Sector / Field: Batteries / Industry / EPC Projects (Gigafactories) – industrial buildings with high environmental constraints (dry rooms, clean utilities, high-capacity HVAC)
Location: Dunkirk, France

Context

• Development of battery gigafactories.

• Complex industrial buildings: “ultra dry” rooms, sensitive process areas, clean utilities.

• Large-capacity HVAC networks, HEPA/ULPA filtration, energy recovery, dust management, controlled atmospheres.

Main Responsibilities

1. HVAC Design and Studies

• Sizing: thermal and airflow calculations, flow and pressure loss calculations, sizing of AHUs, fans, cooling/heating coils, air treatment systems for dry rooms.

• Plans and diagrams: P&IDs, HVAC schematics, piping layouts, openings, BIM models (Revit MEP).

2. Process & Utilities Integration

• Consider thermal loads from processes (coating, mixing, calendering, assembly).

• Define technical interfaces with HVAC, sprinklers, electrical systems, automation, utilities (chillers, steam, hot water, compressed air), dry rooms and sensitive areas.

• Manage humidity control and HEPA/ULPA filtration according to process needs.

3. Technical Follow-up and Site Support

• Validation of execution studies and technical reviews (VISA).

• Respond to RFIs and handle technical discrepancies.

• Participate in FAT/SAT for AHUs, dehumidifiers, and special HVAC equipment.

• Provide technical support on site: spot checks, commissioning, performance testing, balancing.

4. Documentation and Project Management

• Draft technical specifications, datasheets, and technical notes.

• Participate in bidding processes and contractor selection.

• Track schedule, deliverables, and report to Lead Facilities Engineer.

• Conduct BIM reviews and multidisciplinary coordination.

Technical Skills

• Industrial HVAC / Facilities.

• Industrial air treatment, dry rooms, clean rooms, HEPA/ULPA filtration.

• High-capacity HVAC and large volumes, process extraction.

• HVAC control systems, automation, and monitoring.

• Balancing, commissioning, energy performance.

• Standards: EN, ISO, GMP.

• Tools: Revit MEP, AutoCAD, Carrier HAP, Trane Trace, Climawin, P&ID, Microsoft Office, SharePoint.

Specific Requirements for Gigafactories

• Mastery of ultra-low humidity constraints (negative dew point).

• Close coordination with process and dry room teams.

• Strong HSE culture on industrial sites.

Candidate Profile

• Degree in HVAC / Energy / Fluid Mechanics Engineering (INSA, ENSAM, ENSE3, Polytech, etc.).

• 3 to 10 years of experience in industrial HVAC design / clean utilities.

• Experience in demanding industrial environments: pharmaceuticals, microelectronics, fine chemicals, batteries, food, data centers.

• Professional English required.
