Lopaka is a browser-based UI editor and C/C++ code generator for embedded displays (OLED, TFT, e-paper). Around 20,000 hardware developers use it to design interfaces for ESP32, STM32, AVR, Arduino and other platforms. We're building DevPet, a small animated desktop companion for developers (think Tamagotchi meets build monitor). We're looking for an experienced embedded UI engineer to help design the UI architecture and build a polished animated interface that runs within tight memory and performance constraints.
