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.

Key Responsibilities

1. Application Development & Modernization

• 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.

1. Generative & Agentic AI Integration

• Build solutions leveraging models such as OpenAI, Azure OpenAI, Anthropic, or open-source LLMs.

• Design and implement agentic systems orchestrating multiple tools, actions, or reasoning steps.

• Develop RAG pipelines (indexing, vectorization, retrieval) and advanced contextualization mechanisms.

• Implement guardrails, robust prompting, security policies, and quality control mechanisms.

1. 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: CI/CD, containerization, observability, continuous model evaluation.

1. Collaboration & Technical Leadership

• Work closely with architects, analysts, and business teams to understand use cases.

• Contribute to technical workshops, demos, and proofs of concept.

• Provide advanced technical support to development teams integrating AI.

• Document solutions, patterns, and recommended practices.

1. Innovation & Technology Watch

• 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.

• Identify optimization and innovation opportunities within the application ecosystem.

Technical Skills
Generative AI & Agents

• Strong knowledge of LLMs and frameworks (OpenAI, Azure OpenAI, HuggingFace, Llama, etc.).

• Experience with agentic frameworks: LangChain, OpenAI Agents, Semantic Kernel, AutoGen, CrewAI.

• Expertise in RAG pipelines, embeddings, vector stores, hybrid search.

• Prompt engineering, hallucination mitigation, guardrails.

Development & Application Integration

• Excellent knowledge of Python (mandatory) and ideally another language (C#, Java, TypeScript).

• Mastery of REST/GraphQL APIs, microservices, cloud integration.

• Experience with application modernization (refactor, decoupling, APIfication).

• Good understanding of cloud architectures (Azure, AWS, or GCP).

DevOps / MLOps / GenAIOps

• Containerization (Docker), orchestration (Kubernetes).

• CI/CD pipelines.

• Familiarity with MLOps tools (MLflow, Vertex AI, Azure ML) — a plus.

• Observability, model evaluation, and monitoring.

Soft Skills

• Strong autonomy, initiative, and ability to solve complex problems.

• Technological curiosity and willingness to stay ahead of trends.

• Ability to explain AI concepts to developers and stakeholders.

• Rigor, attention to detail, and quality-driven mindset.

• Collaborative spirit and clear communication.

Profile

• 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.
