About The Position

Keysight is at the forefront of technology innovation, delivering breakthroughs and trusted insights in electronic design, simulation, prototyping, test, manufacturing, and optimization. Our ~16,800 employees create world-class solutions in communications, 5G, automotive, energy, quantum, aerospace, defense, and semiconductor markets for customers in over 100 countries. Our award-winning culture embraces a bold vision of where technology can take us and a passion for tackling challenging problems with industry-first solutions. We believe that when people feel a sense of belonging, they can be more creative, innovative, and thrive at all points in their careers. About the Role We're looking for an experienced WPF GUI Engineer to design and build the user interface for our real-time digital oscilloscope platform. You'll own the software layer responsible for rendering high-speed waveform data, live measurements, and instrument controls on embedded Windows hardware.

Requirements

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
Strong debugging and profiling skills for latency, frame timing, and memory usage in long-running applications

Nice To Haves

Experience with user interface technologies such as QT or Avalonia
Experience with SciChart graphical software
Familiarity with oscilloscope concepts: triggering, sampling theory, FFT/spectral display
Experience with GPU-accelerated rendering (DirectX, SharpDX, Vortice.Windows, or similar)
Familiarity with Windows IoT Enterprise or embedded Windows deployment for instrument-grade hardware
Exposure to industry-standard remote instrument control protocols (SCPI, VISA, LXI)
Experience interfacing with embedded acquisition hardware (FPGA, ADC front-ends, or similar) via shared memory, DMA buffers, or custom drivers

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
