• Hands-on experience developing applications or services using Generative AI and Large Language Models.
• Good understanding of LLM concepts such as prompting, context management, tokens and model limitations.
• Experience integrating services and systems through REST APIs.
• Experience working with relational databases and data-driven applications.
• Good understanding of software architecture and application integration.
• Ability to investigate complex technical problems and propose pragmatic solutions.
• Ability to work autonomously and take ownership of technical topics.
• Good communication and collaboration skills in an international environment.
• Professional working proficiency in English. Nice to have The following skills are valuable but are not mandatory:
• Experience with Microsoft Azure AI Foundry or similar enterprise AI platforms.
• Experience with Retrieval-Augmented Generation (RAG) architectures.
• Knowledge of embeddings, vector databases and semantic search.
• Experience with AI orchestration frameworks such as Microsoft Semantic Kernel or equivalent technologies.
• Experience working with both C#/.
NET and Python in professional projects.
• Experience with ASP.
NET Core and enterprise web applications.
• Experience integrating AI solutions with enterprise data sources or business systems.




• Experience with AI evaluation, observability or usage and cost monitoring.
• Knowledge of locally deployed or open-source LLMs.
• Experience with multimodal AI, document processing, Vision models or OCR.
• Experience using AI-assisted development tools. What we are looking for We are looking for an experienced engineer who combines strong software development skills with practical Generative AI experience. The ideal candidate should be able not only to experiment with an LLM, but also to transform an AI concept into a maintainable application that can interact with existing systems and enterprise data. We value technical curiosity and pragmatism. The AI ecosystem evolves quickly, so the ability to evaluate new technologies, understand their strengths and limitations, and select the right approach for a given problem is more important than expertise in any single framework. We are also looking for someone who can bring experience to the team: an engineer capable of working independently, contributing to technical decisions and helping less experienced team members develop their AI engineering skills.
