About the Role

The Systems Engineer will support the reliability, performance, and continuous improvement of Plug Power’s hydrogen fueling infrastructure products. Efficiency analysis is the core of this role — mass and energy balance, ROI modeling, and test validation — supported by process sustaining work in change control, documentation, and operational requirements management. The work spans thermodynamics, process controls, and systems data as applied to GenFuel infrastructure deployed across 300+ customer sites.

Responsibilities

Analyze hydrogen system efficiency across the installed base using mass and energy balance modeling, quantifying losses, identifying degradation trends, and investigating thermal and flow capacity behavior.
Build and defend ROI analyses to support engineering change decisions, retrofit programs, and product improvement initiatives.
Develop and validate test conditions for system-level diagnostics including pass/fail criteria definition, methodology documentation, and data-driven results verification.
Define, document, and maintain system-level requirements and functional specifications for GenFuel components and assemblies.
Own process documentation integrity across GenFuel systems, maintaining cause & effect matrices, alarm testing procedures, and control narratives.
Execute and enforce the MOC process for all design and field changes, ensuring proper assessment, approval, and stakeholder communication.
Contribute to cross-functional projects as part of a broader engineering team spanning operations, field, and design disciplines.

Requirements

Bachelor’s degree in chemical, mechanical, or controls engineering or closely related field.
0–5 years of engineering experience.
Demonstrated ability to develop mass and energy balance models and apply them to real system performance problems.
Demonstrated ability to build quantitative analyses — ROI models, efficiency calculations, or test condition development from first principles.
Proficiency with data analysis tools (Python, MATLAB, Excel-based modeling, or similar) to process operational datasets and support engineering conclusions.
Ability to read and interpret P&ID drawings and apply them to system troubleshooting and change analysis.
Familiarity with process controls concepts, instrumentation, or sensor-based systems.
Clear written and verbal communication skills; able to present technical findings to both engineering and non-engineering audiences.
Self-directed and organized; capable of managing workstreams independently in a remote environment.
Experience with hydrogen, electrolyzers, fuel cells or other electrochemical or cryogenic systems.
Familiarity with SCADA, PLC-based controls, or industrial instrumentation.
Familiarity with HAZOP and LOPA methodology as applied to process safety analysis.
