Software Engineer Intern - UI Development & Data Visualization

We are looking for a Software Engineering Intern to join the team developing Keysight’s circuit and multiphysics simulation platform. Circuit designers use our desktop application to set up, run and analyze complex simulations and to explore and optimize their designs. The user interface is built in Python using Qt/PySide6, while our plotting engine is written in Rust. We are progressively moving more performance-critical UI functionality to Rust.

A key focus of this internship will be live visualization, including simulation results, optimization progress and waveforms that update while simulations are running.

What you’ll do:

• Build and enhance live, streaming visualizations that update while simulations or optimizations are running, including sweep results, optimizer convergence, eye diagrams and spectra.
• Develop interactive engineering charts, such as XY, polar, Smith, parallel-coordinate and histogram plots.
• Implement markers, readouts and smooth interactions for large engineering datasets.
• Contribute to advanced, performance-critical UI features, including Keysight’s in-house plotting engine.
• Support the evolution of the UI architecture, including separation from the simulation backend, responsive asynchronous data flows, reusable components and consistent application behavior.
• Build complex editors and tables using the Qt model/view framework.
• Develop automated tests to maintain a robust, reliable and maintainable user interface.

• Currently pursuing a bachelor’s or master’s degree in Computer Science, Computer Engineering, Software Engineering or a related field.
• Experience developing software in Python.
• Experience with desktop UI development, ideally using Qt, PySide6, PyQt or C++ Qt.
• Understanding of asynchronous or real-time data processing in user interfaces, including threads, streaming data and maintaining UI responsiveness.
• Familiarity with automated testing and maintainable software-development practices.
• Fluent English. German language skills are an advantage.

Strongly preferred:

• Experience with C++.
• Experience with Rust, or a strong interest in learning Rust.

Nice to have:

• Knowledge of RF/microwave engineering, signal integrity, circuit simulation, test and measurement, or electronic design automation.
• Experience with rendering technologies such as GPU rendering, OpenGL or wgpu, or with custom plotting engines.
• Experience using AI-assisted development tools within a code-review workflow.
