Who are Net-Zero Geosystems?
Net-Zero Geosystems (NZG) is a science and technology Team focused on the development of geoscientific simulation tools and services for the subsurface. The focus of our work is to provide robust evidence-based tools to lower the operational risks of subsurface projects. We are driven to deliver industry-leading & high-performance software for our clients. NZG is working on the geosystems of the energy transition (CO2 storage, geothermal energy, radioactive waste disposal and hydrogen storage) and on traditional geosystems (such as oil & gas). NZG’s ambition is to drastically improve the value that simulations tools deliver and to become a major software provider of the subsurface industry. Beyond the success of NZG, we are interested in benefitting society while limiting harm to humans and the environment. We are a small and growing Team, we value in-person interactions, collaboration, accountability, clarity of communications and compassion.
Our technology
Our principal technology predicts the probability of subsurface well integrity loss and leakages. Ensuring a sustained long-term containment of greenhouse gases and harmful fluids is crucial for all energy geosystems. Reliable well integrity prediction methods are key for gaining confidence in subsurface projects, obtaining regulatory & financial approval, and facilitating the implementation of economically viable measures for risk prevention and mitigation. Specifically, our technology will dramatically improve the longevity of wells and their resilience, reduce risk, reduce environmental impact, drive costs down, enable well re-purposing and ensure permanent containment (of CO2, radioactive materials, methane …).
The role
The Computational Geoscientist will be driving the delivery of NZG’s R&D and applied projects. They will develop innovative software, undertake scientific research and apply our technology for our client’s operations. R&D projects will be focussed on developing our simulators and the QRA (Quantitative Risk Assessment) frameworks built around them. The QRA frameworks leverage statistical methods (Monte-Carlo, sensitivity analysis) and optimization methods to provide users with failure probabilities (e.g. leakages, fault reactivation & seismicity) and means to reduce them. Applied projects include supporting well integrity experiments and leveraging our technology to solve complex subsurface problems.
Responsibilities
· Software development: Develop innovative software and physics models, write theory documents, conduct validation and calibration tests, write unit tests, manage the codebase (git/GitHub), conceptualise user interfaces and liaise with subcontractors for the deployment of our software on the cloud.
· Project delivery: Lead the delivery of work packages and technical objectives for our R&D and applied projects, write deliverable descriptions, monitor progress and ensure deadlines are met, communicate with other team members involved.
· Product development: contribute to product direction, understand user and design product specifications to meet them effectively, align business and technical objectives.
· Building the Team: help shape our Team culture, participate in hiring and onboarding, establish workflows and communication norms that keeps the Team organised and efficient.
· Communication and collaboration: Regularly present research outcomes, project milestones, and development progress to the Team, external stakeholders, and to the industrial and scientific community.
· Customer and community engagement: Talk to our users and support them, gather user feedback, write LinkedIn posts and case studies, speak at events.
About you
The ideal candidate is an excellent team player with experience in developing numerical methods and physics solver (FEM, FDM, FVM…), Python and C++ skills, strong mathematics skills, knowledge of solid & fluid mechanics theory, and a background in Geosciences. In particular, we are looking for:
· Self-reflection and emotional intelligence
· Scientific rigour and attention to detail.
· Awareness beyond technical considerations such as business and client priorities.
· A track record of delivering and meeting deadlines.
· Excellent written and verbal communication skills .
· Proficiency in Python, C++, Paraview, Linux, LaTeX, Git.
· Experience in deriving partial differential equations, developing implicit solvers (for thermo-hydro-mechanical and chemical coupled physics).
· Experience in developing finite element, finite volume and finite difference software.
· A background in geoscience, in particular petroleum engineering.
The list above is an ideal, we encourage you to apply even if your experience doesn’t cover every item – you can learn with us. We value curiosity, a willingness to learn, and a genuine interest in the role.
What does Net-Zero Geosystems offer?
· Flexible working hours
· Hybrid working (at present, 3 days in the office and 2 days remote)
· 25 days holiday (excluding bank holidays)
Our office is in London, so the role is only suitable for UK-based individuals living within a commutable distance from London (<1h) and to those willing to relocate.
