The primary role involves designing and implementing high-performance UI screens and widgets for industrial controller HMIs running on resource-constrained MCUs/SoCs, focusing on responsiveness and memory efficiency. Secondary responsibilities include building complementary web utilities for configuration or simulation and contributing to a shared design system for visual consistency.
Responsibilities
- Design and implement UI screens and widgets for industrial controller HMIs
- Build event-driven UIs with change-driven refresh
- Implement robust navigation/state machines, deinit/teardown patterns, and memory-safe handling
- Optimize rendering: dirty-rect invalidation, double-buffering, draw callbacks
- Integrate UI with firmware data contracts
Requirements
- 5-6 years of experience building embedded UIs (C/C++; LVGL/Qt/QML/TouchGFX/Crank Storyboard or similar)
- Strong understanding of event-driven programming, partial/dirty region redraws, and double-buffering
- Localization/i18n experience, including font handling (Unicode, fallbacks, multi-script)
- Web experience with modern front-end (any of React/Angular/Vue/Svelte, etc.)
