R&D Scientist — Alkalinity & Carbonate Chemistry

You will play a key role in developing and optimizing our carbon removal technology. Working at the intersection of chemistry, geochemistry, process engineering, and climate technology, you will design experiments, build and improve laboratory and pilot scale systems, and transform scientific insights into engineering solutions.

In this role, you will:

• Design, execute, and evaluate laboratory experiments to investigate carbonate chemistry, mineral dissolution, and reaction kinetics.
• Build, operate, and optimize laboratory and pilot scale experimental setups.
• Operate, calibrate, and validate sensors and analytical instrumentation.
• Analyse experimental data using Python or similar scientific computing tools to support engineering decisions.
• Apply geochemical modelling tools such as PHREEQC, Reaktoro, or similar software.
• Collaborate closely with interdisciplinary teams to accelerate technology development.
• Document experimental work and communicate findings clearly across the team.
• Contribute to the development of technology that permanently removes CO₂ from the atmosphere.

You enjoy solving complex interdisciplinary challenges with a hands on approach.

Ideally, you have:

• A strong understanding of aqueous carbonate chemistry and the marine carbonate system.
• Knowledge of mineral dissolution processes, reaction kinetics, and mass transfer.
• Experience working with alkaline materials and their reaction kinetics in aqueous systems.
• Experience with geochemical modelling tools such as PHREEQC, Reaktoro, or similar.
• Experience planning, executing, and evaluating laboratory experiments.
• Proficiency in Python or similar scientific computing tools for data analysis.
• Excellent documentation and communication skills in English.

It is a plus if you have experience with:

• Carbon dioxide removal, Ocean Alkalinity Enhancement, Enhanced Rock Weathering, carbon capture, or related climate technologies.
• Laboratory and pilot scale process development.
• Chemical sensors and analytical instrumentation, including pH, conductivity, dissolved CO₂, alkalinity, flow, pressure, and temperature sensors.
• Sensor calibration, validation, and uncertainty analysis.
• Design of experiments and statistical data analysis.
• Process engineering concepts such as reactor design, gas liquid mass transfer, and scale up.
• Working in interdisciplinary teams or startup environments.

You are curious, analytical, and motivated by understanding why processes behave the way they do. You enjoy building and improving experimental systems, are comfortable working across laboratory experiments, pilot plants, and computational modelling, and combine scientific rigour with a pragmatic mindset. You take ownership of technical challenges and are excited to contribute to technologies that permanently remove CO₂ from the atmosphere.
