Company

Global test and automation specialists powering next-generation technologies through sophisticated semiconductor test solutions.

What you will do

• Architect and design high-current power delivery modules (mA to 100+ A) for ATE systems.
• Develop fast-response voltage/current sourcing circuits and advanced power-stage topologies (buck, multiphase, linear, hybrid).
• Optimize power integrity across the full PDN and mitigate droop, overshoot, and ringing under fast load steps.
• Design robust protection systems including OCP, OVP, OTP, and fault-isolation mechanisms to protect sensitive DUTs.
• Lead bring-up and validation of power-delivery modules using high-bandwidth scopes and power analyzers.
• Collaborate with firmware and mechanical teams on control loops, telemetry, and thermal interface design.

Requirements

• 12+ years of experience in power electronics, high-current power delivery, or instrumentation hardware design.
• Strong expertise in switching power supplies, multiphase regulators, and power-stage design.
• Proficiency with SPICE simulation, PDN modeling tools, and PCB design tools.
• Hands-on experience with high-current test setups and power measurement equipment.
• Must be based in Tualatin, OR, US
• Bachelor’s or Master’s degree in Electrical Engineering or a related field.

Nice to have

• Experience designing power-delivery modules specifically for ATE instrumentation.
• Knowledge of dynamic voltage scaling, digital power control, and telemetry systems.
• Familiarity with high-current connectors, cabling, and low-impedance mechanical design.
• Understanding of thermal modeling, heatsink design, and system-level thermal constraints.

Culture & Benefits

• Comprehensive health programs including medical, dental, and vision insurance.
• Financial security via retirement savings plans and life/disability insurance.
• Flexible Spending Accounts (FSA) and tuition assistance programs.
• Paid vacation and holidays.
• Inclusive work environment focused on diversity of thought and innovation.
