Preferred * 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. ## Description 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. Equipment in scope includes liquid hydrogen storage systems, dispensing infrastructure, cryogenic components, pressure systems, PLC-based controls, and process safety equipment. You will work within a collaborative engineering team and engage with field and product stakeholders as part of your day-to-day workflow. Core Duties and 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. ## Related Videos - [Data Science, ML & AI in the Oil and Gas Industry at NDT Global - Dr. Katja Träumner](https://www.wearedevelopers.com/videos/1308-data-science-ml-ai-in-the-oil-and-gas-industry-at-ndt-global-dr-katja-traumner) - [Data Science in Retail](https://www.wearedevelopers.com/videos/586-data-science-in-retail) - [Leveraging Large Language Models for Legacy Code Translation: Challenges and Solutions](https://www.wearedevelopers.com/videos/1157-leveraging-large-language-models-for-legacy-code-translation-challenges-and-solutions) - [PySpark - Combining Machine Learning & Big Data](https://www.wearedevelopers.com/videos/44-pyspark-combining-machine-learning-big-data) - [Data Science on Software Data](https://www.wearedevelopers.com/videos/162-data-science-on-software-data) - [How Data is Shaping our Games](https://www.wearedevelopers.com/videos/176-how-data-is-shaping-our-games) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [A Guide to Green Tech and Green IT Careers](https://www.wearedevelopers.com/magazine/374-a-guide-to-green-tech-and-green-it-careers) - [Data Engineer Salary UK](https://www.wearedevelopers.com/magazine/253-data-engineer-salary-uk) - [Software Engineer Career: Things You Should Know](https://www.wearedevelopers.com/magazine/143-software-engineer-career-things-you-should-know) - [Software Engineer Salary London](https://www.wearedevelopers.com/magazine/252-software-engineer-salary-london) - [Best Countries for Software Engineers](https://www.wearedevelopers.com/magazine/267-best-countries-for-software-engineers)
