Analog Mix Signal Systems Modeling Architect

Job Title

Analog Mix Signal Systems Modeling Architect

Role Summary

Define, model, and validate mixed-signal power-delivery system architectures for AI, datacenter, and high-performance computing applications. Provide cross-functional technical leadership to translate product and customer requirements into executable system models that guide analog, digital, firmware, verification, validation, applications, and software teams.

Experience Level

Senior — requires 10+ years of relevant semiconductor or power-management system development experience.

Responsibilities

Primary responsibilities include developing executable system models, defining mixed-signal interfaces, and producing model-based evidence to inform architectural decisions and verification activities.

• Own and evolve executable mixed-signal system models for digital multiphase controllers and related power-management products.
• Define system-level behavior for sensing paths, telemetry, ADC/DAC/PWM interfaces, compensation, loop behavior, latency, quantization, noise, operating limits, and corner conditions.
• Translate product requirements and customer use cases into architectural constraints and model-based tradeoffs.
• Define mixed-signal interface contracts between systems, analog, digital, firmware, verification, validation, applications, and tools teams.
• Establish timing, accuracy, observability, and correlation expectations for analog and mixed-signal interfaces.
• Create architectural tests, reference scenarios, and model-based evidence that validate sequencing, cross-domain interactions, and system behavior before implementation.
• Collaborate with analog designers to ensure circuit-level implementation aligns with system intent without owning block-level analog closure.
• Support reusable modeling and data workflows for traceability and easier validation across product generations.

Requirements

Must-have technical skills and experience:

• 10+ years in semiconductor product development, power management, mixed-signal ICs, analog/mixed-signal architecture, or system architecture.
• Strong understanding of ADCs, DACs, amplifiers, references, sensing paths, timing circuits, PWM paths, and power stages.
• System-level modeling experience using behavioral/real-number models with MATLAB, Python, SIMPLIS, Verilog-AMS, SystemVerilog RNM, or equivalent environments.
• Ability to reason across analog, digital, firmware, validation, application, and customer-facing behavior.
• Proven ability to define testable system requirements, architectural tradeoffs, and evidence for technical decisions.

Nice-to-have:

• Experience with digital multiphase controllers, DC/DC converters, voltage regulators, or high-current datacenter power applications.
• Deep knowledge of control-loop behavior, stability, compensation, latency, quantization, noise, and model-to-silicon correlation.
• Experience with automation, scripting, data analysis, structured engineering data, or AI-assisted engineering workflows.
• Experience presenting complex cross-domain technical issues to senior technical and leadership audiences.

Education Requirements

Required: Bachelor's degree in Electrical Engineering or a related technical discipline. Preferred: Master's degree or PhD in Electrical Engineering, Power Electronics, Control Systems, Mixed-Signal Design, or a related discipline. Equivalent practical experience may be considered.
