Principal Hardware Engineer - DC Hardware

Principal Hardware Engineer - DC Hardware

Background:

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).

You will play a key role in advancing power delivery architecture, focusing on fast transient response, load regulation, protection systems, thermal management, and system-level integration. This position provides the opportunity to own power-delivery modules from concept through production release, supporting advanced SoCs, high-power devices, and complex test conditions. You will collaborate closely with cross-functional teams across hardware, firmware, mechanical, and test engineering to deliver robust, high-performance solutions.

Project:

We are looking for a highly collaborative engineer with 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

Preferred 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
