About AS

Welcome to as

Who we are

Safety first - the protection of people and the environment, but also the protection of valuable chemicals have always been the focus of AS’s thoughts and actions. From its beginnings in 1987 as a manufacturer of high-tech pumps for drum emptying, AS has developed into a leading global specialist for safe dispensing and filling systems, with business partners in high-tech industries such as the semiconductor, pharmaceutical, chemical and solar industries. Many well-known large companies, such as BASF, Bosch, Merck, Brenntag or Infineon, but also numerous medium-sized companies trust today in the innovative products and services of the German inventors from Ostfildern near Stuttgart. In America and Asia, foreign subsidiaries ensure proximity to customers and an export share of over 60 percent.

A dedicated team of around 100 employees is constantly developing the portfolio at the family-owned company, which now includes smart IoT solutions for sustainable chemical handling as well as robotic systems for fully automated filling and emptying of containers. For chemical plant engineering, AS offers various fittings, valves and hoses made of high-performance plastics - often also as custom-made products, which are realized with in-house injection molding and CNC machines. At AS, you can expect innovations, both large and small, for liquid chemicals and for all types of containers - from bottles to drums and IBCs to tank trucks. With built-in safety.

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.
