What You'll Do

  • Apply theoretical NLP and LLM knowledge to design advanced language understanding components;
  • Design and develop robust AI pipelines for key conversational analytics features;
  • Optimize ML models and inference pipelines for performance and cost-efficiency;
  • Research and integrate state-of-the-art LLM architectures (e.g., BERT, T5, GPT) and methodologies (prompt engineering, embeddings, zero-/few-shot learning);
  • Collaborate on the architecture and deployment of AI components using Docker and Azure services;
  • Maintain and monitor AI systems;
  • Contribute to continuous improvement of model accuracy, latency, and explainability;
  • Participate in code reviews, documentation, and team knowledge sharing;

The global benefits package includes: * Technical and non-technical training for professional and personal growth; * Internal conferences and meetups to learn from industry experts; * Support and mentorship from an experienced employee to help you professional grow and development; * Internal startup incubator; * Health insurance; * English courses; * Sports activities to promote a healthy lifestyle; * Flexible work options, including remote and hybrid opportunities; * Referral program for bringing in new talent; * Work anniversary program and additional vacation days.
