About The Position

Renesas is seeking an experienced Senior Staff Digital Engineer to lead verification and evidence development for control-loop features and functions in advanced digital power management products used in AI, datacenter, and high-performance computing applications. This role focuses on proving that specific control-loop features behave as intended across requirements, behavioral models, digital implementation, analog interactions, simulation, emulation, bench validation, and silicon. The successful candidate will translate feature intent into measurable test plans, define clear pass/fail criteria, develop reusable verification methods, and correlate results across engineering environments. The role requires a strong understanding of digital control loops, mixed-signal behavior, power-system dynamics, data analysis, and verification automation. The ideal candidate combines hands-on control-loop expertise with disciplined verification and the ability to identify and resolve differences between expected behavior, implementation results, and measured performance.

Requirements

Bachelor’s degree in Electrical Engineering, Computer Engineering, or a related technical discipline.
8+ years of relevant experience in digital power control, mixed-signal verification, semiconductor validation, systems engineering, power electronics, design verification, or related product development.
Strong understanding of feedback control systems, including compensation, stability, bandwidth, transient response, latency, sampling, quantization, saturation, and nonlinear behavior.
Experience verifying or validating control-loop features and functions using measurable engineering evidence.
Strong understanding of mixed-signal building blocks such as ADCs, DACs, sensing paths, amplifiers, references, timing circuits, PWM paths, and power stages.
Experience developing test plans, test scenarios, pass/fail criteria, metrics, and technical evidence for complex electronic systems.
Ability to analyze waveforms and data, isolate behavioral differences, and connect observed results to feature intent and implementation.
Ability to independently lead technically complex verification activities from requirements through final correlation and documentation.
Strong communication skills and the ability to explain complex loop behavior and verification results clearly.

Nice To Haves

Experience with digital multiphase controllers, DC/DC converters, voltage regulators, power management ICs, or high-current datacenter power applications.

Evaluate interactions between digital loop functions and analog components, including sensing paths, ADCs, DACs, references, PWM generation, timing paths, and power stages.
Produce clear verification evidence containing test conditions, configurations, metrics, plots, waveforms, results, conclusions, and identified risks.
Develop reusable automation for parameter sweeps, corner testing, waveform analysis, regression testing, and evidence generation.
Investigate discrepancies between expected feature behavior and results from simulation, emulation, bench testing, or silicon.
Collaborate with systems, analog design, digital design, firmware, design verification, validation, applications, and software/tool teams.
Identify missing requirements, test coverage, observability, or infrastructure needed to verify loop features effectively.
Document test intent, assumptions, configurations, results, limitations, and residual risks clearly for technical and leadership audiences.
Provide technical guidance and mentorship to engineers working on control-loop verification and validation.
