Mixed-Signal Verification Engineer – Analog IP

Mixed-Signal Verification Engineer III

onsemi (Nasdaq: ON) is a global leader in intelligent power and sensing technologies, driving innovation to build a safer, cleaner, and smarter world. With a strong focus on automotive, industrial, and AI data center markets, we are shaping the future of vehicle electrification, sustainable energy, and advanced automation.

The Treo Platform is a high-performance analog and mixed-signal platform built on 65nm Bipolar-CMOS-DMOS (BCD) technology. Supporting voltages from 1–90V and operating temperatures up to 175°C, Treo enables scalable SoC solutions for automotive, medical, industrial, and AI data-center applications. Its modular analog IP is integrated into digital-on-top architectures manufactured in onsemi's 300mm East Fishkill, NY fab.

We are seeking a Mixed-Signal Verification Engineer III to verify analog and mixed-signal IP integrated into digital-on-top SoC environments on the Treo platform. This mid-level individual contributor role reports directly to the Analog Design Team Manager. You will own the development and execution of mixed-signal verification solutions, leveraging System Verilog and behavioral modeling to ensure power and clock IP meet functional and integration requirements prior to tape-out.

Key Responsibilities

• Own mixed-signal verification for assigned analog IP blocks using System Verilog and UVM-based methodologies.
• Develop scalable digital-on-top test benches incorporating behavioral models of analog IP such as PLLs, LDOs, DC/DC converters, and oscillators.
• Translate analog specifications into executable verification plans, assertions, coverage, and checkers.
• Develop and maintain behavioral models using System Verilog real-number modeling to abstract analog behavior for system-level simulation.
• Execute regressions, analyze results, and drive debug to root cause across analog, digital, and mixed-signal boundaries.
• Verify configuration, calibration, monitoring, and fault-handling interfaces between analog IP and digital logic.
• Coordinate with analog designers, digital verification, and system teams to ensure verification completeness and sign-off readiness.

Behavioral Modeling & Abstraction

• Create and refine behavioral and functional models suitable for large-scale SoC simulation while preserving key performance characteristics.
• Define modeling assumptions, limitations, and validation strategies in collaboration with analog designers.
• Contribute to abstraction and co-simulation strategies balancing accuracy, runtime, and reuse.

Tools, Flows & Quality

• Use industry-standard digital, mixed-signal, and AMS simulation tools.
• Apply coverage-driven verification practices and participate in verification reviews.
• Follow established version control, regression, and documentation practices; propose incremental flow improvements.

Collaboration & Technical Leadership

• Operate with moderate independence while mentoring junior verification engineers.
• Provide technical input during IP definition and integration reviews from a verification perspective.
• Proactively identify verification risks and communicate them clearly to stakeholders.

Minimum Qualifications

• Bachelor's or Master's degree in Electrical Engineering or related field.
• Minimum of 6 years of experience in mixed-signal or digital IC verification.
• Strong proficiency in System Verilog and UVM-based verification.
• Hands-on experience building behavioral models using Verilog-A/AMS or System Verilog real-number modeling.
• Experience verifying analog IP within digital-on-top SoC environments.

Preferred Qualifications

• Familiarity with power management or clocking architectures (BGs, PLLs, LDOs, DC/DCs).
• Experience with coverage-driven verification and assertion-based methodologies.
• Exposure to automotive or industrial silicon reliability and safety requirements.
• Interest in automation, scripting, or AI-assisted verification workflows.

Success Metrics

• High-quality, reusable mixed-signal verification environments delivered on schedule.
• Early and effective identification of functional and integration issues in analog IP.
• Reduced verification escapes at SoC and silicon bring-up stages.
• Demonstrated…
