Job description

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 diagnostic functions. • Define ADC interface behavior, ADC controller requirements, sampling relationships, data-valid timing, channel sequencing, calibration hooks, latency budgets, saturation behavior, quantization expectations, and error-handling requirements. • Develop executable models and emulation-oriented representations that allow system behavior to be explored before RTL and silicon are complete. • Translate system and control-loop requirements into RTL-facing specifications, fixed-point formats, datapath constraints, register behavior, firmware interfaces, and validation requirements. • Collaborate with analog design experts on ADC and sensing assumptions while focusing ownership on the digital architecture, control data path, emulation behavior, and system-level integration. • Work with firmware teams to define observability, debug access, telemetry behavior, configuration flows, and bring-up hooks needed for characterization and customer support. • Partner with verification and validation teams to define reference scenarios, pass/fail criteria, correlation expectations, coverage targets, and structured evidence for architectural decisions. • Analyze tradeoffs across loop performance, latency, noise sensitivity, resolution, dynamic range, power, area, configurability, implementation complexity, and customer-visible behavior. • Document architecture clearly for cross-functional execution teams, including assumptions, interface contracts, model behavior, limits, corner cases, and validation expectations. • Bachelor's degree in Electrical Engineering, Computer Engineering, or a related technical discipline. • 8+ years of experience in digital systems architecture, mixed-signal SoC architecture, digital signal processing, power management, control-oriented digital design, semiconductor verification, or related product development. • Strong understanding of digital signal-processing concepts, fixed-point arithmetic, sampling theory, filtering, timing, latency, quantization, saturation, and numeric precision tradeoffs. • Experience defining ADC-facing digital logic, sensor data paths, telemetry data paths, digital controllers, or control-loop support logic in a semiconductor product environment. • Ability to translate system-level requirements into RTL-facing architecture, firmware-visible behavior, emulation models, and validation-ready specifications. • Strong cross-functional communication skills, including the ability to align systems, digital design, firmware, analog, verification, validation, applications, and software/tool teams. PREFERRED QUALIFICATIONS • Master's degree or PhD in Electrical Engineering, Computer Engineering, Signal Processing, Control Systems, Power Electronics, or a related discipline. • Experience with digital power controllers, DC/DC converters, voltage regulators, power management ICs, multiphase control, or high-current datacenter power applications. • Experience with RTL architecture, SystemVerilog, Python, MATLAB, C/C++, emulation, FPGA prototyping, behavioral modeling, real-number modeling, or hardware/software co-design. • Experience with ADC controller architecture, coherent sampling, digital filtering, decimation, telemetry, protection paths, loop compensation support, or real-time control data paths. • Experience creating reusable models, reference tests, or structured engineering data that improve model-to-RTL, model-to-emulation, or model-to-silicon correlation. • Ability to work comfortably at the boundary between algorithms, hardware architecture, firmware interface definition, and silicon validation evidence.
