About PTA GmbH

PTA GmbH is one of Germany's oldest, family-run IT and management consultancies, founded in 1969. With 13 locations across Germany, Switzerland, and Spain, we support clients with IT and organizational projects across all industries and technologies, remaining financially and manufacturer-independent.

We integrate AI-based tools where they provide real added value – with professional diligence, a critical perspective, and the conviction that technological advancement is part of our daily consulting work.

We operate with flat hierarchies and organize into Business Units focused on technical specialization and targeted employee development.

Since our founding, we've prioritized working close to our locations whenever possible to maintain a good work-life balance, allowing time for family and hobbies. Combined with a hybrid work concept – remote, on-site at the client's, and in the office – and flexible working hours, we support the balance between work and leisure.
