DEVELOPPEUR EXPERT C# (H/F)
Expert Developer – Application Modernization & Generative AI
The Expert Developer – Application Modernization & Generative AI is responsible for designing, developing, and integrating generative AI solutions and agentic architectures into enterprise systems. This role plays a key part in modernizing existing applications by enriching them with intelligent capabilities (LLMs, RAG, AI agents, copilots) to enhance efficiency, automation, and user experience.
The expert serves as a technical reference, contributes to solution engineering, and ensures rigorous execution aligned with IT standards.
Design and develop generative AI-powered features within existing applications (intelligent assistants, content processing, automated resolution, etc.).
- Refactor and modernize components to enable seamless integration of LLMs and AI agents.
- Implement APIs, microservices, and AI integration modules within existing IT architectures.
- Collaborate with architects to translate technical requirements into scalable, industrializable solutions.
Generative & Agentic AI Integration
- Develop RAG pipelines (indexing, vectorization, retrieval) and advanced contextualization mechanisms.
- Implement guardrails, robust prompting, security policies, and quality control mechanisms.
Engineering, Quality & Performance
- Produce maintainable, tested, high-performance code aligned with industry standards.
- Conduct technical code reviews, propose improvements, and solve complex engineering challenges.
- Diagnose, optimize, and monitor the performance of AI solutions in production.
- Contribute to DevOps/MLOps/GenAIOps practices: Collaboration & Technical Leadership
- Contribute to technical workshops, demos, and proofs of concept.
- Provide advanced technical support to development teams integrating AI.
- Stay up to date with advancements in generative AI, agentic architectures, RAG, and orchestration frameworks.
- Experiment with new models, tools, and techniques to assess enterprise applicability.
- Technical Skills
Generative AI & Agents
- Expertise in RAG pipelines, embeddings, vector stores, hybrid search.
- Excellent knowledge of Python (mandatory) and ideally another language (C#, Java, TypeScript).
- Good understanding of cloud architectures (Azure, AWS, or GCP).
DevOps / MLOps / GenAIOps
- CI/CD pipelines.
- Familiarity with MLOps tools (MLflow, Vertex AI, Azure ML) — a plus.
- Observability, model evaluation, and monitoring.
Ability to explain AI concepts to developers and stakeholders.
- Rigor, attention to detail, and quality-driven mindset.
- 5–10 years of experience in software development.
- Experience with generative AI, LLMs, or intelligent systems (or proven project-based experience).
- Practical experience integrating AI into existing applications or services.
- Contributions to PoCs, pilots, or AI production projects.
