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.

Overlap : 7 pm CET

REQUIREMENTS :

- 10+ years of experience in software engineering, with a robust focus on building data-intensive, distributed systems.
- 8-10+ years of experience in ML engineering.
- Strong background across classic ML, GenAI, and Agentic 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.
- Excellent communication skills in English (clear, concise, to the point).
- High ownership skills with the ability to take the initiative and drive outcomes independently.
- Founding member of the AI CoE, with significant influence over technology choices, frameworks, and engineering standards.
- A STEM degree from a reputable university.

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.
- Well-established remote culture and flexible working hours.
- No trial period.
- Annual performance appraisals.
- Competitive compensation in USD gross based on skills and experience.
- B2B contract with Svitla Systems Inc. (US legal entity).
- 20 vacation days, 10 national holidays, and 5 paid sick leaves.
