About the Role
We are supporting a leading engineering contractor involved in large-scale green hydrogen and Power-to-X infrastructure across Europe. They are seeking an experienced HVAC Engineer to join the project team responsible for designing, integrating, and validating climate and ventilation systems for critical hydrogen production and storage facilities.
This role is crucial in ensuring the safe and energy-efficient operation of hydrogen equipment rooms, electrolyser halls, compressor buildings, and process enclosures.
Key Responsibilities
* Design HVAC and ventilation systems for hazardous zones (ATEX) in hydrogen plants
* Ensure compliance with hydrogen-specific safety standards (e.g. ventilation for H2 dispersion)
* Prepare heat load calculations, ducting layouts, airflow simulations, and equipment specs
* Collaborate with process, piping, and safety teams to align environmental control requirements
* Generate technical documentation: HVAC philosophy, datasheets, functional specs, and control logic
* Support installation, commissioning, and integration with BMS / SCADA systems
* Liaise with EPC contractors, suppliers, and regulatory authorities
Required Profile
* Degree in Mechanical or Building Services Engineering
* 5+ years’ experience in HVAC for industrial or process environments
* Knowledge of hydrogen safety standards, ATEX/IECEx zones, and ventilation design in explosive atmospheres
* Proficiency with design tools (e.g., Revit MEP, AutoCAD, Hevacomp, or similar)
* Strong understanding of cooling and ventilation dynamics for machinery, compressors, and electrical rooms
* Fluent in English (Dutch/German/French is a plus)
Desirable Experience
* Projects involving electrolysis, fuel cells, or gas compression
* HVAC integration into skid units or modular plant rooms
* Familiarity with PID integration, controls, and emergency ventilation design
* Experience working in FEED and EPC project phases
