Ciklum is looking for an Expert Python Engineer to join our team full-time in Poland.
We are a custom product engineering company that supports both multinational organizations and scaling startups to solve their most complex business challenges. With a global team of over 4,000 highly skilled developers, consultants, analysts and product owners, we engineer technology that redefines industries and shapes the way people live.
About the role:
As an Expert Python Engineer, become a part of a cross-functional development team engineering experiences of tomorrow.
Position Overview:
- Act as the primary architectural authority for the AS Copilot RAG pipeline upgrade
- Lead the overall strategy for tuning re-rankers, grounding, and citation efforts, while providing high-level supervision to the engineering team
- Design the overarching architecture for custom "Code-RAG" development, specifically focusing on AST-aware semantic chunking for industrial automation code
- Ensure all AI components are architected to be delivered securely as Python source code directly into the client’s Azure DevOps environment
Responsibilities:
- Pipeline Strategy & Evaluation: Oversee comprehensive RAG pipeline audits, establish critical baseline KPIs, and dictate robust evaluation frameworks using tools like RAGAS
- Advanced Retrieval Architecture: Define the approach to tune cross-encoder rerankers on Azure ML and design the architecture for multi-turn grounding and claim-level citation frameworks
- Code-RAG Leadership: Architect custom tokenization and semantic chunking strategies for IEC 61131-3 structured text, avoiding generic tokenizers that destroy function block semantics
- Engineering Oversight: Ensure the delivery of clean, production-grade Python code, oversee architectural code reviews, and provide high-level technical direction to senior and mid-level implementation engineers
- Client Collaboration: Work directly within the client's SAFe cadence, driving joint architectural decisions and ensuring continuous knowledge transfer
Requirements:
- Background: Strong background in Computer Science, Machine Learning, Data Science, or a related technical field at an architectural level
- AI/NLP Expertise: Deep, practical experience and architectural mastery over Large Language Models (LLMs) and advanced Retrieval-Augmented Generation (RAG) architectures
- Technical Stack: Highly proficient in Python. Expert-level experience designing systems with PostgreSQL, pgvector, and hybrid search strategies (BM25 + dense) is required
- Cloud & MLOps: Hands-on, architectural-level experience with the Azure ecosystem, specifically Azure OpenAI, Azure Machine Learning, and Azure DevOps
- Evaluation Frameworks: Deep familiarity with LLM evaluation methodologies and tools like RAGAS, DeepEval, or custom Python test harnesses
- Code Parsing: Extensive exposure to Abstract Syntax Trees (AST) or custom grammar parsing for code-generation use cases is highly desirable
- Soft Skills: Effective problem-solving mindset, capable of high-level client-facing technical leadership, and comfortable working in an embedded, co-delivery partnership
What’s in it for you?
- Strong community: Work alongside top professionals in a friendly, open-door environment
