Graphical User Interface & Full Stack Software Developer - Quantum Platform

About the role

Keysight Technologies' QES division is seeking a highly skilled GUI & Full Stack Software Developer to design and develop desktop-focused graphical user interfaces (with web capability as a secondary option) supporting quantum automation, data management & analysis, and system configuration & operation. You will collaborate across a multidisciplinary engineering environment-including physicists, firmware engineers, and backend developers-to implement intuitive user interfaces, data workflows, and backend services that power Keysight's quantum control platform. While desktop GUI development is preferred, candidates with strong full stack experience will help extend our platform with web-compatible components, backend services, and scalable system integrations.

Responsibilities

• Design, implement, and maintain desktop GUIs for automation workflows, data visualization/analysis, instrument control, and system configuration.
• Develop full stack components-including backend services (Node.js, GoLang), APIs, and front-end web interfaces (Angular, TypeScript)-to support cross-platform tooling and integration where appropriate.
• Collaborate with users and product owners to translate complex quantum workflows into intuitive UI/UX designs, mockups, and prototypes.
• Build reusable UI and application frameworks that support long-term maintainability, extensibility, and performance.
• Integrate GUIs with hardware-control layers, quantum SDKs, and backend orchestration systems through well-defined APIs.
• Develop robust testing strategies including unit, integration, functional, and UI automation tests; work with QA to ensure system-level reliability.
• Implement data visualization and data-management interfaces for experiment results, logs, metadata, and system performance analytics.
• Contribute to architectural decisions involving UI technologies, backend frameworks, IPC/communication patterns, and deployment models.
• Participate in code reviews, design reviews, and technical discussions, ensuring consistency and quality across the team.
• Document UI workflows, software interfaces, and system interaction models.
• Collaborate effectively across multidisciplinary engineering teams, including Core OS, and Platform Engineering groups.

Requirements

• BS/MS in Computer Science, Software Engineering, or a related technical field.
• Strong experience building desktop GUI applications (Qt, PyQt/PySide, .NET/C#, or similar frameworks).
• Proficiency in full stack development, including TypeScript, Angular (or comparable front-end frameworks), Node.js, GoLang
• Ability to design, build, and maintain RESTful APIs, backend microservices, or orchestration layers.
• Solid understanding of UI/UX principles, user workflow design, data visualization, and responsive interface patterns.
• Experience integrating front-end applications with hardware control systems, real-time data pipelines, or scientific instrumentation.
• Strong debugging and troubleshooting skills across the UI ↔ backend ↔ hardware boundary.
• Excellent verbal and written communication skills.
• Highly organized, detail-oriented, and comfortable working in a dynamic R&D environment with evolving requirements.
• Preferred / Nice-to-Have:
• Experience with graphical workflows for scientific, engineering, or data acquisition systems.
• Experience designing cloud-compatible UIs or hybrid desktop/web interfaces (Electron, embedded browsers, etc.).
• Familiarity with Keysight instrumentation, PXI systems, or real-time measurement workflows.
• Understanding of quantum computing or willingness to rapidly learn quantum concepts.
• Experience with CI/CD pipelines, UI automation frameworks, or end-to-end testing systems.
