• Excellent communication skills in English and Portuguese (Spanish is a plus).

Responsibilities

• Design, implement, and optimize LLM-based AI solutions for industrial and mining use cases.
• Develop data-driven pipelines for processing, transforming, and analyzing large-scale operational data from IoT sensors, edge devices, and cloud platforms.
• Fine-tune and deploy transformer-based architectures (GPT, BERT, Llama, T5, etc.) for domain-specific AI applications.
• Implement real-time AI inference models at the edge and in the cloud to support mission-critical decision-making.
• Optimize model performance, latency, and cost efficiency through techniques such as quantization, pruning, and distillation.
• Collaborate with data engineers and DevOps teams to integrate AI models into production-grade environments using MLOps best practices.
• Leverage vector databases (e.g., Pinecone, FAISS, Weaviate) for efficient retrieval-augmented generation (RAG) workflows.
• Develop and maintain APIs and microservices to expose AI models for real-time industrial applications.
• Ensure AI model security, explainability, compliance, and ethical considerations in line with regulatory frameworks such as ISO 27001 and IEC 62443.
• Automate ML workflows, including model training, validation, and deployment.
