Josef Auer

CTO to Hire

Born in Lower Austria, as a son of cook and restaurant owner, great food was always important to him. He enjoys eating cuisine from different cultures and kitchens and likes to cook himself. As long as meat is involved, he will probably try it.
He loves volleyball, which he started playing at the age of 12. Back then he joined a local team and played competitively in regional and national championships. After a series of injuries he had to stop playing regularly but still has a soft spot for the sport.
Travelling is his passion and he aims to experience as much of this planet as possible. Among the places he already has visited is Iceland, which he feels is the most beautiful country on this planet. He hopes after COVID there will be a push for more sustainable travel, including more remote work.
He recently got a Husky puppy and enjoys the soothing effect he has on him a bit more than the patience he teaches him.
In his professional life he focus on bringing Product and Tech closer together. Looking holistically at the end-to-end Product lifecycle he removes barriers between teams and departments. His experience has shown him well structured teams will deliver in their highest capacity. He enjoys researching technologies and applying them in the best fit for the problem given.
