• Comprehensive benefits package.

• Opportunity to engineer specialist HVAC systems for technically challenging industrial applications.

• Exposure to offshore, onshore, hazardous-area, and mission-critical engineering projects.

• Collaboration with engineering, manufacturing, fabrication, and commissioning teams.

• Travel requirements of up to 10%.

Project Engineer / HVAC Engineer / Mechanical Engineer Responsibilities

• Design complex industrial HVAC systems, including heating, cooling, ventilation, pressurisation, filtration, and air distribution for offshore and onshore applications.

• Perform detailed HVAC engineering calculations, including heat loads, cooling and heating requirements, airflow, duct sizing, pressure losses, and noise calculations.

• Undertake sizing and selection of HVAC components, including compressors, cooling and heating coils, fans, filtration equipment, and associated mechanical accessories.

• Develop detailed mechanical designs for custom-fabricated HVAC equipment, packaged systems, skids, and industrial mechanical assemblies.

• Produce conceptual layouts, general arrangement drawings, 3D models, fabrication drawings, and detailed mechanical engineering documentation.

• Review and interpret engineering proposals, customer specifications, technical requirements, and applicable industry codes to develop compliant HVAC system designs.

• Design ductwork systems, including routing, airflow distribution, pressure control, and associated mechanical arrangements.

• Develop HVAC operating sequences and control philosophies, coordinating with electrical designers on power distribution, instrumentation, and PLC-based controls.

• Perform mechanical calculations for equipment weights, centres of gravity, and structural support requirements for packaged equipment and skids.

• Work closely with project managers, client engineering teams, vendors, and fabrication personnel to deliver designs within project scope, budget, and schedule.

• Prepare technical specifications, equipment Bills of Materials, vendor enquiries, and engineering documentation required for procurement and manufacturing.

• Review engineering drawings and documentation to ensure compliance with customer requirements and applicable engineering standards.

• Provide technical support during manufacturing, equipment testing, troubleshooting, installation, and commissioning.

• Participate in technical design reviews, evaluating equipment reliability, manufacturability, constructability, and serviceability.

• Support continuous improvements in HVAC equipment design, product performance, manufacturing efficiency, and engineering processes.

Project Engineer / HVAC Engineer / Mechanical Engineer Requirements

• Engineering degree required, preferably in Mechanical Engineering or a related discipline.

• Minimum of 4 years' relevant engineering design experience, ideally involving industrial HVAC systems, custom mechanical equipment, or packaged HVAC solutions.

• Strong technical knowledge of HVAC system design, including heat load calculations, airflow requirements, ductwork design, and mechanical equipment selection.

• Experience designing HVAC equipment for industrial, offshore, oil & gas, hazardous, or classified environments.

• Understanding of direct expansion (DX) and chilled water systems, refrigeration cycles, compressors, fans, coils, and associated HVAC components.

• Experience developing detailed mechanical drawings, fabrication documentation, and 3D CAD models for custom-engineered equipment.
