What You Will Do  
The Principal Digital Factory UX/UI Test Engineer leads UI/UX design, front-end testing, usability validation, and regression automation for Ignition-based applications, MES workflows, dashboards, and IIoT-enabled systems. The engineer partners with manufacturing engineers, software developers, and stakeholders to design intuitive user interfaces, validate operator workflows, prevent defects, and establish department-wide testing standards.

• 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.

Front-End Testing & Validation

• 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.

Testing Standards & Department Best Practices

• 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 DevOps 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 DevOps pipelines and ensure consistent operation before releases.

What You Will Learn

• 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.

Qualifications You Must Have 

• 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.

Qualifications We Prefer

• Experience using Azure DevOps (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 (Selenium, Playwright, Robot Framework).
• Experience establishing testing standards or leading testing initiatives in engineering organizations.
• Experience with Ignition, MES systems, IIoT connectivity, or digital factory applications.
• Familiarity with manufacturing workflows, operator interfaces, and plant floor digital systems.
