Expert computational scientist

Are you an expert in the field of computational science with a strong background in numerical analysis? Do people come to you for advice about numerical computing and analysis or even to talk strategy on this? Do you dare to share your vision to advise Deltares on how to transform our hydrodynamic and morphodynamic simulation products?  Then, respond to this vacancy! We are looking for an innovative computational scientist to help shape our software! 

What you can expect as expert computational scientist 

Our Hydrodynamics and morphology (HDM) software productline is one of the flagships of Deltares. Our software product is open source and is of very high standard. That is necessary because the problems they solve help us in enabling Delta life around the globe. All this means that we must keep pioneering in this field to uphold our mission. And that is where you come in! We are looking for an expert to help shape our software.

As an expert computational scientist you will explore and study numerical schemes, help people translate these concepts into source code and be a bridge between our business departments and software department. From this role you inspire people and guide them in the right direction through leading by example. You advice many stakeholders and you will have ownership of the vision and initiatives, allowing you to shape the direction and outcomes. 

What makes it challenging and fun? 

  • Creating impact together: by establishing solid numerical schemes, you contribute to the development of high-quality software that helps address societal issues worldwide. 
  • Interdisciplinary teams: You will be part of a product development team, consisting of 35 professionals. You will work within a field that contains many stakeholders and with a large and growing R&D team of professionals. With range of expertise between (for example) numerics, High Performance Computing, GPU computing, and Software Product Development. These colleagues will help translate the R&D into product development.
  • Legacy: You will engage in a long-term plan with skilled colleagues as to keep our legacy code relevant for the upcoming period of time. You will be part of a significant flagship product team. 

Who are we looking for?

We are looking for a passionate expert who is committed to contribute in our long-term strategy to successfully transform our numerical software. With an innovative, open mindset who is receptive to new ideas and can connect professionals and inspire them. Furthermore, you bring: 

  • Solid experience (15+ years) in computational science and profound knowledge of numerical analysis. An academic degree (preferably with PhD ) in computer science, computer engineering, applied mathematics, aerospace engineering or similar with a keen interest in computational fluid dynamics.
  • An interest in the analysis and implementation of spatial and temporal discretization of linear and non-linear Partial Differential Equations with application towards our hydrodynamic and morphodynamic simulation products.
  • Experience in leading other researchers in the conceptualization, analysis and prototyping of numerical software and turning this into a sustainable product.
  • Excellent communication skills to effectively collaborate with various stakeholders and colleagues. 
  • You are familiar with terms like: implicit time integration, unstructured meshes, linear and nonlinear solvers, preconditioners, turbulence models, stability analysis, etc.

What we offer: 

  • Deltares offers a contract for 12 months with the intention of a contract for an indefinite period of time. Salary will be based on your experience with a maximum of € 8.191 gross per month based on 40 hours per week. This role can be filled in parttime or fulltime.
  • Hybrid working is among the possibilities. We properly provide facilities for you to work from home.
  • 34 vacation days based on 40 hours per week, ABP pension, vitality budget, mobility budget and a compensation for healthcare expenses.
  • Excellent training opportunities for personal and professional growth.
  • Here you can find more information about our attractive terms of employment.
