Our employees say:
We work in an exciting industry and OOC is a company that focuses on growing its services and empowering its people to reach their potential. One of the many reasons I enjoy my work is the strong alignment between the environment at OOC and my personal values. Our culture thrives on constantly improving and achieving above average results.
I felt completely at ease at OOC right from the start – especially this humanity is no longer so common in everyday working life. In addition, OOC gives me the opportunity to further my education in many areas and to get to know new fields of work.
OOC gives me the variety that makes a job exciting – and in a relaxed working atmosphere! Every new project or new assignment brings challenges that advance you personally as well as professionally!
OOC offers me exciting and varied work. The different projects always bring new challenges – but we have a great team that supports each other and masters everything together!
I am happy to be part of the team! OOC gives me freedom to develop and supports my self-realisation process.
OOC is a company that understands the needs of the customer and implements them efficiently and effectively, but always keeps the focus on us employees. Thanks to OOC, I was even able to complete a full-time training course! Not every company does that nowadays…
Although I have only been with the company for a short time, I am proud to be part of Onken Offshore and to complement the team with my skills as a troubleshooter and service technician in the wind turbine sector! In addition, I get the opportunity to further my education in other areas and to broaden my horizons.
