Sr. Engineer, Analog Mixed-Signal Design

Job Title

Sr. Engineer, Analog Mixed-Signal Design

Role Summary

The Sr. Analog Mixed-Signal Design Engineer designs precision timing analog and mixed-signal circuits based on MEMS technology for networking, communications infrastructure, and ultra-low-power mobile platforms. The role focuses on schematic- and post-layout verification, chip bring-up and characterization, and cross-functional integration with layout, product, test, and characterization teams.

Experience Level

Senior — see Education Requirements for specific degree-and-experience combinations.

Responsibilities

Design, verify, and validate analog and mixed-signal blocks and support chip integration and evaluation.

• Design analog and mixed-signal circuits to meet architectural and technical specifications.
• Contribute to architectural definition and chip integration decisions.
• Perform calculations and verification simulations at schematic level and after post-layout extraction, including DFT/DFM considerations.
• Work with layout engineers to validate layouts using best-known methods.
• Document block designs and lead preliminary and final design review meetings.
• Participate in chip bring-up, evaluation, and characterization for owned blocks.
• Collaborate with Product, Characterization, Test, and Applications teams to resolve circuit issues.
• Support additional projects as assigned by management.

Requirements

Technical must-haves and preferred skills.

Must-have:

• Detailed knowledge of CMOS circuits and noise analysis.
• Expertise in at least one area: integer-N/fractional-N PLLs (Sigma-Delta and LC), Sigma-Delta ADCs (preferably >14 ENOB), temperature sensors, analog/digital filters, quartz or MEMS oscillators, sub-threshold circuits, low-noise regulators/bandgaps, or high-speed output drivers.
• Proficiency with Cadence analog design tools and simulation flows.
• Experience with MATLAB and Verilog-A; familiarity with Oceanscript is a plus.
• Ability to oversee circuit layout for critical blocks and perform noise analysis.
• Hands-on participation in chip bring-up, evaluation, and characterization.

Nice-to-have:

• Published research and silicon-proven prototypes.
• Strong written and verbal communication skills and ability to work in fast-paced teams.
• Self-starter with a strong commitment to execution and detail.

Education Requirements

M.S. in Electrical Engineering or a related field with a minimum of 4 years of related experience, or Ph.D. in Electrical Engineering with a minimum of 2 years of related experience. Excellent academic record and demonstrated research with prototypes proven in silicon are preferred.
