AC/DC Power Module Assembly
- Assemble and test AC-to-DC converter modules and power distribution units.
- Interpret wiring diagrams and BOMs to support efficient, high-quality builds.

Power Electronics Proficiency

Work hands-on with power conversion circuits including:
- Bridge rectifiers, buck converters, boost converters, and isolated DC/DC switching supplies
Assist in validating topologies for voltage/current regulation, efficiency, thermal performance, and protection behavior.
Familiar with operation and troubleshooting of IGBTs, MOSFETs, drivers, transformers, inductors, and other switching components.
Comfortable working with test conditions such as:
- Wide input voltages (e.g., 90–480VAC 3-phase or 100–1000VDC)
- Load transients, startup behavior, ripple, and fault responses

Circuit Troubleshooting & Test Support

Read and interpret electrical schematics, wiring diagrams, and mechanical layouts.
Troubleshoot power conversion circuits using DMMs, oscilloscopes, current probes, and other diagnostic tools.
Set up and safely operate lab equipment, including:
- Programmable DC power supplies (up to 1000V)
- 208V/480V 3-phase AC input setups
- Electronic loads, isolation transformers, and safety interlocks

Data Collection & Test Automation

Capture and log voltage, current, thermal, and other key test data from power modules under test.
Maintain organized records of test setups, procedures, anomalies, and results using spreadsheets and digital tools.
Create or modify scripts (Python, MATLAB, or LabVIEW) to automate repetitive test and measurement tasks.

Collaboration with Electrical Design Engineers

Work closely with power electronics engineers to support bring-up, validation, and debug of new power hardware.
Provide hands-on input to improve testability and manufacturability of designs.
Participate in design reviews, test plan development, and root cause analysis.

Safe Operation in High-Energy Lab Environments

Work confidently and safely with high voltage DC (up to 1000V) and three-phase 208/480VAC.
Follow established safety procedures including PPE use, arc flash protocols, and LOTO where applicable.
Contribute to continuous improvement of lab safety and reliability standards.

Skills You Bring:

Associate’s degree in Electronics, Electrical Technology, or equivalent experience (10+ years accepted in lieu of degree).
2–5+ years of hands-on experience working with high-voltage DC, three-phase AC, and switch-mode power supplies (SMPS).
Proficiency in:
- Reading electrical schematics and mechanical drawings
- Using DMMs, oscilloscopes, current probes, and electronic loads
- Setting up and configuring programmable power supplies
- Troubleshooting power electronics: rectifiers, buck/boost regulators, DC/DC converters
Familiarity with switching components like FETs, diodes, transformers, and gate drivers.
Strong organizational and documentation skills.
Basic scripting skills (Python, MATLAB, or LabVIEW) for automating lab tasks is a plus.
Precision and discipline when working around high-energy systems.
Self-starter attitude with a problem-solving mindset and a hands-on, detail-oriented approach.
Clear communicator who collaborates effectively across engineering and operations teams.
