We are seeking a highly skilled and motivated Geochemical Modeler to join our team. You will play a crucial role in developing and refining our in-house model to simulate the enhanced rock weathering (ERW) process from the soil to the ocean. This role will involve modifying, incorporating and improving existing reactive transport, agro-ecosystem, and hydrological models to accurately predict weathering rates, carbon sequestration, and environmental impacts of ERW specific to Brazilian conditions.
The Impact you can make
Your work will directly inform company-level business decisions, translate into tangible advancements in our ERW technology, drive the optimization of our carbon capture processes, and contribute significantly to our ability to scale impactful climate solutions.
Core working relationships
You will lead the development of the in-house model, but also work closely with the rest of the Science team to advance our understanding of the ERW process in the field & model improvements. You will report to our Geochemical Modelling and Data Analysis Lead (Junyao) and work closely with our Head of Science & Research (Christina), Head of Carbon (Matthew) and our Data Analyst (Veronica).

InPlanet is a leading ClimateTech start-up pioneering Enhanced Rock Weathering (ERW) as a measurable, scalable, and verified carbon removal solution. As the first company in the world to independently certify ERW carbon credits, InPlanet ensures high-quality, permanent CO₂ sequestration while regenerating tropical soils. Backed by Stripe, Shopify, and top climate investors, InPlanet helps companies the world over achieve net zero by removing CO₂ at gigaton scale.
🌱 Empowering Farmers, Restoring Ecosystems By applying finely ground silicate rock to tropical farmlands, farmers capture and store CO₂ while improving soil health, boosting crop yields, and reducing reliance on chemical fertilizers. This regenerative approach enhances soil fertility, water retention, and nutrient availability, making farms more resilient to climate change. InPlanet supports farmers ensuring they benefit economically and environmentally while driving global carbon removal efforts.
🧪 A Science-Backed, Scalable Solution Enhanced Rock Weathering is a natural process where silicate rocks react with CO₂, forming stable bicarbonates that store carbon for millennia. By applying rock powders to farmland, InPlanet accelerates this process, delivering verified carbon removal, healthier soils, and more sustainable agriculture.
🚀 Built by Climate Experts, Driven by Impact Founded by Felix Harteneck (CEO) and Niklas Kluger (COO), InPlanet is powered by a multidisciplinary team of scientists, engineers, and climate experts committed to scaling nature-based solutions.
👉 Join the Movement As demand for permanent carbon removal grows, InPlanet is making nature-based CDR a reality. We collaborate with farmers, scientists, policymakers, and businesses to build a sustainable future where climate action and agriculture go hand in hand.
