As a Software Engineering Intern – Device Simulation & Digital Twin , you will help us rebuild and significantly expand the software simulator for our DICENTIS conference devices . The simulator acts like real hardware on the network, allowing our development and test teams to validate server behavior, run automated regression tests, and develop software without always needing access to physical devices. We already have an existing simulator, but it currently covers only a limited set of device behaviors and runs on an aging technology stack. Your project will be to rebuild it using a newer technology foundation that we are already investing in, while expanding its coverage from approximately 30% to 80–90% of real device behavior . You will work on a long-term project with a tangible impact on how our engineering teams develop, test, and maintain our products. The final solution will run on both Windows and Linux and become an important part of our automated testing and development environment. 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.
