AI Systems Engineer: LLMs, RAG & Production ML

BETUNED; Antwerpen; Sur place; EUR 70 000 - 95 000; Plein temps

Résumé du poste

BETUNED is seeking a Mid-Level AI Systems Engineer to bridge AI engineering and MLOps, with hands-on work on LLMs, agents, and RAG pipelines. You’ll design, build, deploy, and operate production-grade AI systems with a focus on generative AI, LLM-based apps, and reliable ML operations.

The role sits at the intersection of engineering and operations, collaborating with the ML team and other delivery units. Expect growth toward a Team Lead position over time, and a split of 60-70% AI Engineering

Responsabilités

• Orchestrate AI system components: LLMs, vector databases, APIs, orchestration layers, and user interfaces
• Develop autonomous agents and conversational systems that can plan actions and interact with external tools or APIs
• Build and optimise RAG pipelines connecting enterprise data sources to LLMs for grounded, contextualised, reliable answers
• Evaluate system quality through generative AI metrics, coherence tests, and production monitoring (latency, API costs, bias)
• Deploy and scale solutions with strong attention to latency, security, reliability and cost efficiency
• Keep an eye on the ecosystem for new models, frameworks and techniques, including open-source tools such as LangChain, LangGraph, Langfuse, etc.
• Perform prompt and context engineering to improve output quality, reduce hallucinations, and manage conversational state effectively
• Build and maintain automation for model deployment, including CI/CD pipelines and automated testing
• Continuously monitor model performance in production, including drift detection and quality metric tracking
• Manage updates of libraries, models, and related dependencies in production environments
• Ensure versioning, reproducibility and safe rollout of models and AI services
• Collaborate closely with ML engineers, developers, DevOps and infrastructure teams for smooth delivery
• Stay current with the latest MLOps practices, tools and platform components
