Job description

  • Develop and deploy machine learning models to enhance our disinformation detection.
  • Work with large datasets to train and validate models using Python and popular machine learning libraries.
  • Collaborate with data engineers to ensure data integrity and efficient data pipelines.
  • Integrate machine learning algorithms into existing web applications and services.
  • Participate in cross-functional teams to define, design, and ship new machine learning features.
  • Conduct code reviews and enhance the machine learning development process.
  • Troubleshoot, debug, and upgrade machine learning systems.
  • Write clean, efficient, and maintainable code while implementing security and data protection.

Requirements

Do you have experience in Python?, Do you have a Master’s degree?, We are looking for Machine Learning Engineer with a minimum of two years expertise in Python and multimodal multi-agentic RAG., * Programming Language: Python, C++/Rust (optional)

  • ML/DL Frameworks: PyTorch (Preferred), Hugging Face (Transformers, Datasets, Tokenizers)
  • Data Processing: Pandas, NumPy

Generative AI & LLMs

  • LLM Orchestration (RAG): LangChain, LangGraph, LlamaIndex or similar
  • Vector Databases: Qdrant, FAISS, or similar
  • Fine-Tuning: Experience with fine-tuning techniques (e.g., PEFT, LoRA, QLoRA) on open-source models (e.g., Llama, Mistral), alignment-tuning (e.g. DPO, ORPO).
  • APIs: OpenAI, Anthropic, Gemini, etc.
  • Inference: vLLM, llama.cpp, SGLang, etc.

MLOps & Deployment

  • Containerization: Docker
