Senior Backend Software Engineer

We are looking for a talented software developer to join our top-of-the-world class team of material scientists in Espoo. Our team develops new materials for industry that are more durable, consume less critical raw materials and replace non-renewable materials with bio-based alternatives. In this full-time permanent position, you have an opportunity to develop future solutions together with VTT material scientists for better tomorrow.

Our team 

VTT ProperTune is a brand name for research and customer solutions activities in area of new material development using multiscale materials modelling. Development of new materials requires deep understanding of material and production process behavior. Physical and chemical phenomena are affected from the nano- and/or molecular level up to macroscopic level. For this purpose, integrated computational materials engineering (ICME) skills have developed rapidly in recent decades, with the support of increased numerical calculation capacity and commercial, open source and in-house multi-level and multi-physics software development. You will be working in ProperTune ICME Integration -team side-by-side to material scientists developing in-house software used for numerical materials modelling.

Your role

Materials modelling is based on use of many commercial and open source software, but even more importantly on our in-house software development. Computation of models is conducted in own cluster and using CSC services. Your main responsibility is to develop our in-house software components and used software architecture in order to optimize the code, decrease computational requirements and to create fluent workflow management for software components. You develop used frameworks and architecture e.g. toward service oriented architecture for material models and virtual experiments. You will also consider good data management policies, parametrization of code and utilization of machine learning and AI solutions. We expect management of full development cycle: Design, develop, deploy, operate and improve important software solutions that affect customers inside and outside of VTT.

We are currently using following languages and technologies: Python, C/C++, Fortran, Julia, hdf5, Linux, GIT and CSC-services. But more important than technologies is that you can solve problems with appropriate tools and technologies in long-lasting way.

Your background & competences

We expect that you have excellent development skills in Python and in C++.  Skills in Fortran, Julia and hdf5 are considered beneficial, as well as experience in scientific computation and High Performance Computing environments and respective development tasks.

You know well different available technologies and are able to select best technologies for each project. You are familiar with agile development principles and can create and maintain clear technical documentation in English. Collaboration with experts from different disciplines is essential in the projects.

A successful applicant is expected to have an MSc degree or equivalent in computer science or in relevant field and ideally at least 5-10 years industrial experience. However, we are also interested in someone with less experience but with enthusiasm for self-development. Interest in material science, physics and/or chemistry is considered beneficial as well as the interest in conducting research.

What we offer

VTT provides an inspiring working environment that pools together world-class research, innovations and top experts. Our mission is to create impact that generates sustainable growth and wellbeing in society as well as in industry.

Our people are the core of the next generation VTT. Therefore, our personnel’s wellbeing, flexible work opportunities and competence development are key priorities for us. With us, you can make an impact for a better future and you can be part of solving the biggest challenges of our time.
