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 transparent 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 compre
