Description du poste

To accelerate AI adoption and maximize the efficiency of our internal processes across our engineering teams, we are seeking a # **Senior AI Engineer (all genders welcome) – Developer Productivity & SDLC** to build AI-powered tools and shared capabilities across the software development life cycle (SDLC**).** You combine deep expertise in large language models (LLMs), MLOps and agentic AI with the credibility and communication skills to drive change across a distributed engineering organisation spanning multiple technical domains. Rosenxt is a technology group creating innovative solutions for critical infrastructure in harsh environments. Our Software and AI organization spans teams across the world working on everything from data pipelines to autonomous navigation, to customer portals.We are investing in AI-assisted development, shared ML infrastructure, and developer tooling as force multipliers for our engineering teams. This role will build and maintain those shared capabilities, the platforms, standards, and tools that let teams across Rosenxt move faster without solving the same problems independently.This is a hands-on technical role, but also suits someone able to earn trust through demonstrated expertise, bring people along through clear communication, and navigate the organisational complexity of rolling out new tools and practices across distributed teams with different tech stacks and priorities.Your first major project will be leading the technical implementation of an AI-assisted development initiative. Tasks may be evaluating and configuring our AI tool stack, building the retrieval and context systems that make those tools useful for our codebase, and instrumenting the metrics that prove the value. # **What you can expect** * Evaluate, configure, and maintain the AI development tool stack (GitHub Copilot, custom agents, local LLMs).* Standardise how AI agents interact and integrate with our internal tools, services, and development workflows with MCP.* Build retrieval-augmented generation systems over Rosenxt's internal documentation.* Define and implement productivity and quality metrics.
