Job description

Svitla Systems Inc. is looking for a Principal AI Engineer for a full-time position (40 hours per week) in Europe.  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 our welcoming office.

  • Bonuses for article writing, public talks, and other activities.

  • Generous time off, including vacation, national holidays, sick leaves, and family days.

  • Personalized learning programs tailored to your interests and skill development.

  • Free tech webinars and meetups organized by Svitla.

  • Regular corporate online activities.

  • Awesome team and a friendly, supportive community!
