Job Description

Position Overview

We are looking for an experienced Staff AMS Verification Engineer to lead and execute verification of complex Analog/Mixed-Signal (AMS) PMIC (Power Management IC) designs. The role involves developing verification strategies, testbenches, methodologies, and automation for block-level and top-level PMIC verification.

The ideal candidate will have strong expertise in analog/mixed-signal verification, SystemVerilog/UVM, real-number modeling (RNM), SPICE simulations, and power-management circuits, with the ability to work closely with analog design, digital design, modeling, and product engineering teams.

Key Responsibilities

Own the AMS verification strategy for PMIC blocks and full-chip/top-level designs.

Define verification plans, coverage goals, test scenarios, and verification methodologies.

Develop and maintain SystemVerilog/UVM-based verification environments for mixed-signal designs.

Develop and use Real Number Models (RNM), behavioral models, and mixed-signal abstractions for efficient verification.

Perform AMS/DMS simulations for functional and corner-case verification.

Verify PMIC functionality including:

LDOs and voltage regulators, Buck/boost converters, Bandgap references,Oscillators, Charge pumps, Power-on-reset (POR), Brownout detection, Voltage/current monitoring, ADC/DAC interfaces, Power sequencing and state machines ,Protection features(OVP, UVP, OCP, OTP, and short-circuit protection)

Develop verification models for analog blocks and their interaction with digital control logic.

Debug failures across analog, digital, RTL, behavioral models, and testbench environments.

Collaborate closely with analog designers and digital designers, review design specifications and identify verification gaps, corner cases, and potential risks.

Mentor junior and senior verification engineers and provide technical leadership.

Drive improvements in verification methodology, simulation efficiency, automation, and coverage closure.

Contribute to project schedules, technical reviews, sign-off criteria, and verification documentation.
