Define, validate, and standardize laboratory test procedures, equipment configurations, and experimental protocols.
Design and execute laboratory validation programs including insulation testing and analysis, electromagnetic compatibility evaluation, and cycle life testing.
Apply diagnostics, failure mode, and contingency analysis to identify root causes of performance limitations and generate technically sound corrective solutions.
Champion environmental health and safety standards within laboratory and validation environments.

Modeling, Software, & Controls

Perform modeling and simulation of power systems, transient events, protection coordination, and degradation mechanisms using MATLAB or equivalent analytical tools.
Develop and maintain engineering software tools and internal platforms in C# to support system modeling, data analysis, automation, and algorithm implementation.
Contribute to control logic development and system-level algorithm design for energy storage and distributed generation platforms.
Collaboration, Leadership & Governance
Collaborate with cross-functional engineering and manufacturing teams to translate research findings into deployable, production-ready systems.
Mentor laboratory technicians and junior engineers to ensure high quality execution and technical understanding of experimental work.
Support technical documentation, validation reporting, intellectual property development, and structured knowledge transfer processes.
Present research findings and technical recommendations to executive leadership and internal stakeholders.
Other duties as assigned.

BASIC QUALIFICATIONS (MUST-HAVE)
