Data Scientist with AI

Data Scientist with AI (B2B) We are looking for an experienced Data Scientist with AI to drive innovation by designing, developing, and deploying enterprise-grade Machine Learning and Generative AI solutions for our clients. About Devapo At Devapo, we focus on continuous self-development and acquiring new knowledge. If you are a fast learner, want to participate in international projects, are a team player, and can work independently — join us! We provide our clients with more than just code — we want to equip them with tools that allow their businesses to flourish. Our clients’ success is our success, which is why we ensure that everyone who creates Devapo has a long-term goal in mind. Key Responsibilities: • Lead end-to-end projects in traditional Data Science, Machine Learning, and cutting-edge Generative AI and Large Language Models (LLMs) — from research and experimentation to production deployment. • Design and implement scalable AI/ML pipelines and MLOps practices using cloud-native services (e.g., Azure Machine Learning, GCP Vertex AI, AWS SageMaker). • Develop, optimize, and evaluate LLM-based applications, including RAG (Retrieval-Augmented Generation) systems, leveraging vector stores and prompt orchestration. • Collaborate with Data Engineers and BI teams to ensure access to high-quality, well-structured data for model training and inference. • Apply advanced statistical analysis, experimentation (A/B testing, causal inference), and modeling techniques to solve complex business problems. • Contribute to defining AI roadmaps, ensuring solutions align with business objectives, and driving measurable impact (e.g., cost reduction, performance optimization). • Ensure adherence to AI governance, security, and data compliance standards within regulated environments. • Research and evaluate new AI frameworks (e.g., LangChain, CrewAI) and technologies (e.g., multi-modal AI, agentic workflows). Requirements: • Minimum 4+ years of experience in Data Science or a similar role, with at least 1+ year of hands-on experience in Generative AI/LLMs. • Strong programming proficiency in Python (including libraries like PyTorch, TensorFlow, or scikit-learn). • Hands-on experience with one or more major cloud AI platforms: Azure OpenAI, GCP Vertex AI, or AWS Bedrock/SageMaker. • Deep understanding of LLMs, embeddings, vector databases, and RAG architectures. • Proficiency in SQL and experience working with large, complex datasets in cloud environments. • Solid foundation in statistics, probability, and experimental design (A/B testing). • Familiarity with containerization (Docker) and orchestration (Kubernetes/MLOps tools) for deploying models at scale. • Excellent communication skills in English (minimum B2 level) and the ability to effectively collaborate with technical and business stakeholders. Nice to Have: • Experience with multi-agent systems, behavior trees, or reinforcement learning. • Background in regulated industries (e.g., finance, insurance, healthcare). • Experience with Databricks or Apache Spark ecosystem. What We Offer: • Salary: 16 000 - 23 000 PLN (B2B contract) • Co-financing for training and certifications, as well as guaranteed time for learning during working hours • Private medical care and a Multisport card • Language classes (English) • Flexible working hours and the possibility of hybrid work (Warsaw) • Team integration meetings and company events • Employee referral program with a bonus • An individually tailored career development path
