HVAC Systems Engineer (Contract) Renewable Energy Sector

Overview

We are seeking an experienced HVAC Systems Engineer to join a long-term renewable energy project, working remotely with occasional site visits. The successful candidate will lead the definition, specification, and design of complete HVAC systems, providing the technical framework that underpins 3D modelling, fabrication, and installation.

This role is ideal for an engineer with strong analytical capability and a proven background in defining robust, efficient HVAC solutions within complex industrial or renewable environments.

• Define and develop complete HVAC system architectures for renewable energy facilities.

• Produce system definitions, equipment specifications, and design calculations (airflow, heat load, pressure drop).

• Determine design criteria, component sizing, and control strategies to ensure compliance with performance and safety requirements.

• Generate technical documentation and design reports, feeding into the detailed design and 3D modelling teams.

• Support the integration of HVAC systems with mechanical, electrical, and process disciplines.

• Provide technical oversight during fabrication, installation, and commissioning, ensuring systems meet defined specifications.

• Ensure compliance with industry standards and project requirements (CIBSE, ASHRAE, BS EN).

• Liaise with suppliers and contractors on component selection, performance validation, and system compatibility.

• Proven experience in HVAC systems engineering or building services design, ideally within industrial or renewable energy sectors.

• Strong capability in airflow and thermal analysis, system sizing, and specification development.

• Experience leading system-level design prior to 3D layout and detailed modelling.

• Knowledge and practical experience using Revit and ideally Cadmatic for coordination with design teams.

• Familiarity with design standards and energy efficiency regulations.

• Good understanding of 3D design outputs and how to guide teams using modelling tools.

• Degree in Mechanical Engineering, Building Services, or a related discipline.

• Chartered or working toward CEng (CIBSE or IMechE) advantageous.

• Ability to travel occasionally for site surveys, design reviews, and commissionin
