**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 clear 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, including inlet/outlet conditions, flow, pressure ratio, compression stages, cooling, utilities, controls, footprint, access, maintainability, noise, vibration, installation, and performance guarantees. * Develop sizing and specification inputs for buffer vessels, pressure vessels, high-pressure storage systems, gas coolers, dryers, purifiers, separators, filters, condensate handling, and associated piping, valves, instruments, and utility systems. * Support the technical definition and integration of hydrogen delivery and downstream applications, including tube-trailer loading bays, cylinder or cascade filling, hydrogen dispensers and refueling stations, storage and export systems, and project-specific pipeline or off-taker interfaces. * Define mechanical package battery limits and interfaces with the electrolyzer, water systems, electrical supply, controls, safety systems, civil works, buildings, drainage, vents, and EPC plant design. * Review package layouts, utility loads, nozzle and connection requirements, vendor drawings, foundation loads, access and maintenance clearances, lifting requirements, and installation constraints. * Evaluate material selection and compatibility for hydrogen and utility services, considering pressure, temperature, purity, corrosion, embrittlement risk, cleanliness, and applicable project requirements. * Support technical optimization and value engineering. **Supplier RFQ, Technical Evaluation and Cost Estimation:** * Identify and prequalify suitable suppliers and package vendors * Prepare complete technical RFQ packages, including datasheets. * Manage supplier technical clarifications and quotation timelines * Prepare technical quotation evaluations, deviation lists, clarification logs, and recommendation summaries; and identify scope or pricing gaps. * Develop budgetary and basic-engineering CAPEX estimates and detailed cost breakdowns for process and mechanical BOP. * Develop and maintain Excel-based cost models and a structured cost database. * Prepare preliminary BOMs, BOQs, and MTOs * Identify cost-reduction opportunities, alternative technical solutions, and supplier strategies. **EPC Partner and Project Execution Support:** * Support EPC partner engagement during project development phase * Review relevant EPC and vendor deliverables for alignment with the agreed design basis, scope, performance requirements, and equipment interfaces. * Support technical query resolution, design reviews, interface coordination, change-impact assessment, and closure of preliminary engineering assumptions during project execution. * Participate in HAZID, HAZOP, design reviews, constructability reviews. * Provide occasional site and construction support for technical clarification, installation readiness, package interfaces, testing, and commissioning preparation; **EDUCATION AND EXPERIENCE REQUIRED :** * Bachelor's degree in Chemical Engineering, Process Engineering, Mechanical Engineering, or a closely related discipline. Post graduation in any engineering discipline is a plus. * 8-12+ years of relevant experience in process engineering, mechanical package engineering, applications engineering, within hydrogen, industrial gas, oil and gas, petrochemical, chemical, gas compression, CNG/LNG, or related industries is desired. * At least 3 years of hands-on experience in process or mechanical basic engineering, equipment sizing, cost estimation, supplier RFQs, or techno-commercial package evaluation. * Demonstrated experience with several of the following: compressors, buffer or storage vessels, pressure vessels, gas dryers/purifiers, cooling systems, high-pressure gas piping, loading systems, dispensers/refueling systems, or industrial gas utilities. * Demonstrated experience preparing engineering calculations, datasheets, RFQs, technical quotation evaluations, budgetary estimates, BOMs/BOQs/MTOs, and scope or battery-limit documents. * Experience working for an EPC contractor, engineering consultant, or hydrogen technology provider is strongly preferred. **Skills:-** Detailed Engineering, Engineering Calculations, Equipment Datasheets, Equipment Sizing, Material Selection, Piping and Instrumentation Diagrams (P&ID), Process Engineering, Process Flow Diagram (PFD) **Education: -** Bachelor of Engineering / Bachelor of Technology (B.E./B.Tech) - Chemical Engineering, Bachelor of Engineering / Bachelor of Technology (B.E./B.Tech) - Mechanical Engineering _Ohmium is an equal opportunity employer.
