Digital Mixed-Signal System Architect

Renesas is a global semiconductor company delivering innovative embedded processing, analog, power, and connectivity solutions. This role supports advanced power management products for demanding compute, AI, datacenter, and infrastructure applications. Renesas is seeking an experienced Digital Mixed-Signal System Architect to define, model, and validate the digitally implemented mixed-signal data paths used in next-generation digital power management products for AI, datacenter, and high-performance computing applications. This role focuses on the digital architecture that connects real-world analog measurements to control-loop decisions: ADC interfaces, ADC controllers, front-end filtering, digital signal processing, telemetry paths, emulation models, timing behavior, fixed-point implementation, and hardware/firmware interface definition. The successful candidate will work closely with systems, digital design, firmware, verification, validation, applications, and analog design teams to translate product requirements into executable architecture, emulation-ready models, RTL-facing specifications, and silicon-validation evidence. This is not a traditional analog design role; it is a digital systems architecture role for mixed-signal power products. WHY THIS ROLE MATTERS Own the digital mixed-signal architecture between sensed power-rail behavior and control-loop action. Define reusable front-end DSP, ADC-control, emulation, and observability patterns for advanced digital power products. Help product teams converge faster by making mixed-signal behavior executable, measurable, and traceable from model to RTL to silicon. KEY RESPONSIBILITIES Define digital mixed-signal system architecture for digital multiphase power controllers and related power management products. Architect front-end digital signal-processing paths used to filter, condition, scale, decimate, observe, and route sensed voltage and current information into control-loop, telemetry, protection, and diag
