Our products help farmers maintain and improve crop yields while permanently removing CO₂from the atmosphere through enhanced rock weathering, delivering a dual return that conventional agricultural products cannot.\nWe produce our mineral fertilizer using spare capacity in cement rotary kilns, making it cost-competitive without building new infrastructure. Applied to soil, it releases plant-available silicon and other nutrients that strengthen crops against climate stress, drought, and pests, while sequestering carbon as the mineral dissolves.\nWith core chemistry published in Nature, our pre-seed funding secured, and key partnerships in place, we are scaling fast: moving from pilot production to a 1,000-tonne commercial run in 2027. We are looking for team members excited to unlock the power of abundant rocks towards a climate positive and food abundant future!\nPosition Details:\nWe are looking for an experienced, enthusiastic Scientist who is passionate about creating products that deliver agronomic and environmental returns.
