, and similar test equipment.
• Strong analytical, problem-solving, and documentation skills; effective communicator.

Preferred / Nice-to-have:

• 5+ years in semiconductor or analog design environments and experience with mixed-signal elements such as data converters, PLLs, or power-management circuits.
• Knowledge of RF/high-frequency design, low-power techniques, and design-for-manufacturability (DFM).
• Experience with version control, collaborative design tools, tape-out, and silicon validation.
• Background in signal processing or DSP.

Education Requirements

Not specified.
