Our Strengths

Innovative technologies. Future-ready products. Team spirit.

We develop cybersecurity solutions for critical infrastructures. We are looking for dedicated people who collaborate across teams, take ownership, and are eager to develop professionally and personally.

Personal responsibility

At ECOS, you can actively shape your work—in terms of responsibilities, schedule, and location. We believe in trust, clear goals, and people who take ownership of their work.

Professional development

Cybersecurity requires constant innovation. That’s why we encourage learning, knowledge sharing, and professional growth—within teams, through projects, and by taking on new challenges.

Team spirit

Security is a team effort. From the initial idea and development to implementation at customer sites, we work across teams, focus on solutions, and stay closely connected.

A glimpse into our daily work

Exploring new ideas together, sharing knowledge, and developing solutions as a team is what collaboration at ECOS is all about.

Open collaboration

Engineering and Sales work hand in hand. This close collaboration enables us to develop tailored solutions for our customers.
 

Taking responsibility

All products undergo rigorous testing before release. Delivering secure products requires a strong sense of responsibility across all areas of the company.

Making an impact together
