E-House Mechanical Engineer

Elsewedy Electric: Powering Progress, Empowering People

Job Purpose

1. Structural Design & Calculation

• **Structural Integrity:**
• Act as the Subject Matter Expert (SME) for the structural design of E-House base frames, walls, roofs, and flooring systems to support heavy electrical equipment (switchgear, transformers, VFDs).
• **Load Analysis:**
• validate complex structural calculations, including dead and live loads, wind, snow, seismic, and transit/lifting loads.
• **Lifting & Transportation:**
• validate lifting lugs design and CoG calculations, rigging plans, and transportation strategies for heavy, oversized modular units.
• **Code Compliance:**
• Ensure all structural designs comply with international standards (e.g., AISC, ASCE, IBC, Eurocodes) and project-specific requirements.

2. Cooling, Ventilation & HVAC Design

• **Thermal Management:**
• Perform precise heat load calculations factoring in electrical equipment heat dissipation, solar radiation, and extreme ambient temperatures.
• **System Sizing & Selection:**
• Design and specify industrial-grade HVAC systems, including DX units, chilled water systems, and redundant backup systems (N+1, N+2).
• **Pressurization & Filtration:**
• Design overpressure and ventilation systems to prevent the ingress of dust, moisture, and hazardous/corrosive gases into the E-House.

3. Fire Alarm & Suppression Systems

• **System Design:**
• Validate/Design and specify complete fire detection (smoke, heat, gas) and suppression systems suitable for live electrical environments (e.g., Clean Agent systems like NOVEC 1230, FM-200, or Inergen).
• **Integration:**
• Support in validating the control logic and cause-and-effect matrices for fire safety, including the automatic shutdown of HVAC systems and closure of motorized fire dampers during a fire event.
• **Compliance:**
• Ensure all fire alarm and suppression systems strictly adhere to NFPA standards (e.g., NFPA 72, NFPA 2001) and local Authority Having Jurisdiction (AHJ) requirements.

4. Cross-Functional Leadership & Project Execution

• **Coordination:**
• Collaborate seamlessly with Electrical, Layout, and Control engineers to ensure clash-free integration of mechanical systems with electrical panels and cable routing.
• **Vendor Management:**
• Evaluate vendor technical bids for steel fabrication, HVAC equipment, and fire safety systems.
• **Fabrication Support:**
• Resolve technical queries from the manufacturing floor and conduct mechanical inspections (FAT) prior to shipment.
• You're a great fit if you have:
• Bachelor’s degree in Mechanical Engineering, or a closely related discipline.
• Fluent Written and Verbal English and Arabic
• 6-8 Years' of progressive engineering experience, with at least
• 5 years
• specifically dedicated to the design of E-Houses, Packaged Substations, or offshore modular enclosures.
• Strong knowledge of 3D modeling tools (e.g., SolidWorks or Revit).
• Experience with heat load calculation software (e.g., Carrier

Hap

• , Trane TRACE).
• Deep knowledge of international codes including AISC, ASCE, AWS, ASHRAE, and NFPA.
• Expertise in steel structures, protective coating systems (C4/C5 environments), and insulation materials.
