Sr Digital Engineer

Description

The company makes advanced digital power management products for AI, datacenter, and high-performance computing applications.

This role verifies that specific digital control-loop features behave as intended across behavioral models, digital implementation, analog interactions, simulation, emulation, bench validation, and silicon.

You will turn feature requirements into measurable test scenarios, run verification plans, analyze the results, and help correlate behavior across engineering environments. The work calls for a solid grasp of digital control loops, mixed-signal systems, power-system behavior, data analysis, and verification automation.

The team values hands-on engineering experience, disciplined verification habits, and the ability to find out why expected behavior, implementation results, and measured performance differ.

Why the role matters: it produces clear, repeatable evidence that control-loop features work as intended, connects requirements, models, tests, and measurements to raise confidence in implementation, catches feature-level issues and unexpected interactions early, and builds reusable test methods that cut repeated manual work.

Responsibilities

• Build and run verification plans for digital control-loop features and functions.
• Convert feature requirements and system intent into measurable test scenarios with pass/fail criteria.
• Check control-loop behavior across operating conditions, configurations, limits, sequencing, and corner cases.
• Write tests for compensation, stability, bandwidth, transient response, latency, sampling, quantization, saturation, mode transitions, sensing, telemetry, protection, and feature interactions.
• Analyze behavior using behavioral models, RTL and analog/mixed-signal simulation, emulation, bench measurements, and silicon results, as applicable.
• Correlate results across models, simulation, emulation, bench, and silicon to find differences and support engineering decisions.
• Assess how digital loop functions interact with analog parts such as sensing paths, ADCs, DACs, references, PWM generation, timing paths, and power stages.
• Produce verification evidence covering test conditions, configurations, metrics, plots, waveforms, results, and conclusions.
• Build and maintain automation for parameter sweeps, corner testing, waveform analysis, regression, and verification reporting.
• Investigate gaps between expected feature behavior and results from simulation, emulation, bench, or silicon.
• Work with systems, analog, digital, firmware, design verification, validation, applications, and software/tool teams.
• Flag missing requirements, test coverage, observability, or infrastructure that could block effective verification.
• Document test intent, assumptions, configurations, results, limitations, and risks clearly.

Requirements

• Bachelor's degree in electrical engineering, computer engineering, or a related technical field.
• At least 5 years of relevant experience in digital power control, mixed-signal verification, semiconductor validation, systems engineering, power electronics, design verification, or related product development.
• Solid grasp of feedback control, including compensation, stability, bandwidth, transient response, latency, sampling, quantization, saturation, and nonlinear behavior.
• Experience testing or verifying digital control functions, mixed-signal systems, power-management features, or other complex electronics.
• Understanding of mixed-signal blocks such as ADCs, DACs, sensing paths, amplifiers, references, timing circuits, PWM paths, and power stages.
• Experience writing and running test plans, test scenarios, and pass/fail criteria that produce measurable results.
• Ability to analyze waveforms and data, isolate behavioral differences, and tie observations to feature requirements and implementation.
• Experience scripting or programming for test automation, data analysis, or verification infrastructure.
• Ability to work effectively across systems, analog, digital, firmware, verification, validation, applications, and software/tool disciplines.
• Strong written and verbal communication, including explaining technical results clearly.
• Preferred: experience with digital multiphase controllers, DC/DC converters, voltage regulators, power management ICs, or high-current datacenter power applications.
• Preferred: experience verifying digital compensation, current balancing, current estimation, adaptive control, transient enhancement, telemetry, protection, or other loop-related features.
• Preferred: experience with behavioral modeling, model correlation, real-number modeling, Verilog-AMS, SystemVerilog RNM, MATLAB, Python, SIMPLIS, or equivalent tools.
• Preferred: experience with RTL simulation, mixed-signal simulation, bench automation, or semiconductor validation.
• Preferred: experience automating parameter sweeps, corner testing, waveform analysis, regression, or verification reporting.
• Preferred: familiarity with Bode analysis, gain and phase margin, load-transient testing, output-impedance analysis, timing and latency measurements, and power-system measurement techniques.
• Preferred: familiarity with structured test results, dashboards, databases, or API-driven engineering workflows.
• Preferred: experience debugging differences among feature specifications, behavioral models, RTL, bench results, and silicon measurements.
