Full-time Posted about 1 month ago

Role overview

We’re looking for a hands-on Machine Learning Engineer with strong experience building and deploying real-world AI systems. This role focuses on designing scalable ML and LLM-powered solutions for processing large volumes of unstructured data and turning them into structured, actionable insights.

You’ll work at the intersection of machine learning, LLMs and data pipelines – owning systems end-to-end, from experimentation to production.

Responsibilities

  • check_circle Design and build scalable ML/LLM pipelines for processing large-scale document and text data
  • check_circle Develop and optimize LLM-based extraction workflows (classification, entity extraction, summarization, linking)
  • check_circle Integrate LLMs into production systems, including prompt design, evaluation, and orchestration
  • check_circle Work with structured and unstructured data, ensuring data quality and consistency across pipelines
  • check_circle Implement entity resolution and data linking logic across multiple data sources
  • check_circle Collaborate on building knowledge-oriented systems (e.g. search, semantic layers, or lightweight graph structures)
  • check_circle Optimize models and pipelines for performance, cost, and reliability in production environments
  • check_circle Contribute to system design, including scalability, fault tolerance, and maintainability
  • check_circle Work closely with cross-functional teams to deliver and iterate on AI-driven features

Basic qualifications

  • 5+ years of experience in Machine Learning, Applied AI, or Data Engineering
  • Strong Python skills and experience with ML/LLM ecosystems
  • Hands-on experience deploying ML or LLM systems to production
  • Experience with data processing frameworks (e.g. Spark, Beam, or similar)
  • Solid understanding of ML fundamentals and NLP concepts
  • Experience working with large datasets and building data pipelines
  • Familiarity with LLM frameworks and tools (e.g. LangChain, LlamaIndex, or similar)
  • Experience with SQL and data modeling
  • Understanding of system design and scalable architectures
  • Experience with Docker and cloud platforms (AWS, GCP, or Azure)

Preferred qualifications

  • Experience with knowledge graphs or graph databases
  • Experience building evaluation frameworks for LLM outputs
  • Familiarity with vector databases and semantic search
  • Experience working with on-prem or privacy-sensitive environments
  • Exposure to backend development (e.g. APIs, microservices)
  • Strong ownership mindset and ability to work independently
  • Pragmatic approach to building production-ready AI systems
  • Ability to balance experimentation with delivery
  • Comfortable working in fast-moving, ambiguous environments
  • Real-world AI systems (not just PoCs)
  • High ownership and impact
  • Modern ML + LLM stack
  • Opportunity to shape scalable AI solutions from the ground up
  • Covered vacation period: 20 business days and 5 days off
  • Free English classes
  • Flexible working schedule
  • Truly friendly and supporting atmosphere
  • Working remotely or in one of our offices
  • Medical insurance for employees from Ukraine
  • Legal support
