AI Engineer - Remote Friendly (Poland)

Emporix is an AI-driven Autonomous Commerce Execution Platform that gives enterprises full control over how their commerce works. It orchestrates operations end-to-end—so you can scale faster, respond smarter, and deliver better customer experiences. We are looking for a skilled AI Engineer (Machine Learning) to join our team in Poland, with hands-on experience in fine-tuning and deploying custom large and small language models (LLMs/SLMs) to production. In this role, you’ll build and optimize cutting-edge AI models that power intelligent commerce experiences. If you’re excited about production-grade AI, retrieval-augmented generation (RAG), and cloud-native ML engineering, we’d love to hear from you. You can work from our modern office in Gliwice or remotely from anywhere in Poland, with a visit to the office at least once per month to meet the team. What You’ll Be Doing LLM & SLM Development Fine-tune and optimize LLMs and SLMs on domain-specific datasets to enhance relevance and performance. Build and iterate on custom models tailored to business-specific needs and customer workflows. Evaluate models for accuracy, latency, cost, and robustness in real-world scenarios. RAG & System Integration Design and implement retrieval-augmented generation (RAG) pipelines. Work closely with backend engineers to integrate models into microservice-based systems via APIs and orchestration layers. Production-Grade ML Operations Deploy and monitor ML models in cloud environments such as GCP or equivalent platforms. Build scalable, reproducible training and inference pipelines using MLOps best practices. Track performance with monitoring, logging, and feedback loops for continuous improvement. Collaboration and Optimization Collaborate with AI developers, product managers, and domain experts to understand business use cases and translate them into ML solutions. Documentation Write and maintain clean, well-structured documentation for LLMs/SLM. Contribute to knowledge bases and architecture diagrams for long-term maintainability and onboarding. What We’re Looking For You have at least 3+ years of hands-on experience in machine learning, with a focus on NLP and language models. You have proven experience with LLM/SLM fine-tuning, training, and optimization, including LoRA, QLoRA, or similar techniques. You have a strong understanding of transformer architectures and experience with open-source models like Hugging Face, Mistral, LLaMA, or Gemma. You have designed and deployed RAG systems in production environments. You are proficient in Python, PyTorch, or TensorFlow, and feel at home with modern ML frameworks. You have experience operating ML models in cloud environments, ideally GCP. You can bridge the gap between research and engineering, experimenting fast but shipping stable, production-ready solutions. You have strong Polish and English communication skills (B2/C1 or above). Bonus Points (What Else Might Help You Succeed?) Familiarity with vector databases, embedding models, and semantic search. Experience with advanced frameworks like LangChain and LangGraph . A passion for exploring agentic AI and next-gen architectures. Why You’ll Love It Here Real Impact - Your work will directly power next-gen autonomous commerce experiences used by top-tier businesses. Cutting-Edge Technology - Work with advanced AI frameworks like LangChain and LangGraph, and bring LLM-driven features to production in a cloud-native environment. Autonomy and Innovation - Explore agentic AI, RAG systems, and next-gen architectures with the freedom to propose and test new ideas. Collaborative Culture - Join a team of talented professionals who value knowledge-sharing, open communication, and a passion for building exceptional systems. Impactful Contribution - Be part of a company where your work directly impacts the success of a next-generation commerce platform used by top-tier businesses. Flexible Work Setup - Enjoy a remote/hybrid work model that promotes flexibility and personal well-being while encouraging collaboration and meaningful team connections. Meet in our Gliwice office at least once a month . Come as you are - We are building an AI-driven future for commerce, and that requires a variety of perspectives.
