Working alongside experienced professionals, you will be designing experiments, building scalable solutions, and contributing to cutting-edge AI systems, including those based on large language models (LLMs).

Your tasks

• Designing and developing generative AI solutions, e.g., deep learning, transformer architectures, dense retrieval, hybrid search

• Building and optimizing LLM-based systems, including Retrieval-Augmented Generation (RAG) solutions

• Developing and enhancing agentic AI systems, including tool-using agents

• Implementing and evaluating machine learning and AI models, including designing experiments and analyzing results

• Collaborating with cross-functional teams to deploy solutions into production environments

• Developing and maintaining ML pipelines and integrating models within cloud environments

Requirements

• Minimum 5 years of experience in AI/ML

• Experience in generative AI, e.g., deep learning, transformers, vector databases, and retrieval systems

• Strong programming skills in Python and experience with modern ML frameworks, e.g., PyTorch, JAX, DeepSpeed, or similar

• Hands-on experience with cloud platforms (AWS, Azure, or GCP)

• Experience implementing and evaluating large language model (LLM) solutions, including familiarity with evaluation frameworks, e.g., OpenAI Evals, HELM, LM Harness, or custom tools

• Previous work with RAG, tool-using agents, and agentic AI approaches (prompt engineering, context management, evaluation)

• Fluent English

• Residing in Poland required
