Ciklum is looking for an Artificial Intelligence / Machine Learning 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 Artificial Intelligence / Machine Learning Engineer, become a part of a cross-functional development team engineering experiences of tomorrow.
The Legacy Code Semantic Documentation Project is a 26-week enterprise initiative for a global industrial automation leader. The primary objective is to engineer an automated, AI-assisted pipeline to generate structured, system-level Markdown documentation directly from an undocumented ~400K LOC codebase (spanning IEC 61131-3 languages and ANSI C/C++).
Operating within a dedicated, zero-data-egress secure tenant, the technical architecture combines Tree-sitter AST parsing, Neo4j knowledge graphs, Qdrant vector search, and self-hosted open-weight LLMs (Llama 3.1 / Mixtral family) with NLI-based validation. Delivery is structured across 7 work packages executing over a 6-month period, governed by strict contractual KPIs: ≥95% code coverage, ≥92% NLI-verified factual precision, and ≥90% SME validation acceptance. All outputs align with EU Cyber Resilience Act (EU CRA) requirements for SBOM and source-level traceability.
Responsibilities:
- AI Pipeline Development: Implement and maintain multi-pass LLM generation workflows using self-hosted open-weight models (Llama 3.1, Mixtral)
- RAG Retrieval Integration: Connect vector search routines (Qdrant) and graph queries (Neo4j) into unified prompt context builders
- Evaluation Pipeline Support: Integrate automated NLI checking scripts to filter low-confidence generations and verify factual precision
- Prompt Engineering & Templating: Construct, benchmark, and refine domain-specific prompts to output structured Markdown assets
- Cross-Functional Collaboration: Partner with Data Engineers on schema ingestion and work with QA to validate AI-generated output quality against code baselines
Requirements:
- Professional Experience: 3+ years in commercial software development or data science, with 1.5+ years building and deploying practical LLM/AI applications
- Core Technical Stack: High proficiency in Python, clean code principles, REST APIs, and asynchronous programming
- Practical AI/RAG Exposure: Demonstrated working knowledge of RAG architectures, prompt design, and vector databases (Qdrant/OpenSearch)
- Model Execution Understanding: Familiarity with self-hosted open-weight LLM workflows, token management, and inference engines (vLLM, TGI)
- Engineering Best Practices: Hands-on experience with Git, Docker containerization, unit testing, and CI/CD pipelines
- Language: Professional proficiency in English (B2+/C1)
What’s in it for you?
- Strong community: Work alongside top professionals in a friendly, open-door environment
- Growth focus: Take on large-scale projects with a global impact and expand your expertise
- Tailored learning: Boost your skills with internal events (meetups, conferences, workshops), Udemy access, language courses, and company-paid certifications
- Endless opportunities: Explore diverse domains through internal mobility, finding the best fit to gain hands-on experience with cutting-edge technologies
