Position: SENIOR C++ RENDERING ENGINEER (OPENGL, GPU)

Location: Finland

We are looking for a Senior C++ Rendering Engineer to work on a custom native rendering solution for an automotive project. The main task is to replace an existing MapLibre-based renderer with an in-house implementation written in C++ using OpenGL.

The role involves working close to the rendering pipeline, shaders, and GPU, as well as understanding an existing Android/Kotlin implementation and reproducing the same behavior in a native architecture.  

• Strong professional experience with C++, especially in performance-sensitive or low-level systems
• Good understanding of memory management, ownership, and object lifetime in C++
• Practical experience with OpenGL and writing/debugging GLSL shaders
• Understanding of how rendering pipelines work and how responsibilities are split between CPU and GPU
• Experience debugging non-trivial rendering issues (for example incorrect pipeline state, shader problems, or data flow issues)
• Experience working in Linux / Ubuntu environments
• Comfortable working with existing codebases and re-implementing functionality in a new architecture
• Able to reason about technical trade-offs and explain implementation decisions

WHAT YOU WILL DO:

• Implement a native rendering solution in C++ using OpenGL
• Write, adjust, and debug GLSL shaders
• Replace the current MapLibre-based renderer with a custom implementation
• Review existing Android/Kotlin code to understand current behavior and replicate it in native code
• Debug rendering issues across the graphics stack (application logic, OpenGL state, shaders, GPU behavior)
• Optimize rendering performance and memory usage, moving work from CPU to GPU where appropriate
• Work with other engineers to align rendering behavior with system and application logic
•  

• Experience with Vulkan or other low-level graphics APIs
• Background in GPU performance optimization and profiling
• Familiarity with Android development (Kotlin) to better understand the existing implementation
• Experience with mapping, geospatial visualization, or automotive UI systems
• Knowledge of MapLibre, Mapbox, or similar frameworks
• Experience with real-time or performance-critical rendering systems
• Understanding of multi-threaded rendering architectures
