We are a colorful team of over 300 congstars and belong to one of the best employers and leading telecommunications providers in Germany. You can find us right in the heart of Cologne in the beautiful Rheinauhafen or remotely working from home.

As part of Deutsche Telekom, we offer the best of both worlds: We combine the flexibility of a start-up with the security of a corporation behind us.

Diversity inspires us — our own and yours. With us, it is allowed and even desired to question things. We really enjoy what we do and it shows. We're colorful, we're creative and we're in the mood — for you!

Among other things, we offer:

Flat hierarchies and the opportunity to actively shape our processes, products and congstar as a company
Flexible working hours and hybrid working model at Cologne's Rheinauhafen (up to 70% remote work is currently possible)
Work (up to 20 days/year in other EU countries)
Free access to a mental health platform including individual and group sessions as well as webinars with psychological experts and coaches for your mental wellbeing as well as other comprehensive health services
Attractive discounts for employees
Deutschlandticket subsidy and bicycle leasing to promote sustainable mobility
Flexible choice of the number of vacation days and the amount of your variable salary share
Targeted and individual development opportunities

This is what you can expect:

System stability: As part of our IT operations team, you are responsible for the smooth operation of the congstar systems.
Monitoring professional: You are actively driving forward the continuous improvement of our monitoring landscape and the derivation of smart recommendations for action.
DevOps on equal footing: You discuss robustness and performance directly with the developers and also get involved in the core system yourself.
Automation power: You automate recurring tasks confidently and further develop our tooling together with your team.
Team DNA: A super-motivated environment, flexible working and mutual support are the framework in which you can fully develop.

This is what you have in your luggage:

Background: You have a degree with an IT focus or a comparable education as well as several years of practical experience in the IT environment.
Technology base: You feel absolutely comfortable with Linux and SQL and know exactly what stable operation means for our Oracle database and Java apps.
Developer gen: Java and web applications are your home — ideally, you have already gained experience in developing tools yourself using Java.
Solution mindset: Complex problems challenge you; you think pragmatically, goal-oriented and want to make a difference in a dynamic team.
Team spirit: You appreciate professional exchange and enjoy finding the best solution together — even if the idea doesn't come from you.

This position is also available on a part-time basis.

Severely disabled people are given priority if they are equally qualified.
