UI Software Engineer - WPF/.NET Desktop Applications

📍 Job Overview

Job Title: UI Software Engineer - WPF/.NET Desktop Applications

Company: Keysight Technologies, Inc.

Location: Colorado Springs, Colorado, United States

Job Type: Full-Time

Category: Software Engineering / UI Development

Date Posted: September 22, 2026

Experience Level: Mid-Senior Level (5+ years)

Remote Status: On-site

🚀 Role Summary

• Design and implement sophisticated WPF interfaces for real-time waveform display and instrument control on embedded Windows hardware.

• Own the software layer responsible for rendering high-speed waveform data, live measurements, and instrument controls on embedded Windows platforms.

• Ensure UI stability and responsiveness during sustained real-time operation, critical for instrument-grade applications.

• Develop robust MVVM architectures that effectively separate acquisition data models from rendering and control logic.

📝 Enhancement Note: While the raw job description focuses on UI engineering, the context of "real-time digital oscilloscope platform," "embedded Windows hardware," and "sustained real-time operation" strongly suggests a role requiring a deep understanding of performance-sensitive applications and potentially embedded systems integration. This is not a typical web UI role.

📈 Primary Responsibilities

• Design and implement WPF interfaces for real-time waveform display, encompassing live trace rendering, persistence modes, and multi-channel overlays.

• Develop instrument-control UI elements, including trigger configuration, timebase/voltage scaling, channel setup, cursor management, and automated measurements (e.g., rise time, frequency, amplitude).

• Engineer UI behavior for deep memory acquisition, waveform decimation/downsampling for efficient display, and seamless zoom/pan functionality across captured records.

• Create user interfaces that are optimized for both touch input and physical front-panel hardware controls (knobs, encoders).

• Guarantee UI stability and responsiveness during extended periods of continuous real-time operation (hours/days of capture).

• Implement and maintain a clean MVVM architecture to ensure separation of concerns between data acquisition models and user interface logic.

• Collaborate with hardware and firmware engineers to integrate software with embedded acquisition hardware.

📝 Enhancement Note: The responsibilities highlight a need for deep expertise in performance optimization within UI frameworks, particularly for handling high-frequency data streams and ensuring real-time responsiveness. This goes beyond standard UI development and touches on embedded systems and real-time data processing challenges.

🎓 Skills & Qualifications

Education: While not explicitly stated, a Bachelor's degree in Computer Science, Software Engineering, Electrical Engineering, or a related field is typically expected for roles requiring 5+ years of professional experience in complex software development.

Experience: 5+ years of professional experience in building WPF applications for desktop or embedded Windows environments.

Required Skills:

• Strong proficiency in C# and the .NET framework, with a focus on performance-critical, real-time-adjacent UI development.

• Deep understanding of the MVVM (Model-View-ViewModel) architectural pattern.

• Expertise in XAML, including data binding, dependency properties, and custom control/template development.

• Solid grasp of multithreading, asynchronous programming, and producer-consumer patterns for handling continuous data acquisition feeds without blocking the UI thread.

• Proven ability in debugging and profiling applications for latency, frame timing, and memory usage in long-running applications.

• Experience with performance-critical UI code and optimization techniques. Preferred Skills:

• Experience with alternative user interface technologies such as Qt or Avalonia.

• Familiarity with SciChart graphical software for high-performance charting.

• Understanding of oscilloscope concepts, including triggering, sampling theory, and FFT/spectral display.

• Experience with GPU-accelerated rendering techniques (e.g., DirectX, SharpDX, Vortice.Windows).

• Familiarity with Windows IoT Enterprise or embedded Windows deployment for instrument-grade hardware.

• Exposure to industry-standard remote instrument control protocols (e.g., SCPI, VISA, LXI).

• Experience interfacing with embedded acquisition hardware (e.g., FPGA, ADC front-ends) via shared memory, DMA buffers, or custom drivers.

📝 Enhancement Note: The "Preferred Qualifications" list is extensive and points towards a highly specialized role. Candidates with experience in embedded systems, hardware interaction, and specialized graphics rendering will have a significant advantage. The mention of specific protocols like SCPI and LXI indicates a need for understanding how instruments are controlled and communicate.

📊 Process & Systems Portfolio Requirements

Portfolio Essentials:

• Showcase of complex WPF applications demonstrating proficiency in MVVM, data binding, and custom XAML controls.

• Examples of performance-critical UI components, ideally involving real-time data rendering or high-throughput data handling.

• Projects that illustrate effective use of multithreading and asynchronous patterns to maintain UI responsiveness.

• Demonstrations of debugging and profiling techniques applied to identify and resolve performance bottlenecks in desktop applications.

• If applicable, examples of embedded Windows application development or interaction with hardware interfaces. Process Documentation:

• While not explicitly requested as a deliverable, candidates should be prepared to discuss their process for designing, developing, and optimizing complex UI features.

• Be ready to articulate how you approach performance analysis and iterative improvement of UI responsiveness and stability.

• Discuss strategies for managing large datasets or high-frequency data streams within a UI context.

📝 Enhancement Note: For this role, the portfolio should emphasize technical depth in WPF and .NET performance, rather than broad UI design. Demonstrating problem-solving skills for real-time data rendering and embedded system constraints will be crucial.
