Qantev SAS; Paris; Sur place; EUR 120 000 - 180 000; Plein temps

Résumé du poste

Qantev SAS in Paris seeks an exceptionally talented AI Engineering Lead to spearhead Intelligence, RAG & Context streams, writing core Agentic AI code and mentoring a team to deliver high-accuracy, explainable AI solutions.

You will bridge traditional ML with GenAI architectures for hybrid reasoning and fraud detection, and own production-grade pipelines powering claims data, adjudication, and insights for claims handlers.

Qualifications

• Master's degree or PhD from a top engineering school or university, specialized in Computer Science, AI, or Applied Mathematics.
• 7+ years of hands-on experience in applied AI/ML development, with a proven track record of shipping models to production.
• The GPT Pivot: proven transition from heavy custom model training to Foundation Models orchestration, advanced prompting, and tool use.
• Experience in regulated industries and data privacy is a plus, especially with model explainability.

Responsabilités

• Architect, code, and deploy multi-agent systems and deep learning models for Qantev’s Claims Data Platform. Own the technical delivery of your stream.
• Bridge the Paradigm Shift: combine traditional ML and rule-based approaches with GenAI/Agentic architectures for complex hybrid reasoning and fraud detection.
• R&D Industrialization: ensure AI models are wrapped in high-performance, API-first contracts for seamless product integration.
• Team Mentorship: foster a high-ownership engineering culture; mentor Data Scientists and AI Engineers through code reviews and architectural guidance.
• Evaluation & LLMOps: establish evaluation frameworks; build automated benchmarking pipelines to track drift, cost, latency, and token optimization.

Description du poste

Position Overview

We are seeking an exceptionally talented and highly operational AI engineering Lead to spearhead our Intelligence, RAG & Context stream. You will lead hands-on, by example, write core Agentic AI code, architect production-grade pipelines, and mentor a brilliant team of AI and Data Engineers to deliver high accuracy and explainable AI based solutions.

The ideal candidate has lived through the technological paradigm shift from ML to LLM. You have a deep, foundational background in traditional Machine Learning (training, fine-tuning, statistical assessment) but successfully pivoted your career into LLMs, Advanced RAG, and Agentic AI systems, for the healthcare insurance market. Your mission will be to turn raw cognitive power into concrete, enterprise-grade SaaS features. You will lead the development of AI capabilities that power the claims management process, from data entry and enrichment to FWA (Fraud, Waste, and Abuse) and adjudication, providing claims handlers with relevant, accurate insights to accelerate decision-making.

Key Missions & Responsibilities

• Operational & Architectural Leadership: Architect, code, and deploy multi-agent systems and deep learning models for Qantev’s Claims Data Platform. You own the technical delivery of your stream.

• Bridge the Paradigm Shift: Apply your dual expertise to combine traditional ML (for deterministic tasks like OCR/ICR parsing) and rule based (system expert) with GenAI/Agentic architectures (LangGraph, SmolAgents, MCP) for complex hybrid reasoning and fraud detection.

• R&D Industrialization: Ensure that all AI models are wrapped in strict, high-performance, business oriented, API-first contracts that allow seamless integration with our product dev team.

• Team Mentorship: Foster a high-ownership engineering culture. Mentor and develop Data Scientists, AI Engineers, and Back-End Data Engineers through code reviews, pairing, and architectural guidance.

• Evaluation & LLMOps: Establish rigorous evaluation frameworks. Build automated benchmarking pipelines to track model drift, cost-efficiency, latency, and token optimization before any production release.

Qualifications

Education: Master’s degree or PhD from a Top-Tier Engineering School or top University, specialized in Computer Science, AI, or Applied Mathematics.

Experience: 7+ years of hands-on experience in applied AI/ML development, with a proven track record of shipping models to production.

The GPT Pivot: Clear evidence of having successfully navigated the GPT pivot moving from heavy custom model training/feature engineering to mastering Foundation Models orchestration, advanced prompting, and tool use.

Healthcare or Regulated Industry: Experience in regulated industries is a plus, particularly with model explainability, data privacy, and the secure handling of sensitive data.

Technical Stack Expertise: Deep mastery of LLMs, Python, and large-scale data processing pipelines.

Hands-on experience: with modern agentic frameworks (e.g., LangGraph, SmolAgents, Swarm) and the Model Context Protocol (MCP).

LLMOps: Solid foundation in LLMOps tooling (e.g., MLflow, Langfuse, Langsmith) for tracing, scoring, and benchmarking autonomous agents.

Knowledge: Strong understanding of vector databases, advanced RAG patterns, and knowledge graphs.

Soft Skills & Mindset

Product-Minded & Business-Driven: You care about the user impact and the business value of your algorithms, and provide a great production accuracy score.

High Ownership: You thrive in lean, high-performing environments. You prefer moving fast with a small team of A-players.

Communication: Exceptional ability to translate complex probabilistic behaviors into clear, structured insights for non-technical stakeholders (Product, Sales, Clients).
