Revolt is part of Anthesis, the world's leading specialist in sustainability, meaning everything we do is backed by substance and technical rigour.

We are looking for a Senior Business Consultant to join our team. This is a hands-on role for someone who is confident leading and delivering projects independently while contributing to strategic discussions and commercial growth opportunities.

Contribute to strategic discussions and support the development of client strategies, sustainability communications approaches, and project recommendations.
Ensure all deliverables meet client objectives and quality standards.
Manage project finances, including estimates, budgets, purchase orders, invoicing processes, and project profitability.
Identify opportunities to grow existing client accounts and contribute to new business opportunities.
Coordinate cross-functional teams and manage project workflows to ensure smooth and effective delivery.
Proactively identify and resolve project or client challenges.
Stay up to date with client sectors, industry developments, and market trends.

About the Company

Anthesis

Global ESG and decarbonization advisory

Anthesis is a global sustainability consultancy that helps organizations meet environmental, social, and governance (ESG) goals. It offers services in carbon strategy, sustainable finance, supply chain transparency, and net-zero decarbonization, delivered through advisory, digital tools, and educational programs. How it works: the company provides data-driven consulting, develops practical action plans, and uses software to monitor progress, enabling clients to set targets, implement decarbonization measures, and report on ESG metrics. How it differs: it combines expert advisory with digital solutions and training for a broad client base (corporations, governments, nonprofits), delivering end-to-end support from strategy to implementation rather than just recommendations. Its goal is to help clients reduce climate impact, improve resource efficiency, and advance social equity, building a more sustainable and resilient future.
