The Connected Factory Intelligence (CFI) department develops, deploys, and enhances digital factory solutions that enable modern, data-driven manufacturing. We are seeking a Principal Digital Factory UX/UI Test Engineer to serve as the UI/UX design authority and front-end test expert for our digital manufacturing applications. This role drives the creation of intuitive operator experiences, validates front-end functionality, establishes test best practices, and builds regression test automation that ensures reliable, high-quality releases.

• UI/UX Design Leadership
• Lead the design of modern, intuitive UI/UX for Ignition screens, MES workflows, dashboards, and digital factory applications.
• Develop wireframes, prototypes, and final layouts using tools such as Figma and Ignition Designer.
• Establish consistent UX patterns, visual standards, and interaction guidelines for all CFI applications.
• Collaborate closely with engineers and stakeholders to ensure designs align with operator needs and manufacturing workflows.

• Own the front-end testing strategy for digital factory applications across CFI.
• Develop and execute structured test plans for usability, workflow accuracy, interface clarity, error-handling behavior, and navigation flow.
• Validate implementation fidelity between UX designs and deployed features.
• Conduct iterative UI/UX reviews and acceptance testing to prevent defects from entering production environments.

• Define testing best practices, templates, and guidelines for software engineers and stakeholders.
• Establish test case documentation standards, release readiness expectations, and UX validation processes.
• Train engineers on testing fundamentals, Azure Dev Ops workflows, defect triage, and UI/UX acceptance criteria.
• Automated Regression Testing
• Build and maintain automated regression tests focused on front-end interactions, click-path validation, and navigation behavior.
• Use tools such as Selenium, Playwright, or similar Python-based automation frameworks to simulate user workflows.
• Integrate automated tests into Azure Dev Ops pipelines and ensure consistent operation before releases.

• Opportunities to lead UI/UX strategy and testing modernization across CFI.
• Exposure to Industry 4.0 technologies, digital manufacturing innovation, and advanced automation.
• Leadership experience shaping how future digital factory applications are designed, validated, and deployed.
• Mentoring and collaboration across cross-functional engineering and operations teams.

• Typically requires a degree in Science, Technology, Engineering or Mathematics (STEM) and a minimum of 8 years of prior relevant experience unless prohibited by local laws/regulations.
• 8+ years of experience in UI/UX design, front-end testing, human-machine interfaces, or digital manufacturing systems.
• Experience designing user-centric interfaces using Figma, Ignition, or similar tools.
• Experience in front-end testing, UX validation, and test plan development.

• Experience using Azure Dev Ops (or similar tools) for test management and defect tracking.
• Proficiency with Python and SQL for lightweight automation and validation scripting.
• Experience with automated UI testing tools…
