Digital Mixed-Signal System Architect

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.

Qualifications :

• Bachelors 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

• Masters 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.
