At ASML, our teams create and implement software designs that run in the most modern semiconductor fabs in the world, helping our customers like Samsung, Intel and TSMC make computer chips faster, smaller, and more efficient. Here, we’re always pushing the boundaries of what’s possible.

In the Applications Algorithms group we are responsible for the development and implementation of the common algorithms that are then used by other teams to develop applications to optimize the production process of our customers. We are a group of experts on mathematics, algorithms, numerical methods and software engineering.

We are looking for a new colleague with solid mathematical and industrial (Java based) software engineering experience and has specially expertise in optimizing algorithms for run-time performance and experience with developing for the Apache spark engine.
