Svitla Systems Inc. is looking for a Principal AI Engineer for a full-time position (40 hours per week) in Ukraine. Our client is a middle-market private equity firm that gathers information and reports to enhance environmental and social impacts on the customer’s business.
We are seeking a visionary Principal AI Engineer to lead the development of the AI Platform. As a founding member of the AI Center of Excellence, you will lead by example to build a high-performance team. You will build sophisticated Agentic Systems and Adaptive RAG engines that conduct autonomous research to solve complex, real-world problems. You will be a key member of defining "how we do AI, setting the standards for engineering quality, security, and innovation.
Tech Stack: * Languages: Python, TypeScript; * AI Frameworks: LangChain/LangGraph, Pydantic AI, Databricks Mosaic AI; * Models: Azure OpenAI, Open Source LLMs (Llama 3, Mistral, etc.) * Infrastructure: Microsoft Foundry, Azure AI Search, Azure Container Apps, Delta Lake, Vector; * Databases like Databricks Vector Search.
Requirements * 10+ years of experience in software engineering, with a strong focus on building data-intensive, distributed systems. * Significant hands-on experience deploying AI/ML solutions to production. * While deep GenAI experience is preferred, a strong traditional ML Engineering background is a big plus. * Bachelor’s or Master’s degree in Computer Science, Mathematics, Engineering, Physics, or related fields. * Deep understanding of building production RAG systems. Knowledge of the nuances of chunking strategies, hybrid search (dense + sparse), re-ranking, and context management. * Experience in building systems where LLMs use tools, maintain state, and execute multi-step plans. Familiarity with the challenges of loops, recursion, and hallucination mitigation. * You are a software engineer first. You write clean, maintainable Python code and understand distributed systems, API design (FastAPI), and cloud architecture. * You can balance the “bleeding edge” with “boring technology” to deliver pragmatic business value. You understand the trade-offs between cost, speed, and accuracy.
Responsibilities * Design and build scalable, reusable AI services (e.g., the “Adaptive RAG Engine,” “Text-to-SQL Service,” and “Agentic Runtime”) that product teams can easily integrate. * Serve as the technical authority on Generative AI. Mentor senior engineers, conduct code reviews, and drive the adoption of engineering best practices (testing, CI/CD for AI, evaluation). * Lead the development of multi-agent systems capable of complex reasoning, planning, tool use, and self-correction (using frameworks like LangGraph or Semantic Kernel). * Load datasets and knowledge sources from external systems. * Shape and transform data to optimize it for Hybrid or Semantic Search, providing the best possible knowledge context to LLMs. * Move prototypes to production while focusing on latency, cost optimization, and reliability. Implement robust evaluation pipelines (LLM-as-a-Judge) to measure quality and prevent regression. * Implement guardrails for PII protection, hallucination detection, and prompt injection defense. * Partner with product teams to de-risk their AI roadmaps. Translate abstract business requirements into concrete architectural patterns.
We offer * US and EU projects based on advanced technologies. * Competitive compensation based on skills and experience. * Regular performance appraisals to support your growth. * Flexibility in workspace, either remote or in one of our development offices. * Comprehensive medical insurance, including dental and massages. * Personalized learning program tailored to your interests and skill development. * Sport reimbursement program for onsite and online activities. * Bonuses for recommendations of new employees. * Bonuses for article writing, public talks, and other activities. * 20 vacation days, 10 national holidays and 5 sick leaves. * Maternity leave policy and family days off. * Free tech webinars and meetups organized by Svitla. * Welcome and anniversary presents, gifts for children, and more. * Regular corporate events and meetups. * Awesome team, friendly and supportive community!
