Om Avaron AB
Avaron grundades med visionen om att skapa ett konsultbolag där kompetens och livskvalitet går hand i hand. Vi är ett nischat team som idag verkar inom komplexa miljöer såsom bank, finans och storskalig industri.
Som konsult hos oss får du det bästa av två världar: tryggheten och de spännande uppdragen hos stora, etablerade uppdragsgivare, kombinerat med det lilla bolagets snabbhet, transparens och personliga kontakt.
Vi tror inte på krångliga hierarkier eller onödig administration. Istället lägger vi kraften på det som faktiskt betyder något – att leverera värde i våra projekt och att se till att våra medarbetare trivs, utvecklas och har en balans i livet som fungerar på riktigt.
