S-IT
Complex engineering systems are not created by technology alone, but by people who understand complex interrelations and take responsibility.
S-IT combines system expertise, process-oriented thinking, and software development to create viable solutions. We support custom applications throughout their entire lifecycle – from requirements analysis to stable operation – and take a holistic view of systems throughout their use.
Our team combines technical expertise with close collaboration. Open communication, professional curiosity, and a strong commitment to quality shape our daily work. We approach challenges in a structured and solution-oriented manner.
Located in Weissach, approximately 25 kilometres northwest of Stuttgart, we are firmly rooted in the technological landscape of the Stuttgart region. Our close connection to development and industrial practice shapes our ambition to create sustainable and future-ready engineering environments.
Our Vision
S-IT is the leading wiring harness process and IT expert. We combine innovative consulting with scalable software solutions to digitalize, automate, and optimize the entire wiring harness lifecycle. Our vision is a collaborative, long-term partnership that offers innovation, quality and economic efficiency for our customers – and thereby helps maintain the long-term competitiveness of Europe's industrial base.
Our Values
Trust
We trust in the abilities and reliability of our coworkers and believe that they act in accordance with our values and build relationships based on honesty and mutual respect.
Sense
To know the “why” gives us orientation, helps to create values together and to recognize each person's contribution as valuable.
Responsibility
We take action, make decisions within our expertise and take responsibility for the consequences, even if they are uncomfortable.
Openness
We listen carefully and make room for every idea, perspective and person. We use changes as chances to grow together and to improve.
Engagement
We chase goals with passion and engagement. We actively define our own spheres of action and personally contribute beyond that.
Reflection
We take time to reflect, provide appreciative feedback, and honestly reflect on ourselves so that we can grow together and learn from our experiences.
Solidarity
look out for one another, support each other and hold on together, even in tough times. We not only work for another, but we more act with each other.
