Job summary

Keysight is seeking an experienced WPF GUI Engineer to design and build the user interface for a real-time oscilloscope platform on embedded Windows hardware.

You will own the software layer for rendering high-speed waveform data, live measurements, and instrument controls, while implementing MVVM architecture to separate data models from rendering and control logic.

Qualifications

• 5+ years of professional experience building WPF applications for desktop or embedded Windows environments.
• Strong proficiency in C# and .NET, with experience in performance-critical, real-time-adjacent UI code.
• Deep understanding of MVVM, data binding, dependency properties, and custom control/template development in XAML.
• Solid grasp of multithreading and producer/consumer patterns for handling continuous data acquisition feeds without blocking the UI thread.

Responsibilities

• Design and implement WPF interfaces for real-time waveform display, including live trace rendering, persistence modes, and multi-channel overlays.
• Implement instrument-control UI: trigger configuration, timebase/voltage scaling, channel setup, cursors, and automated measurements (rise time, frequency, amplitude, etc.).
• Design UI behavior for deep memory acquisition, waveform decimation/downsampling for display, and zoom/pan across captured records.
• Build touch- and knob/encoder-friendly interfaces for front-panel hardware controls alongside on-screen UI.
• Ensure UI stability and responsiveness during sustained real-time operation (hours/days of continuous capture).
• Implement MVVM architecture that cleanly separates acquisition data models from rendering and control logic.
