Principal Hardware Engineer - DC Power

About the role

We are seeking a Principal Hardware Engineer to join our DC Hardware team. In this role, you will design, develop, and validate high-current, high-power sourcing and switching hardware used in semiconductor automated test equipment (ATE).

Responsibilities

• Play a key role in advancing power delivery architecture, focusing on fast transient response, load regulation, protection systems, thermal management, and system-level integration.
• Own power-delivery modules from concept through production release, supporting advanced SoCs, high-power devices, and complex test conditions.
• Collaborate closely with cross-functional teams across hardware, firmware, mechanical, and test engineering to deliver robust, high-performance solutions.

Requirements

• Deep expertise in power electronics and high-current hardware design.
• Bachelor’s or Master’s degree in Electrical Engineering or related field.
• 8+ years of experience in power electronics, high-current power delivery, or instrumentation hardware design.
• Proven experience architecting and designing high-current power delivery modules (mA to 100+ A).
• Strong expertise in switching power supplies, multiphase regulators, linear regulators, and advanced power-stage topologies.
• Experience designing fast-response voltage/current sourcing circuits optimized for transient performance and dynamic load conditions.
• Deep understanding of power integrity and PDN optimization across full signal paths (instrumentation, cabling, loadboard, and DUT).
• Experience modeling and mitigating droop, overshoot, ringing, and ground bounce under fast load conditions.
• Proficiency in simulation and analysis of loop stability, compensation networks, and transient response.
• Experience designing protection systems including OCP, OVP, OTP, short-circuit protection, and fault isolation.
• Knowledge of reliability engineering, derating techniques, and thermal modeling for long-term system stability.
• Experience with high-current routing, low-impedance path design, and system-level thermal considerations.
• Proven ability to lead hardware bring-up, debug complex analog/mixed-signal systems, and drive root-cause analysis.
• Hands-on experience with lab equipment including oscilloscopes, power analyzers, current probes, and electronic loads.
• Proficiency with SPICE simulation, PDN modeling tools, and PCB design tools.
• Experience collaborating with firmware teams on control loops, telemetry, calibration, and system integration.
• Strong analytical, problem-solving, and communication skills.

Qualifications

• Experience designing power-delivery modules specifically for semiconductor ATE systems.
• Knowledge of dynamic voltage scaling, digital power control, and telemetry systems.
• Familiarity with high-current connectors, cabling, and low-impedance mechanical design principles.
• Experience with thermal modeling, heatsink design, and airflow optimization.
• Understanding of HALT/HASS, stress testing, and failure-mode analysis.
• Experience supporting system-level integration including loadboards, probecards, and DUT environments.
• Track record of contributing to design standards, best practices, or technical mentorship.
