Senior Software Engineer – SaaS Platform & Architecture (Java / Angular)

About us

Sumex AG was founded in 2019 and emerged from the long-standing collaboration between ELCA Informatik AG and Suva. In 2022, we merged with Secon AG to become a leading provider of ERP and claims management software for the Swiss healthcare sector. Our goal is to reduce complexity, ensure compliance, and increase efficiency through the automation of standard processes in insurance. Our privately owned company, headquartered in Zurich, employs more than 50 experts who serve customers throughout Switzerland.

Shape the future of our SaaS platform with us.
