Geochemical Modeler

• Develop and maintain an in-house model for simulating enhanced rock weathering process in the near-field (soil) and far-field (groundwater, surface water, ocean) zones based on existing reactive transport, agro-ecosystem, and hydrological models
• Conduct simulations to predict feedstock weathering rates, carbon sequestration, and the spatial and temporal transport of weathering products from soil to the ocean
• Analyze simulation results to understand the sensitivity of ERW performance to operational and environmental changes for optimal deployment strategy
• Communicate model results and findings as reports and presentations to internal and external stakeholders

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.

• PhD (or relevant experience) in Soil Science, Environmental Science, Environmental Engineering, Hydrology, Geology, Geochemistry, Earth Sciences, or a related field
• 3+ years of proven experience in developing, modifying, applying reactive transport, agro-ecosystem, and/or hydrological models
• Strong programming skills (Python or Fortran) for model development and experience running models using high-performance computing resources
• Strong understanding of geochemical processes and hydrological dynamics in the soil system with excellent analytical and problem-solving skills

• Salary expectations and our comp philosophy are openly discussed in the first interview with the goal of managing expectations fairly
• Share options to make you feel like an owner
• Home Office Budget
• Fully Remote: Join us from anywhere within the CET (- 4/5-hour time zones)
• Personal development budget
• Language Programme Monthly Allowance
• 34+ days annual leave
• The opportunity to be autonomous, make a huge difference and belong to a vision
• Occasional off-sites in Brazil
• Laptop to fuel your productivity

We are an impact-driven, remote-first, ClimateTech (CDR) startup headquartered in Germany and Brazil to reverse climate change and make tropical agriculture more regenerative, low-carbon, and sustainable. We are working with Enhanced Rock Weathering in tropical agriculture, focusing on Brazil.
