If you have a proven track record of delivering complex climate and carbon projects, thrive on engaging stakeholders to spark meaningful impact, and are passionate about creating tangible sustainability outcomes, this could be the role for you.

You’ll balance big-picture vision with an eye for detail, and most importantly, share our determination to make a difference.

The role combines technical delivery with project management, business development, and client engagement—giving you the chance to become a trusted advisor while driving measurable change.

You’ll also collaborate closely with our sustainable procurement specialists and deliver training through both our consultancy services and the award-winning Supply Chain Sustainability School.

Key Responsibilities:

• Clear understanding of client – supplier – stakeholder dynamics, with experience influencing senior decision-makers.
• Proven ability to build trust, deliver honest advice, and shape effective sustainability outcomes.
• Skilled in training delivery, workshop facilitation, and public speaking.
