Job Description (Summary):

Hourglass is seeking an experienced Numerical Modeler (fixed-term, 12 months – full-time or part-time) to support the sediment transport programs within the organisation. These programs are focused on building our knowledge around sediment transport processes relevant to OAE projects, contributing to the design of OAE pilot projects and developing sediment transport-related components of our extensive monitoring programs.

Job Description:
Much of Hourglass Climate’s research is focused on mineral-based OAE strategies that use alkaline rocks and minerals dissolved in seawater to remove atmospheric carbon dioxide. Tracking the transport fate of these minerals when deployed is an essential component of robust carbon removal quantification, as well as environmental impact quantification. Hourglass is seeking an experienced Numerical Modeler (Coastal / Marine) (fixed-term, 12 months) to support the sediment transport programs within the organisation. These programs are focused on building our knowledge around sediment transport processes relevant to OAE projects, contributing to the design of OAE pilot projects and developing sediment transport-related components of our extensive monitoring programs. 

The role is desk-based, with a focus on numerical modeling and the analysis of field data. The successful candidate will lead the development and application of numerical models (e.g. Delft3D, OceanTracker) to understand sediment transport processes and pathways in coastal / marine environments, informed and validated by field observations where available. Experience with lagrangian particle tracking models is particularly desirable. Model outputs and data analyses will be used to support OAE field trial design, including advising on and deploying appropriate instrumentation for sediment tracking, as well as interpretation of field trial outcomes. 

The ideal candidate will be able to work independently in a fast-paced environment, and will take clear ownership of the projects they are responsible for. While able to work independently, we are looking for a collaborative team member with a “no-task-too-small” mindset who actively supports colleagues and contributes to our positive, high-performing team. Hourglass’ projects are highly interdisciplinary and successful collaboration with specialists across disciplines is critical. 

This is a remote position. However, to maintain a high level of collaboration, the successful candidate must be available to work, at a minimum, during a 5-hour window aligned with US Eastern Time, three days a week. Outside of these required collaboration blocks, this position offers the flexibility to design a schedule that works best for your local time zone. 

The ideal candidate will easily fulfill the responsibilities of this position (as described below) and have the following qualities and experience: 

Responsibilities: 

● Lead numerical modeling (e.g. Delft3D, OceanTracker) workflows, including model development, calibration, scenario development, data extraction and technical interpretation of results 

● Apply lagrangian particle tracking models to determine and predict sediment transport pathways at OAE pilot sites 

● Work closely with other disciplines within the organisation in the delivery of modeling results 

● Advance the design and implementation of the sediment transport aspects of our OAE monitoring programs 

● Provide technical input into Hourglass’ projects, with regards to sediment transport processes and hydrodynamics 

● Support oceanographic data acquisition activities, including advising on data needs and appropriate instrumentation, with the potential to support data collection in the field ● Contribute to modeling in support of research permit applications 

● Communicate scientific findings through technical documentation and conference presentations 

● Contribute to publications consisting of rigorous and high-quality datasets in collaboration with the science team. 

● Contribute & Collaborate: bring a depth of knowledge and ideas to projects across Hourglass’s sediment transport programs. The ideal candidate will be curious and motivated to share their knowledge and apply it in new ways.  

Compensation: 

Salary is based on the candidate's experience and ranges from $70 - $94k USD for US-based candidates. Please note that the final compensation for international hires is calculated based on local benchmarks. This ensures internal equity across our global team while remaining competitive within your local economy.
