  • Processing large volumes of textual and multimodal data — cleaning, preparing, and structuring it; Applying prompt engineering techniques to optimize generation quality;
  • Embedding LLMs into business workflows — information retrieval, support automation, code review assistance, and documentation generation;
  • Evaluating model performance — quality metrics, A/B testing, and user feedback loops;
  • Collaborating with Data Scientists and the Platform Team; Writing MCPs (Model Control Policies);
  • Conducting LLM training sessions for employees on both general and internal tools (e.g., via MCP).

What Will Help You Succeed

  • Experience with workflow automation tools (e.g., n8n);
  • Strong knowledge of Python and modern ML/AI frameworks (PyTorch, TensorFlow, JAX);
  • Solid understanding of NLP and LLM architectures;
  • Hands-on experience with RAG frameworks;
  • Proficiency in version control systems (Git);
  • Understanding of MLOps principles; Awareness of information security and safe LLM usage practices.

Nice To Have

  • Basic knowledge of Kubernetes (k8s).

What We Offer

  • No dress code and minimal bureaucracy;
  • Choice between a MacBook or Windows laptop;
  • Health insurance and mobile plan coverage;
  • Free lunches and drinks;
  • Fresh fruits and snacks in the office every day;
  • Free English classes; Fitness reimbursement;
  • Partial coverage (50% gross) for kindergartens and schools.
