Coding with Impact:
Use your code to control factories around the world.
At tetys, you’re guaranteed never to be programming or designing for a vacuum of a consumer market or short-lived, trendy apps. Your complex source code is still moving tonnes of material today and tomorrow in the factory halls of our industrial clients worldwide. Create Impact with us.
_smooth operation.
Flat hierarchies are usually just a hollow, completely meaningless buzzword in start-up job adverts. But for us, it reflects the reality of our developers’ working lives. And it doesn’t matter at all whether you’re an experienced Java backend architect, an agile frontend hero redesigning the control centre dashboard, a meticulous database expert handling terabytes of cyclical raw data, or a pragmatic senior consultant tackling the day-to-day challenges on the shop floor – you’ll always have the autonomy, the trust and, above all, the freedom to make a significant and lasting impact on massive, multi-million projects directly at the client’s site.
Sounds too good to be true? We sort of think so too… But to convince you, that’s why our recruitment process includes an interview with your future colleagues – and not ‘just’ with our (admittedly very friendly!) HR team.

_Can you feel the tech vibes in Aachen?
The imperial city of Aachen is renowned as a vibrant, world-class European technology hub. Here, we offer you a strong entrepreneurial foundation and a supportive social environment, enabling you to flourish both professionally and personally without a care in the world.
Enjoy flexibility. And a fantastic place to work.
Our modern matrix models for fully hybrid working and personalised working-life models adapt smoothly and logically to your personal, family (or, perhaps at the moment, student) circumstances and stage of life. Whether you’re working remotely or in the office in one of Aachen’s most modern office buildings on the RWTH Aachen Campus: enjoy your flexibility.
In-depth experiential knowledge and innovative AI, line by line
Work side by side with our veteran developers day in, day out on the very core algorithms of the manufacturing industry, and help them harness the power of AI to further develop tetys companion MES and APS. In doing so, immerse yourself in the wealth of knowledge provided by experts who, in some cases, have over 30 years’ experience in system modelling.
The two ‘t’s in ‘tetys’ stand for ‘team of people’
From legendary team lunches and impromptu after-work barbecues to the big summer party – tetys is deliberately not a sterile corporate department of a financial holding company, but at its core a deeply rooted family of tech-savvy craftspeople.
