Job Description
Ephemeral's mission is to restore our planet's climate and ocean. We do this by harnessing the ocean's natural ability to absorb and store carbon. By spreading alkaline minerals in shallow ocean regions, we can remove gigatons of CO2 while simultaneously countering ocean acidification.
About the position We are seeking a Coastal Modeler to help develop our Coastal Enhanced Weathering/Ocean Alkalinity Enhancement (OAE) methods, models, and projects for marine Carbon Dioxide Removal (mCDR).
By modeling systems ranging from porewaters to coastal sediment and hydrodynamic systems, you'll develop and run models which allow us to select sites, design deployments, and ultimately quantify carbon removal. Your modeling will also be fundamental to the development of our monitoring plans, and you'll play a key role in developing our site selection and MRV strategy.
As the Coastal Ocean Modeler, you will operate with a high degree of independence, taking the lead on projects and sharing your findings with the larger team. Working closely with other scientists, project developers, MRV partners, and academic collaborators, you'll be part of a team turning the promise of OAE as a scalable, low-cost, and permanent method of carbon removal into a reality.
What you'll do - Develop and validate hydrodynamic, sediment transport, and water quality models for near-shore coastal enhanced weathering deployment sites
- Develop statistical/empirical and mechanistic models to simulate the dissolution of alkaline minerals and release of alkalinity
- Use data from field trials to improve models, including data assimilation techniques
- Work alongside marine biogeochemists to develop deployment and monitoring strategies that ensure alkalinity dissolution, the avoidance of secondary precipitation, and ecological safety
- Evaluate prospective project sites and develop deployment and monitoring plans for those sites
- Participate in industry consortia to develop best practices and standards for applying ocean models to mCDR and MRV
- Engage with communities, interest groups, and government officials to educate and garner support for Ocean Alkalinity Enhancement as a CDR method
You should have - PhD in Oceanography, Marine Science, Biogeochemistry, or a related field
- Deep understanding of coastal dynamics and sediment transport processes
- 3+ years developing and validating hydrodynamic and sediment transport numerical models using platforms such as Delft3D, HydroBioSed, and FlexSem
- A solid understanding of biogeochemical models and ocean chemistry
- An understanding of machine learning or data assimilation to optimize models
- Experience with regional or global oceans such as ROMS, MITgcm, and Oceananigans is a plus
- Experience with reactive transport models is a plus
- You know how to develop and run models in a computationally-efficient manner
- A passion for taking OAE from concept to reality and restoring our climate and ocean
What we offer - Generous equity as an early employee
- Health, dental, and vision benefits
- 401(k) plan
- 10 holidays annually + flexible PTO
- The adventure of taking OAE from concept to reality
This is an on-site position (not hybrid) in our Santa Clara, CA headquarters. Must be authorized to work in the US. We will sponsor visas, but must have existing authorization. The expected salary for this position is $100,000 - $150,000 USD depending on experience.
