Machine Learning Engineer, LLM Training & Customization (Remote)

What You'll Do

• Train and fine-tune Large Language Models (LLMs) based on client domains and industry-specific data.
• Design, develop, and optimize custom AI workflows that integrate LLMs into production environments.
• Utilize LangChain, CrewAI, and LangFlow to orchestrate complex LLM-based applications.
• Implement and optimize retrieval-augmented generation (RAG) techniques for better contextual responses.
• Work on data preparation pipelines, including tokenization, augmentation, and embedding optimizations.
• Develop scalable and efficient inference pipelines for deploying LLMs in production.
• Collaborate with software engineers to integrate AI models into real-world applications.
• Optimize model performance, latency, and cost to ensure smooth deployment at scale.
• Research and experiment with cutting-edge AI advancements in LLM fine-tuning and prompt engineering.

What You'll Bring

• 3+ years of experience in Machine Learning & NLP, with a focus on LLM training and deployment.
• Experience with LLM fine-tuning techniques such as LoRA, PEFT, and instruction tuning.
• Proficiency in Python, PyTorch, TensorFlow, and Hugging Face Transformers.
• Hands-on experience with LangChain, CrewAI, and LangFlow (bonus points for deep expertise).
• Strong understanding of vector databases (Pinecone, Weaviate, FAISS) and embedding models.
• Experience building production-ready AI products, ensuring scalability and reliability.
• Deep knowledge of prompt engineering, tokenization strategies, and data augmentation for LLMs.
• Familiarity with ML-Ops best practices, cloud-based AI deployments, and GPU optimizations.
• A passion for AI-driven automation, custom model development, and pushing the boundaries of LLM capabilities.

Bonus Points

• Experience deploying LLMs in low-latency, real-time environments.
• Strong background in serverless AI architectures and containerized deployments.
• Hands-on experience with Kubernetes, Docker, and cloud-based ML workflows (AWS/GCP/Azure).
• Knowledge of speech-to-text (STT), text-to-speech (TTS), or conversational AI.
