Job summary

Pluxee is seeking a GenAI Engineer to own an internal AI platform, build and deploy production-grade AI agents, and collaborate with IT teams across the group. The role blends hands-on platform ownership with GenAI advisory duties for multiple business units.

The candidate should bring 5+ years in backend/full-stack development and 2+ years in GenAI/LLM systems, with cloud deployment experience (Azure preferred). Hybrid work in Paris is offered.

Qualifications

• 5+ years in backend / full-stack development, including at least 2 years on GenAI / LLM systems in a production context.
• Proven experience deploying and operating AI platforms on cloud infrastructure (Azure preferred; AWS or GCP accepted).
• Background in international or multi-BU enterprise environments is a plus.

Responsibilities

• Own the technical roadmap: platform evolution, updates, and new integrations (MCP connectors, business tools).
• Ensure reliability, security, and performance of the production platform (Kubernetes / Azure, CI/CD, monitoring).
• Design and deploy business AI agents: system prompts, tools, knowledge bases, per-team or per-BU access control.
• Manage the LLM integration layer: model routing, guardrails, token quotas, cost management.
• Drive the architecture toward a multi-tenant platform: agents and knowledge bases scoped per Business Unit.
• Operate existing and new MCP (Model Context Protocol) servers: Atlassian (Jira / Confluence), web search, and upcoming connectors (SharePoint, etc.).
• Define and roll out AIDLC standards: integrating AI into code review, generation, testing, and documentation workflows.
• Support development teams in adopting GenAI tools (code assistants, agents, RAG on codebases).
• Identify priority AI use cases across IT departments and co-build solutions with the teams.
• Act as the GenAI technical reference: architecture, model selection, security, GDPR and EU AI Act compliance.
• Lead technology watch on the GenAI ecosystem and bring forward concrete, actionable proposals.
