About the role
Chagible AI Lab is hiring a Machine Learning Engineer (AI / LLM Engineer) to design, fine-tune, and deploy large language models for real-world applications. You'll build RAG pipelines, implement LLM evaluation frameworks, optimize inference performance, and integrate AI models into web systems. This is a remote freelance contract role open to applicants in the Philippines, working 4 days per week with a stable, structured workload.
What you'll do
- Design, develop, and deploy machine learning models and fine-tune large language models (LLMs) for performance and accuracy
- Build and maintain data pipelines for model training and evaluation; implement RAG systems with embeddings and vector databases
- Design and implement LLM evaluation frameworks including hallucination detection and response scoring
- Conduct experiments to improve model outputs, reliability, and efficiency; monitor and continuously improve model performance
- Optimize inference speed, scalability, and cost efficiency; integrate AI models into web applications and internal tools
- Collaborate with data annotators and QA teams to refine training data and document model architecture and workflows
Requirements
- Strong proficiency in Python with hands-on experience in PyTorch or TensorFlow
- Solid understanding of transformer architectures, attention mechanisms, and LLM internals
- Experience fine-tuning LLMs using LoRA, PEFT, instruction tuning, or supervised fine-tuning (SFT)
- Hands-on experience building RAG systems, including embeddings, vector databases (Pinecone, Weaviate, FAISS), and retrieval pipelines
- Experience building LLM evaluation frameworks and deploying models via APIs with optimized inference performance
- Knowledge of distributed training, GPU utilization, and model optimization techniques
- Strong debugging skills for model behavior analysis and ability to design experiments and iterate based on empirical results
