C++/Qt Developer with Python AI Experience

Responsibilities

• Design and develop desktop and industrial device applications in C++17 using the Qt framework.
• Fine-tune and embed LLM models (LoRA/QLoRA, llama.cpp, Hugging Face) directly into applications — including offline/edge deployments.
• Build and maintain FastAPI microservices as the bridge between AI outputs and our Laravel/Livewire web frontend.
• Propose and select the right model architecture for each client use-case (open-source vs. API vs. custom trained).
• Troubleshoot performance and integration issues across the full C++/Python stack.

Required Skills

• Senior-level C++ (C++14/17) and Qt framework — desktop and/or industrial SW background.
• Python with PyTorch and Hugging Face Transformers for LLM fine-tuning and inference.
• FastAPI for building production REST microservices.
• Experience with LoRA/QLoRA fine-tuning or local model deployment (llama.cpp, GGUF).
• Ability to work independently and deliver without close supervision.

Nice to Have

• Experience with embedded or edge AI deployments on industrial hardware.
• Familiarity with OPC-UA, Modbus or similar industrial protocols.
• Knowledge of Docker and GPU server setup for model training.
• EU/DACH timezone — CET ±2 h preferred.
