Job description

About onsemi 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. About the Treo Platform 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. About the Role 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 SystemVerilog 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 SystemVerilog and UVM‑based methodologies. • Develop scalable digital‑on‑top testbenches 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 SystemVerilog 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 SystemVerilog and UVM‑based verification. • Hands‑on experience building behavioral models using Verilog‑A/AMS or SystemVerilog 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 technical growth and mentoring contribution within the verification team.
