Job Description

Company Overview

Are you excited by the potential of large-scale carbon removal? If so, Captura Corp. is seeking a Senior Scientist in Ocean Modeling to join us.

Captura is an early-stage technology start-up with the mission to develop globally scalable carbon removal to support a sustainable future for the world’s climate. Captura’s unique technology was developed and proven in Caltech’s laboratories and uses established electrochemical concepts to enable gigaton-scalable solutions for removing carbon dioxide (CO2) from the atmosphere via direct ocean capture. We capture carbon dioxide using only renewable electricity and seawater, creating no byproducts. CO2-depleted seawater is returned to the ocean to absorb CO2 that comes from the atmosphere.

As Senior Scientist in Ocean Modeling, you will work closely with Captura’s Principal Oceanographer and the MRV team. This role is critical in the validation of Captura’s technology.

Key Responsibilities:

• Lead Captura’s modeling initiatives with a strong focus on fluid dynamics and transport in coastal and open-ocean systems.
• Employ regional ocean biogeochemical models to quantify atmospheric CO₂ drawdown and evaluate ecosystem impacts .
• Develop and implement near-field fluid dynamics modeling techniques to track and predict plume behavior .
• Validate models through comparison with in situ monitoring data , ensuring accuracy and reliability.
• Create and refine modeling tools to support deployment site selection and the design of monitoring plans for future projects.
• Collaborate with the marine carbon dioxide removal MRV modeling community to share insights, best practices, and integrate new methodologies.
• Partner with internal MRV teams to align modeling efforts with project goals, timelines, and broader organizational objectives.

Educational/Experience Requirements:

• PhD in Physical or Chemical Oceanography or a closely related discipline.
• 5+ years of experience utilizing the Regional Ocean Modeling System (ROMS) or similar ocean modeling frameworks.
• Deep expertise in fluid dynamics , seawater carbonate chemistry , and coastal ocean processes .
• Demonstrated proficiency in Python, Julia , or other relevant programming languages.
• Strong analytical and problem-solving skills , with a proven track record of taking initiative and thriving in a collaborative team environment.
• Excellent communication skills , both written and verbal, to convey complex modeling results to diverse audiences.
• A passion for innovation and commitment to advancing carbon removal technology at scale.
