Fraun­ho­fer IIS - We have an imme­di­ate Open­ing in our »Audio and Media Tech­no­lo­go­gies« Divi­sion of Fraunhofer IIS in Erlan­gen, Ger­many, for a

Audio Signal Pro­ces­sing Rese­ar­cher*

Are you fasci­na­ted by audio signal pro­ces­sing and C pro­gramming? Are you keen on deve­lo­ping cut­ting-edge tech­no­logy for smart assi­stant devices?

Work­ing field:

If so, we have the right posi­tion for you!
Your pri­mary task con­sists of deve­lo­ping new audio signal pro­ces­sing algo­rithms, mainly in the field of micro­phone pro­ces­sing and speech enhan­ce­ment. This deve­lop­ment typi­cally invol­ves mul­ti­ple steps: The first step is to gather a good over­view of state-of-the-art approa­ches that could be sui­ta­ble to solve the given pro­blem. In a second step, the approa­ches need to be adap­ted to solve our spe­ci­fic pro­blem, e.g., they need to be adap­ted to our spe­ci­fic hard­ware devices or requi­re­ments. In many situa­ti­ons, it is necessary to deve­lop our own algo­rith­mic solu­tion from scratch, if no solu­tion exists in the lite­ra­ture. Once a basic algo­rithm is draf­ted, e.g., in MAT­LAB or Python, the algo­rithm needs to be tested and its prac­ti­cal app­li­ca­bi­lity needs to be veri­fied. This requi­res to carry out acoustic mea­su­rements in the labo­ra­tory and/or to con­duct acoustic simu­la­ti­ons. The eva­lua­tion is per­for­med based on objec­tive mea­su­res, but it also can involve lis­ten­ing tests. Once the prac­ti­cal app­li­ca­bi­lity is veri­fied, the basic algo­rithm needs to be trans­for­med into a fea­ture-com­plete and pro­duct-ready algo­rithm, which inclu­des robusti­fi­ca­tion and fine-tuning, e.g., for spe­ci­fic con­su­mer devices.

Your second main task con­sists of por­ting the newly deve­lo­ped MAT­LAB or Python algo­rithm into a pro­duct-ready and com­pu­ta­tio­nal effi­ci­ent C library. If the algo­rithm was deve­lo­ped by other col­leagues, you should under­stand and verify the algo­rithm such that algo­rith­mic pro­blems can be spot­ted and remo­ved while por­ting the algo­rithm to C. Once the por­ting is finis­hed, the imple­men­ta­tion needs to be veri­fied in terms of accu­racy and com­ple­xity.

What you can expect from us
The Fraun­ho­fer IIS offers a diverse and chal­len­ging field of work in an inter­na­tio­nal envi­ron­ment, ori­en­ted toward state-of-the-art rese­arch and tech­no­logy, with the oppor­tu­nity for per­so­nal and pro­fes­sio­nal deve­lop­ment.
Fur­ther­more, we offer work-life balance through fle­xi­ble working hours and various sup­port pro­grams.

Appoint­ment, remu­ne­ra­tion and social secu­rity bene­fits based on the public-sec­tor collec­tive wage agree­ment (TVöD).
In case of iden­ti­cal qua­li­fi­ca­ti­ons pre­fe­rence will be given to severely dis­ab­led can­di­da­tes.
We would like to point out that the cho­sen job title also inclu­des the third gen­der.
The Fraun­ho­fer-Gesell­schaft empha­si­ses gen­der-inde­pen­dent pro­fes­sio­nal equa­lity.

Fraun­ho­fer is Europe’s lar­gest app­li­ca­tion-ori­en­ted rese­arch orga­ni­za­tion. Our rese­arch efforts are gea­red ent­i­rely to people’s needs: health, secu­rity, com­mu­ni­ca­tion, energy and the envi­ron­ment. As a result, the work under­ta­ken by our rese­ar­chers and deve­lo­pers has a signi­fi­cant impact on people’s lives. We are crea­tive. We shape tech­no­logy. We design pro­ducts. We improve methods and tech­ni­ques. We open up new vis­tas.
