Your development counts

The strength of Sioux is in our people. We therefore find it important to support you optimally in your development. Our people managers are there for you to facilitate you in this process. They have a technical background and they know what is needed to take a next step, keep you focused and challenge you. In this manner you will discover how you can grow in your field, for example by doing workshops and go to trainings, but also by meeting new challenges in our projects.

The Source Program

Sharing knowledge is in our DNA. Our employees are happy to share their technical knowledge and experience with each other. In The Source Program we link experienced engineers with colleagues just starting their careers. This way you can learn a lot from your own colleagues.

Up-to-date with 6,000 EUR a year

Every employee also has access to a large development budget, to gain even more knowledge and expand their growth.

'At Sioux, you will receive a personal development budget. We do not work with fixed training courses', says Dirk De Bruycker, responsible for people management at Sioux. 'Your current competencies and ambitions will determine which courses you will follow. And whether it's technical knowledge or personal skills you’re looking for, with a budget of 6,000 EUR per year, it will not be hard to work on your development.'

Together, we are Sioux

Sioux consists of committed, enthusiastic people. To strengthen mutual contact, bonding and sociability, we regularly organize activities. Not only for you as an employee, but also your family and/or partner are welcome.
