Embedded UI Designer / Engineer

We’re hiring an Embedded UI Designer/Engineer to build high‑performance, reliable HMIs for industrial controllers. You’ll design and implement UI screens on resource-constrained targets (MCUs/SoCs with RTOS or bare‑metal), and contribute to lightweight web tools (for configuration, dashboards, simulators). You’ll collaborate with product/UX/firmware to ship UIs that are responsive, memory‑efficient, and consistent across device and web.

Embedded UI (Primary)

• Design and implement UI screens and widgets for industrial controller HMIs on MCUs/SoCs (e.g., STM32, NXP, ESP32, Atmel AVR, Microchip PIC ).
• Build event-driven UIs with change-driven refresh (avoid unnecessary redraws; respect tight periodic loops, e.g., ~100–200 ms).
• Implement robust navigation/state machines, deinit/teardown patterns, and memory-safe handling to prevent leaks and fragmentation.
• Optimize rendering: dirty-rect invalidation, double-buffering, draw callbacks; tune for frame budget and startup time.
• Implement localization/internationalization (i18n/l10n) including dynamic language switching and font pipeline management.
• Integrate UI with firmware data contracts; handle alarms, trends, diagnostics, and service/maintenance flows common to industrial HMIs.

Web (Secondary)

• Build complementary web utilities (configuration portal, remote dashboard, or UI simulator) using any modern stack.
• React is a nice‑to‑have (TypeScript preferred), but Angular/Vue or other modern stacks are welcome.
• Integrate with device APIs (REST/WebSocket/MQTT); emulate device states; handle offline/retry scenarios gracefully.Contribute to a shared design system (tokens, components) for visual consistency across device + web.
• Write documentation (UI architecture, screen contracts, localization guidelines) and participate in design/code reviews.

Experience building embedded UIs (C/C++; LVGL/Qt/QML/TouchGFX/Crank Storyboard or similar)

• 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.); solid HTML/CSS/JS/TS fundamentals.
• Tooling: Git, CMake, GCC/Clang, JTAG/SWD debug, performance profiling; Node.js toolchains for web builds.
• Excellent debugging, documentation, and cross-functional collaboration skills.

• Knowledge on Agile / Scrum driven teamwork.
• React + TypeScript; component libraries and state management (Redux/Zustand/Signals).
• RTOS experience (FreeRTOS/Zephyr), DMA/cache considerations for display pipelines.
• Industrial protocols & environments: Modbus (RTU/TCP), CAN/CANopen, RS‑485, OPC UA, Ethernet/IP, PROFINET.
• Graphics fundamentals: color formats, alpha blending, anti‑aliasing, render budgeting, tearing mitigation.
• CI/CD for embedded and web; automated UI checks (screenshot diffs, basic e2e).
• Experience with safety, reliability, and diagnostics patterns in industrial HMIs.
