Machine Learning Engineer

We built Neutreeno to transform business at speed and scale by revolutionising decarbonisation. Our software, backed by science from the University of Cambridge, helps companies understand and reduce emissions by mapping resource and emissions flow data to identify the most impactful areas for reduction. Our work with sustainability scientists from the IPCC and IEA informs international climate policy, and our approach has been adopted by leading companies. We recently completed a $5M seed round led by US investors and have been covered by ESGPost, YahooFinance, and BusinessWeekly, with a Cambridge Institute for Sustainability Leadership Earthshot Prize nomination for 2025. We are ready to grow and tap into a $130B addressable market.

About Neutreeno We built Neutreeno to transform business at speed and scale by revolutionising decarbonisation. Our software, backed by cutting-edge Cambridge science, helps companies understand and reduce emissions through data-driven insights. We work with leading sustainability scientists shaping climate policy and are expanding rapidly.

Join us in revolutionising decarbonisation and tapping into the $130B addressable market.

As a Machine Learning Engineer at Neutreeno, you’ll lead the development of intelligent systems that power our emissions and decarbonisation capabilities. You’ll build platforms that transform complex data into actionable insights for thousands of companies globally, developing AI-driven climate tech that processes vast unstructured data to reveal patterns in global emissions. You’ll collaborate with the climate science team to translate research into production-ready ML solutions, leveraging graph-structured emissions models to understand complex supply chain relationships. You’ll engage with technical stakeholders across industries to build scalable ML systems that drive decarbonisation at global scale.
