Job Description:
Process and Mechanical Basic Engineering:
Develop concept- and basic-engineering deliverables for hydrogen production facilities, including design basis documents, operating cases, process descriptions, process flow diagrams, preliminary heat and material balances, utility summaries, equipment lists, line lists, P&IDs;, equipment datasheets, and process/mechanical scope documents.
Develop, maintain, and independently use auditable Excel-based engineering models for preliminary calculations, with explicit assumptions, units, input/output separation, error checks, sensitivity cases, revision control, and calculation notes.
Perform first-principles and spreadsheet-based calculations for gas-flow conversion, mass balance, preliminary compressor duty and power, buffer and storage capacity, filling cycles, pressure drop, cooling duty, utility consumption, vent/drain loads, and other concept- and basic-engineering requirements.
Define process conditions, design pressures and temperatures, turndown and operating scenarios, utilities, control interfaces, tie-ins,



battery limits, and project-specific design assumptions.
Prepare preliminary equipment sizing and selection inputs and establish the technical basis required for supplier quotations and EPC pricing.
Review and challenge calculations, simulations, datasheets, and design inputs received from Applications Engineering, EPC contractors, consultants, and vendors.
Recognize the limits of preliminary calculations and identify when specialist simulation, dynamic analysis, detailed stress analysis, safety studies, or third-party validation is required.
Identify process and mechanical integration risks related to pressure, temperature, flow, materials compatibility, water quality, drainage, venting, relief, control philosophy, start-up, shutdown, and abnormal operating scenarios.
Hydrogen Downstream Systems and Mechanical Packages:
Define technical and interface requirements for hydrogen compression packages, incl
