Responsibilities

Serve as a key technical interface for customer accounts, supporting power architecture and voltage regulator engagements from design through production.
Provide technical guidance on digital multiphase power controllers, power modules, and server-class power delivery solutions.
Support schematic and layout reviews, board bring-up, debug, and validation activities.
Prepare customer-facing technical materials, including program updates, validation reports, controller configuration files, issue summaries, and waveform data.
Assist customers with system validation, including voltage-regulator performance, telemetry, protection behavior, and interactions with CPU, GPU, ASIC, or SoC power domains.
Simulate voltage-regulator solutions with application-specific power distribution networks in SIMPLIS to support design reviews and reduce early risk.
Validate multiphase power solutions for datacenter and AI platforms, including transient response, efficiency, telemetry, fault behavior, and protection features.
Develop and maintain test plans, validation checklists, and coverage matrices for evaluation across operating conditions.
Use lab instrumentation and structured test methods to conduct repeatable validation.
Diagnose electrical and system issues using lab equipment and drive urgent issue resolution, including high-priority customer escalations.
Partner with design, systems, and applications teams to identify root causes and define corrective actions.
Escalate when deeper cross-functional support is needed while retaining ownership of customer communication and follow-through.
Work with Sales, Product Line, Marketing, and engineering teams to support customer engagements and design wins.
Manage multiple concurrent customer activities, including design support, validation, debug, and issue tracking.
Execute against customer milestones and internal priorities with attention to detail and responsiveness.
Identify technical risks early and drive timely action to mitigate them.
Support design adoption by applying technical expertise and practical judgment to prioritize customer and business impact.
