About the Project

The Role

While this is very much a lone ranger role, you\’ll be surrounded by the wider project team, giving you plenty of scope to influence, engage and champion positive change across all areas of delivery.

You don\’t need prior social or carbon expertise, but a strong interest in both and the ability to drive ideas and influence stakeholders is key.

• Advise and support project teams on environmental risk management, ensuring mitigations are implemented effectively
• Engage and influence subcontractors, clients, and the wider workforce to champion sustainability best practice
• Promote innovation in sustainable construction methods, materials, and processes
• Lead or support investigations into environmental incidents and drive corrective action
• Provide sustainability training, briefings, and upskilling for project staff
• Assure compliance with the LOR Environmental and Carbon Management Systems
• Develop a social value approach for the packages and engage the delivery teams

What We\’re Looking For

• Passion for sustainability and environmental best practice
• An engaging and confident communicator who can inspire teams, drive ideas forward, and influence stakeholders at every level
• Organised, proactive, and able to prioritise in a fast-paced project environment
• Experience working on infrastructure or high-risk environmental sites (preferred)
• Degree in Environmental Management, Sustainability, or related field (preferred)
• IEMA/IES/IEEM membership (practitioner level preferred)
• Be technically familiar with an extensive range of environmental processes and products, carbon data/ reporting and social value strategies (including, ISO14001, ISO50001 and PAS2080)

What\’s in it for you

• Competitive salary + car/travel allowance
• Private Medical Insurance
• Enhanced pension & parental leave
• Life, dental, and critical illness cover + income protection
• 33 days holiday (including bank holidays)
• Professional development opportunities
