Helm­holtz-Zen­trum Dres­den-Ros­sen­dorf e.V.

Through cut­ting-edge research in the fields of ENERGY, HEALTH and MAT­TER, Helm­holtz-Zen­trum Dresden-Rossen­dorf (HZDR) solves some of the press­ing soci­etal and indus­trial chal­lenges of our time. Join our 1.500 employ­ees from more than 50 nations at one of our six research sites and help us mov­ing research to the next level!

The Cen­ter for Advanced Sys­tems Under­stand­ing (CASUS) is a Ger­man-Pol­ish research cen­ter for data-intens­ive digital sys­tems research. CASUS was foun­ded in 2019 in Görl­itz and con­ducts digital inter­dis­cip­lin­ary sys­tems research in vari­ous fields such as earth sys­tems research, sys­tems bio­logy and mater­i­als research.

The CASUS invites applic­a­tions as

CASUS Pro­fes­sional Sup­port, C++ Soft­ware Par­al­lel­iz­a­tion Expert (f/m/d)

The pos­i­tion is avail­able imme­di­ately.

Working field:

Applic­ants (f/m/d) will work on the devel­op­ment and main­ten­ance of exist­ing soft­ware pack­ages for port­able par­al­lel het­ero­gen­eous com­put­ing, par­al­lel­iz­a­tion of exist­ing research soft­ware pack­ages, and co-devel­op­ment and main­ten­ance of par­al­lel sci­entific research soft­ware codes. You will be part of the CASUS Pro­fes­sional Sup­port Team and will be work­ing closely with the HZDR Depart­ment of Inform­a­tion Ser­vices and Com­put­ing and the HZDR Insti­tute of Radi­ation Phys­ics.
