What makes Smile special

Smile is the largest online insurer in Switzerland – and we are continuously growing. ? That is why we are constantly looking for new people who want to continue this journey with us. Being a Smiler does not mean being run-of-the-mill, but being involved with heart and passion. With just under 80 employees, we are relatively small, and that is exactly why every voice counts even more with us. This way, you can make more of a difference here than elsewhere. And because genuine relationships matter to us, aperitifs are just as important as honest feedback and transparency. Insurance does not have to be boring. We are curious, technology-enthusiastic, and open to detours – as long as we learn from them. Short decision-making paths are just as much a part of us as the opportunity to contribute quickly: creatively, boldly, and across team boundaries. And the best part: despite start-up vibes, you benefit from the stability and advantages of a large company. As a 100% subsidiary of Helvetia Insurance, we have a strong employer behind us.
