---base: /meta-keywords:meta-viewport: width=device-width, initial-scale=1.0--- Software Engineer – Industrial HMI, Control \& Infrastructure ( /NixOS) (m/w/d)=================================================================================About The Role--------------ZEEN Tech AG is an award\-winning Swiss startup revolutionizing the food industry with our next\-generation, water\-based frying and drying technology, which we export worldwide. As we grow rapidly, we're looking for passionate individuals to join us.Instead of relying on legacy, closed\-source PLC software, we build our machines' Human\-Machine Interface (HMI) and control systems ourselves: a modern stack running on a hardened NixOS base. From the control engine up to the operating system, the entire platform is built on free and open\-source software: deliberately so. No vendor lock\-in, no black boxes, and full control over every layer of the machine.We are looking for a Software Engineer to join our team and work alongside our existing Software Engineer. This is a hands\-on role: you will take over well\-defined parts of the control backend, the HMI, our NixOS machine fleet, and our internal server infrastructure, and progressively take on more ownership as you settle in. You will report to our Software Engineer, who owns the software architecture and will be your mentor. You will also collaborate closely with our mechanical and electrical engineers, the Production Team, and our Culinary Development team, who put the machines through real cooking tests.Key Responsibilities--------------------* **Backend \& Control ( ):** Help develop and maintain the machine's core "engine" written in . You will implement and extend the communication layer for our new industrial machines, using robust, scalable protocols (such as Modbus TCP or EtherCAT) to manage a growing network of drives, VFDs, and sensors.* **HMI Development ( /Slint):** Expand and polish the machine's touch\-screen interface, built with Slint,
