As a key driver of the DIMO Sustainability Agenda 2030, you will take ownership of the group’s environmental and social data ecosystem. Your daily focus centers on managing a sophisticated data platform, translating monthly metrics into clear visualizations that steer executive decision-making across ten diverse business sectors. You will bridge the gap between high-level strategy and operational reality by executing green initiatives across the entire conglomerate.

This role is vital because DIMO represents major global brands like Mercedes-Benz and Siemens in Sri Lanka, meaning your work directly influences how international standards are applied locally. By mastering carbon footprinting and climate risk modeling, you help transform a traditional engineering and retail giant into a resilient, future-ready enterprise that empowers local communities while meeting global compliance requirements.

This suits someone who possesses a strong analytical mindset and thrives in a multi-stakeholder environment. You should be comfortable pivoting between technical data management and cross-departmental leadership to foster a genuine culture of sustainability.
