Job Description

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.

Qualifications

  • 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.
  • An interest in audio, conferencing technology, embedded systems, or connected devices.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
