deZem GmbH

Energy effi­ciency is our mis­sion. To reduce global energy con­sump­tion and global warm­ing, the cre­ation of trans­par­ency is the key. With our team of 20+ inspired col­leagues we develop and mar­ket innov­at­ive sys­tems for Energy Con­trolling (ana­lysis soft­ware, data log­gers, sensors etc.). These tools help our cus­tom­ers in cre­at­ing trans­par­ency, in effi­ciently man­aging their energy con­sump­tion and in sus­tain­ably redu­cing their run­ning costs for energy and main­ten­ance. Our cus­tom­ers come from many dif­fer­ent busi­ness areas all over the world. They include global play-ers with mul­tina­tional man­u­fac­tur­ing sites, pub­lic prop­erty admin­is­tra­tions, uni­versit­ies, data centres and large, eco­logy-minded mines, as well as schools and research groups. We also use our soft­ware for mon­it­or­ing and con­trolling the per­form­ance of all our IT sys­tem com­pon­ents. Be-sides, we pro­duce over 100 kg of honey every year with our 'office bee­hive' which, of course, is extens­ively metered.

PHP developer (m,f,d)

Save the World with your PHP skills

Work­ing field:

Did you ever want to change The World for the bet­ter but did not know where to start? Then join us and save the World with your PHP skills! We develop the tools to allow our cus­tom­ers to under­stand their energy flows and almost always reveal ways for them to reduce the amount of required resources drastic­ally. That does not just save the resources for future gen­er­a­tions but also our cus­tom­ers' money. For our devel­op­ment team that means to deal with huge amounts of data that need to be visu­al­ized in real time to provide the neces­sary insights without fric­tions.

Your Tasks:
As a backend developer you will work on the scalab­il­ity of our aggreg­a­tion frame­work, the nec-essary con­fig­ur­a­tions and the API to our fron­tend. We believe in the power of the web: All our tools for ana­lys­ing and visu­al­ising the data run in the browser. You will work in close and con­tin-uous exchange with the fron­tend developers, product own­ers and test­ers so as to ensure a flu­ent pro­cess. There are no arti­fi­cial bound­ar­ies between depart­ments and you are very wel­come to bring in your opin­ion and ideas.
