Senior Digital Mixed-Signal Power Systems Engineer

Renesas Electronics Corp.; Austin (TX); On-site; USD 140,000 - 190,000; Full time

Job summary

Renesas Electronics Corp. is seeking an experienced Staff Digital Mixed-Signal Systems Engineer to develop, model, and verify digitally implemented mixed-signal data paths for next-generation digital power management products used in AI, datacenter, and HPC applications.

This role focuses on the digital processing that connects real-world analog measurements to control-loop decisions. You will collaborate with systems, digital, firmware, verification, validation, applications, and analog design

Qualifications

• Bachelor’s degree in Electrical Engineering, Computer Engineering, or a related technical discipline.
• 5+ years of relevant experience in digital design, mixed-signal systems, 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, filtering, timing, latency, quantization, saturation, and numeric precision.
• Experience developing or verifying ADC-facing digital logic, sensor data paths, telemetry paths, digital controllers, or control-loop support functions.
• Experience translating system or feature requirements into detailed digital implementation requirements and measurable verification criteria.
• Experience with behavioral modeling, data analysis, simulation, or engineering automation using Python, MATLAB, C/C++, SystemVerilog, or similar tools.
• Ability to analyze complex behavior across digital and analog boundaries and methodically investigate differences between expected and observed results.
• Ability to collaborate effectively with systems, digital design, firmware, analog design, verification, validation, applications, and software teams.
• Strong written and verbal communication skills, including the ability to document technical behavior and present engineering results clearly.

Responsibilities

• Develop digital mixed-signal data paths for digital multiphase power controllers and related power management products.
• Design and evaluate front-end digital signal-processing functions that filter, condition, scale, decimate, observe, and route sensed voltage and current information.
• Develop requirements for ADC interfaces and controllers, including sampling relationships, data-valid timing, channel sequencing, calibration support, latency, saturation, quantization, and error handling.
• Create executable behavioral models and emulation-oriented representations that allow system and feature behavior to be evaluated before RTL and silicon are complete.
• Translate system and control-loop requirements into detailed RTL requirements, fixed-point formats, datapath behavior, register definitions, firmware interfaces, and verification criteria.
• Analyze fixed-point implementation tradeoffs involving numeric range, precision, quantization, rounding, saturation, latency, area, and implementation complexity.
• Collaborate with analog design engineers to understand ADC, sensing, reference, timing, noise, and accuracy assumptions that affect digital implementation.
• Work with firmware engineers to develop configuration, observability, debug, telemetry, and bring-up capabilities needed for characterization and customer support.
• Work with design verification and validation engineers to develop reference scenarios, measurable pass/fail criteria, correlation methods, and test coverage for assigned features.
• Analyze results from behavioral models, RTL simulations, emulation, bench testing, and silicon measurements to identify differences and support issue resolution.
• Contribute to technical tradeoff decisions involving loop performance, latency, noise sensitivity, resolution, dynamic range, power, area, configurability, and customer-visible behavior.
• Document data-path behavior, interfaces, assumptions, models, limits, corner cases, and verification expectations for cross-functional engineering teams.
• Participate in technical reviews and communicate analysis, results, implementation risks, and recommended solutions.
