Geochemical Modeler

Language skills : Fluency in English, both written and oral, with excellent communication skills

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. We do this to create a liveable planet for future generations and, specifically, to regenerate soils and ecosystems, grow nutritious food, and increase food security and sovereignty in the tropics.

People-first, Performance Culture : We believe that focus on people and performance can co-exist with the right cultural vision. Our philosophy is to blend these two essential components. The Rocket symbolizes our commitment to peak performance, excellence, and reaching new heights. The Heart represents our dedication to our people, fostering empathy, compassion, and genuine care for every team member's well-being.

We are committed to diversity, equity, and inclusion. We are proud to have an internationally growing team and we are designing our people practices to serve psychological safety, belonging, and authenticity.

About the Role

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).

Key Responsibilities

1. Model Development and Refinement
   • 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
   • Parameterize and validate the model using data from column, mesocosm, and field experiments to accurately reflect the specific feedstock, soil, climate, and geographic conditions of our projects
   • Work with in-house scientists to design and execute new research experiments to understand key mechanisms of the ERW process, which can be fed into the model development
2. Simulation and Analysis
   • Conduct simulations to predict feedstock weathering rates, carbon sequestration, and the spatial and temporal transport of weathering products from soil to the ocean
   • Conduct field-scale water flux estimations to support porewater-based carbon dioxide removal (CDR) quantification
   • Analyze simulation results to understand the sensitivity of ERW performance to operational and environmental changes for optimal deployment strategy
   • Predict the impact of ERW on key environmental parameters, including soil fertility, water quality, and crop growth
3. Collaboration and Communication
   • Maintain existing and build new connections with external scientists for collaborative model development
   • Communicate model results and findings as reports and presentations to internal and external stakeholders
   • Present research findings at academic conferences and publish in peer-reviewed journals

You can be a Rock-Star if you have

Core Skills & Experience

1. Strong understanding of geochemical processes and hydrological dynamics in the soil system
2. Strong programming skills (Python or Fortran) for model development
3. Experience running models using high-performance computing resources
4. Excellent analytical and problem-solving skills
5. Strong written and verbal communication skills
6. Ability to work independently and collaboratively in a dynamic research-oriented startup environment

Key Qualities

1. PhD (or relevant experience) in Soil Science, Environmental Science, Environmental Engineering, Hydrology, Geology, Geochemistry, Earth Sciences, or a related field.
2. 3+ years of proven experience in developing, modifying, applying reactive transport, agro-ecosystem, and / or hydrological models

Bonus Points (but not essential)

1. Experience with modeling watershed-scale hydrological processes
2. Experience with modeling Enhanced Rock Weathering
