Successful together

Working for AS

“Committed staff who also think outside the box” is how company founder Andreas Szeteli describes his workforce. A profile that we also want to see in job applicants.

For over 30 years, the team of employees has been able to advise and actively and successfully support many clients, including international ones, and help them with well-thought-out designs and technical solutions. In the service sector too, it was only by offering impeccable quality that AS was able to establish itself in the market.

Andreas Szeteli is convinced that a flat corporate hierarchy can only be successful if everyone is willing to take responsibility: “We work meticulously, always have a different take on things and look for client-oriented results”.

AS requires a high level of personal initiative and expertise from any new employee, within a very short time of them joining the company. The team consists of ambitious individuals who are fully committed at all times and make decisions independently. If you recognise yourself in this and want to help AS move forward, then please apply.
