• Utilize UI frameworks and graphics libraries (e.g., LVGL or equivalent).
• Apply human-machine interface (HMI) and human factors engineering principles to UI design.
• Optimize interfaces for gloved operation, limited visibility environments, and rapid decision-making under stress.
• Validate usability through operator feedback, simulations, and test events.
• Collaborate with QA and Systems Engineering to validate UI behavior under high system load, network degradation, and fault and failover scenarios.
• Support integration testing with hardware, voice subsystems, and backend services.
• Participate in design reviews, sprint demos, and formal verification activities.
• Produce UI design documentation, interaction models, and developer guidelines.
• Participate in Agile ceremonies, design reviews, and cross-disciplinary technical discussions.
