Embedded UI / Graphics Engineer

About the Role

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.

You'll work on:

• Embedded UI architecture
• Character animations and state transitions
• Sprite, bitmap and font pipelines
• Rendering optimization (dirty rectangles, partial redraws, partial refresh)
• Display and hardware trade-offs
• Integrating Git activity, build status and notifications into the UI

We're looking for someone with experience in:

• C/C++
• Embedded graphics
• LVGL, U8g2, TFT_eSPI, Adafruit GFX or similar
• OLED, TFT or e-paper displays
• ESP32, STM32 or similar MCUs

Side projects are absolutely welcome—we care more about what you've built than where you've worked.

Contract

~10–15 hrs/week for approximately 6–8 weeks, with the possibility of ongoing collaboration.
