ELI (Extreme Light Infrastructure) is a multi-site European Research Infrastructure Consortium devoted to the scientific research using new generation lasers. ELI-Beamlines is one of the the sites and is currently being constructed in Dolní Břežany (just south of Prague, Czech Republic). The commissioning of the facility is just starting. ELI-Beamlines will deliver ultra-short (few tens of femtoseconds), ultra-intense laser pulses in an unprecedent combination of high intensity and repetition rate. It will make available a unique combination of synchronized beams from the primary lasers and secondary ionizing radiation sources for a wide range of interdisciplinary applications in physics, chemistry, medicine, biology and material science.

For our Monte Carlo simulation group, we are seeking a suitable candidate for a junior or senior position (depending on qualifications) as:
