Software Engineering Intern – Device Simulation & Digital Twin (February 2027)

During your internship, you will:

• Get familiar with the existing device simulator, DICENTIS devices, and the newer technology stack used for the rebuild.
• Analyze the behavior and capabilities of real devices and identify which scenarios are already simulated and which are still missing.
• Define and prioritize the device behaviors required to significantly expand simulator coverage.
• Design and implement new simulated device scenarios using C# and/or C++.
• Develop software that communicates over the network and behaves like the corresponding physical devices.
• Make the simulator compatible with both Windows and Linux.
• Develop and maintain automated tests that use the simulator as a replacement for physical hardware.
• Integrate the simulator into our automated build and test pipeline, including continuous integration where applicable.
• Document supported device behaviors, architecture, usage, and known limitations.
• Work closely with engineers and testers to understand their needs and ensure the simulator is practical for everyday development and testing.
• Break down a long-term project into manageable milestones and provide regular progress updates to your supervising team.

• You are currently pursuing a Bachelor's or Master's degree in Computer Science, Computer Engineering, Electrical/Electronic Engineering, or a related technical field.
• Solid programming skills in C# and/or C++.
• Good understanding of object-oriented programming and software design principles.
• Basic understanding of networking concepts such as TCP/IP, client-server communication, and networked devices.
• Ability to work independently, take ownership of tasks, and break down a larger project into manageable steps.
• Good written and spoken English communication skills.
• Motivation to learn, investigate technical problems, and develop a solution from an existing foundation.

It is a plus if you have:

• Experience with .NET or .NET Core.
• Familiarity with network protocols or device communication standards.
• Experience with automated testing or continuous integration tools such as Jenkins.
• Experience working in a Linux-based development environment.
• Coursework or project experience in software engineering, networking, embedded systems, or distributed systems.
