<h2><strong>About Decathlon</strong></h2>

<p>Decathlon aims to become the best sports digital platform and open ecosystem in the world. We want to enable customers to experience Decathlon through many local sport-centric experiences by connecting many third-party actors and services, in a secure and performant way.</p>

<p>Our digital teams in Lille, Paris (and more…) which bring together more than 5000 collaborators are united to build and scale digital products with the aim to always deliver the best value to our users. With a presence in more than 70 countries, Decathlon is committed to innovation, sustainability, and customer satisfaction.</p>

<h3><strong>Job Description</strong></h3>

<p>Our PRISM (Supply Chain) is looking for an AI Engineer based in Paris. As an AI Engineer dedicated to agent deployment, you will be at the heart of a tight-knit technical team. Your will play a critical role in the industrialization, deployment and monitoring of our Agent capabilities. You will closely work with digital teams (Data, Product, Engineering) to architect the deployment infrastructure, design intelligence routing, and build secure infrastructure allowing our agents to interact natively with our corporate data and legacy systems.</p>

<h3><strong>Responsibilities</strong></h3>

<ul>

<li>Design and deploy solid foundations that will allow our AI agents to be hosted, run, and interact smoothly with our systems during production release.</li>

<li>Design robust pipelines enabling multi-step asynchronous agentic execution (e.g., transactional ingestion and writing flows), by implementing distributed resilience patterns.</li>

<li>Integrate agentic orchestration SDKs (notably Google Vertex AI Agent SDK / ADK), bypassing "black box" limitations of managed frameworks.</li>

<li>Efficiently orchestrate agents in production while ensuring proper information processing, routing to the most suitable models, and guaranteeing optimal cost and token usage management. Also ensure quality and speed of task execution.</li>

<li>Strictly define the scope of action for each agent. You guarantee they only access data and actions for which they are formally authorized, respecting our confidentiality rules, while ensuring data security.</li>

<li>Build advanced performance measurement and tracking pipelines to trace agent reflections and decisions from end to end in order to debug logic in production.</li>

<li>Work with the team to define relevant and consistent data evaluation metrics relative to the defined functional specificities and metrics.</li>

</ul>

<h3><strong>Hard Skills</strong></h3>

<ul>

<li>Robust backend design (Python), operational mastery of containerization (Docker, Kubernetes) and pipelines (CI/CD, automated testing, observability, log management) to ensure robust production releases.</li>

<li>Production-focused Python expertise, mastery of deployment platforms (Vertex AI Agent Builder, Gemini Enterprise Agent Platform) and client/server integration protocols like the Model Context Protocol (MCP).</li>

<li>Experience optimizing context windows for massive frontier models. Request routing to models suitable for the selected solutions.</li>

<li>Ability to build test frameworks for LLMs (LLM-as-a-Judge, Golden Datasets), mastery of deterministic metrics and strict validation of output formats (JSON schema enforcement).</li>

<li>Practical experience with Agentic RAG, <em>Semantic Caching</em> to reduce latency and API costs, or using prompt optimization frameworks (e.g., DSPy)</li>

</ul>

<ul>

<li>Applied experience in supply chain, retail technology, or model deployment via Databricks / MLFlow</li>

</ul>

<h3><strong>Soft Skills</strong></h3>

<ul>

<li>Excellent communication and collaboration skills.</li>

<li>Ability to work effectively in a dynamic and fast-paced environment.</li>

<li>Strong problem-solving skills and attention to detail.</li>

<li>Adaptability and willingness to learn new technologies and methodologies and share them.</li>

<li>Ability to translate complex technical concepts into understandable terms for non-technical stakeholders.</li>

<li>Ability to understand user challenges and associated needs.</li>

</ul>

<h3><strong>Qualifications</strong></h3>

<ul>

<li>Senior Profile: You have solid experience (Machine Learning Engineering) with a strong focus on production infrastructure release.</li>

<li>Ability to leverage managed solutions (Vertex AI) while knowing how to "dive into code" to debug distributed architectures, develop custom connectors, and bypass framework limitations.</li>

<li>Demonstrated ability to evolve in shifting technical environments.</li>

<li>Operational skills on GCP and understanding of containerized environments (Docker, Kubernetes) to autonomously deploy the Agentic layer.</li>

</ul>
