    What’s better than working with a bunch of friends?

    SISCOG provides the best environment, making it much easier to learn, work and grow as it happens between friends and laughs.

    Some years ago, when I was fresh out of university, I embarked on my professional journey at SISCOG. As a newcomer to the working world, I was apprehensive. In a field where genuine care for employees can be a rare find, I quickly realized that I had made the right choice.

    SISCOG's commitment to encourage a healthy work environment stood out. From day one, SISCOG prioritized my well-being, offering more than a support system - a friendly shoulder, a family - that eased the transition into a first job. It's a place where our growth is not only encouraged but celebrated.

    Recently, I sought a fresh challenge in a different department, and SISCOG seamlessly provided the training and opportunities to help me excel in this new role. It's a testament to the dynamic and supportive culture that defines SISCOG - a place where our potential is nurtured, and our career can continually evolve.

    What I praise the most at SISCOG is its good and relaxed environment and playing with the best programming language! In addition to its great and rich history, SISCOG surrounds me with people that are always ready to help and foster curiosity.

    As a runner, I am also an enthusiast of SISCOG’s Running and Walking Club, and don´t miss an opportunity to recruit more runners.

    Just like many young people coming out of university, I also shared the fear of ending up in a boring position. I was especially concerned about the dreadful stories of friends who left college motivated only to find themselves disillusioned a few months later.

    Joining SISCOG was, in this context, a relief!

    I joined a recent and innovative project, where I found an excellent team, but also humble and with a great spirit of mutual help. I felt from the beginning that they trusted me and that I had the freedom to propose and explore my ideas.

    It has been a fantastic experience.

    Working at SISCOG means you can be yourself in a work environment that is positive and healthy. A significant quality since, after all, this is the place where you spend a great part of your day!

    As an operational researcher I have the opportunity to learn and apply a wide range of optimization approaches to solve interesting challenges that SISCOG faces in the transportation domain. 

    Also, I feel quite comfortable to further my studies thanks to the flexible work, hence creating more value for my own career.
