Full-time developer position opening for 2017

This is an announcement for a full-time developer (Ingénieur de Recherche) position opening at Université Grenoble-Alpes, working on open source software engineering for computational mathematics.

contact: clement.pernet@imag.fr and jean-guillaume.dumas@imag.fr


For 2 years (one year renewable) starting early 2017. Interviews will be run in December 16 and January 17.


Approx. 2200 € of monthly salaire net (salary after non-wage labour cost but before income tax).


The developer will work at the LJK lab. on the campus of Saint-Martin d’Heres, 15 minutes from Grenoble city center by public transportation.


Exact linear algebra, computing with arbitrary precision integer or rationals, and over finite field, is a core component of computer algebra software and also plays a central role in numerous computation intensive applications, ranging from algebraic cryptanalysis to experimental mathematics. The LinBox library and its components, the Givaro and the FFLAS-FFPACK libraries, form a C++ library ecosystem offering high performance implementation of the most common exact linear algebra routines. These open-source libraries are integrated in the SageMath open-source mathematics software.

Recently the FFLAS-FFPACK library has been parallized for multi-core architectures which opens way to two development directions:


The mission of the engineer will be to

Skills and background required

The following are not prerequisites but would be very much appreciated:


Applicants should send an email to clement.pernet@imag.fr and jean-guillaume.dumas@imag.fr with:

Both documents must be in an open format (pdf, ps, plain text, …) either in french or english.


The position will be funded by

OpenDreamKit, a Horizon 2020 European Research Infrastructure project that will run for four years, starting from September

  1. This project brings together the open-source computational mathematics ecosystem – and in particular LinBox, MPIR, SageMath, GAP, PARI/GP, LMFDB, Singular, MathHub, and the IPython/Jupyter interactive computing environment. – toward building a flexible toolkit for Virtual Research Environments for mathematics. Led by Université Paris-Sud, this project involves about 50 people spread over 15 sites in Europe, with a total budget of about 7.6 million euros.

The developer will work within a team of developpers of SageMath and LinBox, and researchers in the field of high performance computer algebra at the Laboratoire Jean Kuntzmann.
