Job Description

Avalanche Energy is seeking a lab-focused High Voltage Engineer to be the lead conductor for the High Voltage Test Cell operation supporting fusion hardware development.

Key Responsibilities

Own high-voltage projects end-to-end from concept through design, build, test, iteration, and documentation.
Operate the High Voltage Test Cell safely, including setup, readiness checks, execution, and post-test analysis.
Design and assemble DC and/or pulsed HV test circuits, instrumentation hookups, and measurement approaches for breakdown studies.
Run long-duration tests, maintain disciplined logs, and preserve data quality and repeatability across runs.
Troubleshoot flashover, arcing, conditioning behavior, contamination effects, partial discharge indications, and test setup artifacts.
Use FEM and CAD tools to support electrostatic field assessment, insulation geometry iteration, and packaging decisions, while coordinating with internal teams, vendors, and collaborators.
Write small Python scripts for experiment support and improve procedures, checklists, documentation, labeling, and build standards.

Requirements

B.S. or higher degree in Electrical Engineering, Physics, or a closely related field.
Hands-on mindset with demonstrated ability to take a project from 0 to 100 with minimal oversight.
Fundamental understanding of breakdown mechanisms in solids, liquids, gases, and vacuum, plus basic familiarity with HV testing circuits and lab best practices.
Working familiarity with COMSOL or equivalent FEM tools, SolidWorks or equivalent 3D CAD, and Python for experiment support.
Comfort running long-duration tests, maintaining disciplined experimental records, and communicating clearly with internal and external stakeholders.
Team first behavior and flexibility for test windows or lab operations that may fall outside normal business hours.
1+ years of experience working with systems above 50 kV DC.
Strong proficiency in COMSOL Multiphysics or equivalent for field stress and insulation geometry iteration.
Prior experience in experimental hardware environments with evolving requirements.
Knowledge of high-voltage transient analysis and familiarity with high-speed imaging.
