Tech­ni­sche Uni­ver­si­tät Dres­den - Fac­ulty of Envir­on­mental Sci­ence, Depart­ment of Geosciences, Insti­tute of Plan­et­ary Geodesy, Lohr­mann Obser­vat­ory

Tech­ni­sche Uni­ver­si­tät Dres­den (TUD), as a Uni­ver­sity of Excel­lence, is one of the lea­ding and most dyna­mic rese­arch insti­tu­ti­ons in the coun­try. Foun­ded in 1828, today it is a glo­bally ori­en­ted, regio­nally ancho­red top uni­ver­sity as it focu­ses on the grand chal­len­ges of the 21st cen­tury. lt deve­lops inno­va­tive solu­ti­ons for the world's most pres­sing issues. In rese­arch and aca­de­mic pro­grams, the uni­ver­sity unites the natu­ral and engi­nee­ring sci­en­ces with the huma­nities, social sci­en­ces and medi­cine. This wide range of disci­pli­nes is a spe­cial fea­ture, faci­li­ta­ting inter­di­sci­pli­na­rity and trans­fer of sci­ence to society. As a modern employer, it offers attrac­tive working con­di­ti­ons to all employees in tea­ching, rese­arch, tech­no­logy and admi­nis­tra­tion. The goal is to pro­mote and deve­lop their indi­vi­dual abi­li­ties while empowering ever­yone to reach their full poten­tial. TUD embo­dies a uni­ver­sity cul­ture that is cha­rac­te­ri­zed by cos­mo­po­li­ta­nism, mutual appre­cia­tion, thri­ving inno­va­tion and active par­ti­ci­pa­tion.

For TUD diver­sity is an essen­tial fea­ture and a qua­lity cri­ter­ion of an excel­lent uni­ver­sity. Accord­in­gly, we wel­come all app­li­cants who would like to com­mit them­sel­ves, their achie­ve­ments and pro­duc­tivity to the suc­cess of the whole insti­tu­tion.

Research Asso­ci­ate (m/f/x)

At the Fac­ulty of Envir­on­mental Sci­ence, Depart­ment of Geosciences, Insti­tute of Plan­et­ary Geodesy, the Lohr­mann Obser­vat­ory (, offers, in rela­tion to the ESA mis­sion Gaia, a pro­ject pos­i­tion as

Research Asso­ci­ate (m/f/x)
(sub­ject to per­sonal qual­i­fic­a­tion employ­ees are remu­ner­ated accord­ing to salary group E 13 TV-L)

start­ing at the earli­est pos­sible date. The pos­i­tion is cur­rently avail­able for a dur­a­tion of 1 year. Sub­ject to the avail­ab­il­ity of funds, exten­sions may be pos­sible up to the end of the pro­ject in about 2030. The period of employ­ment is gov­erned by Fixed Term Research Con­tracts Act (Wis­senschaft­szeitvetra­gs­ge­setz-Wis­sZeitVG). Bal­an­cing fam­ily and career is an import­ant issue. The post is gen­er­ally suit­able for can­did­ates seek­ing part-time employ­ment. Please indic­ate your request in your applic­a­tion. You also have a pos­sib­il­ity to work remotely.

Working field:

The goal of the space tele­scope Gaia ( is the determ­in­a­tion of the spa­tial pos­i­tions and velo­cit­ies as well as the astro­phys­ical char­ac­ter­ist­ics of about 2 bil­lion celes­tial objects. Gaia is con­sidered as a revolu­tion in astro­nomy and enjoys the highest inter­na­tional repu­ta­tion.
The team of the Lohr­mann Obser­vat­ory is part of the European Gaia Con­sor­tium and primar­ily respons­ible for the relativ­istic aspects of the data pro­cessing as well as the defin­i­tion, com­pu­ta­tion and ana­lysis of the astro­met­ric solu­tions of Gaia.

Research work in the area of space astro­metry with Gaia, espe­cially:
  • ana­lysis of the data and sci­entific res­ults of Gaia;
  • design, imple­ment­a­tion and applic­a­tion of algorithms and soft­ware for the Gaia data pro­cessing as well as for the data ana­lysis and report­ing.
The focus of the activ­ity will be adjus­ted accord­ing to per­sonal qual­i­fic­a­tions and can include for example the applic­a­tion of the machine learn­ing tech­niques for the ana­lysis of resid­uals and/or the devel­op­ment of the soft­ware auto­mat­ing the selec­tion and veri­fic­a­tion of quas­ars in the Gaia data.


  • uni­versity degree in astro­nomy, phys­ics, math­em­at­ics, com­puter sci­ence or related areas;
  • reas­on­able exper­i­ence in soft­ware devel­op­ment; fur­ther IT-back­ground is a plus;
  • capa­city for inde­pend­ent, goal-ori­ented work, high motiv­a­tion, read­i­ness to integ­rate and to take on respons­ib­il­it­ies in the team.
  • Reas­on­able know­ledge in applied math­em­at­ics (for example, stat­ist­ical data ana­lysis), phys­ics and astro­nomy is highly desir­able.

How to apply:

TUD strives to employ more women in aca­demia and research. We there­fore expressly encour­age women to apply. The Uni­versity is a cer­ti­fied fam­ily-friendly uni­versity and offers a Dual Career Ser­vice. We wel­come applic­a­tions from can­did­ates with dis­ab­il­it­ies.
