IT Security Consultant (m/f/d)

You want to work in a young, dynamic and internationally operating team and contribute your expertise in the field of IT security?
You like to work independently on varied and exciting tasks and are interested in proving your knowledge every day?


By the way: Our job advertisements are mostly quite sporadic in terms of requirements or qualifications, as we are basically not looking for a personnel resource, but for a good addition to our existing team. Qualifications, professional experience and specializations are of secondary importance for the time being. Because we specialize in penetration testing, we generally find it easy to provide further training or to promote specialist skills.

Achieve more together

As an independent consultancy, we specialize in performing penetration tests. We support companies with any technical, organizational or cultural IT security challenge.

Creative minds, a breath of fresh air and bold ideas ensure that we are always finding new ways to protect companies from cyber attacks in creative ways. We attach great importance to the individual support of our customers and colleagues. What counts for us: Attractive remuneration, a lot of passion and team spirit, cooperation at eye level and with flat hierarchies, constantly new challenges. What counts for us is joint success, everyone pitches in, everyone has fun and learns something new every day.

People come to us who like to go the extra mile, who want to push themselves, who want to grow every day, who love new challenges and variety. Those who are looking for team spirit and need flexibility in organization, who don’t want to be just a cog in the wheel, stay with us. Someone who has a desire to get really good at what they do. A real KALWEIT ITS team player!
