HPC Expert / Scientific software developer C, openMP, MPI

Are you looking for a role where you can use your expert HPC coding knowledge to help scale advanced wave-based imaging software to large HPC environments so that we can 'see' better into the subsurface and possibly into infrastructure as well? And are you excited about working in a small group of highly skilled and motivated scientific software engineers in a startup environment? Then come and join us at Quantairra R&D Services, a startup company that is part of one of Europe's leading incubators (YES!Delft) on the campus of Delft University of Technology (TU Delft) and develops advanced wave-based imaging software.

You will work as an HPC expert and scientific software developer in a small team within an innovative and vibrant technology-oriented startup community here at YES!Delft, the incubator of TU Delft.
Your primary responsibility will be to help scale our advanced wave-based subsurface imaging and signal processing algorithms for use in large HPC environments using the C programming language (and possibly C++), openMP and MPI.
Your initial focus will be on software development for application in seismic subsurface imaging/inversion for which we have a project with a launching customer.
At a later stage, we will consider using other types of data aimed at improving imaging/inversion in settings with a focus on civil engineering for climate adaptation or structural health monitoring.
Besides offering an attractive salary and bonus package, we offer intellectually and scientifically challenging and stimulating work.
And because we are a startup, we offer exceptional candidates the ability to earn part financial ownership in the company through our attractive employee participation scheme.

Key responsibilities

Software development in C (and possibly C++) to help scale our advanced wave-based imaging algorithms for use in large HPC environments using openMP and MPI

Actively participate in R&D on advanced wave-based imaging/inversion

Team culture

Our team culture is based around a shared drive and joy to create and build high-value wave-based imaging and inversion software while leveraging high-performance computing.
We inspire each other to get the most out of ourselves to build the best possible products for our clients.
In the face of tough problems, we are resilient, communicate with each other honestly and openly and help one another to come up with creative solutions.
We don't give up until we reach our goal and feel responsible for the contribution the team needs from us.
And, importantly, we do not forget to celebrate together when we reach our goals.
We do this because we share the belief that together we can reach far beyond what any of us can do individually.
