AI Agent Systems Research Engineer

European Tech Recruit; Paris; Sur place; EUR 65 000 - 95 000; Plein temps

Résumé du poste

European Tech Recruit is seeking a Research Engineer to help develop intelligent agent-based systems powered by large language models. This role sits at the intersection of applied research and engineering, turning promising ideas into working prototypes and building reliable systems capable of reasoning, using tools, and completing complex tasks.

You will work on designing LLM-powered agents, integrating tools, memory, retrieval, and evaluation to ensure robust performance.

Qualifications

• Hands-on experience with LLM-based agents.
• Strong software engineering and experimental development skills.
• Experience building AI agents, multi-step LLM workflows, or tool-using applications.
• Understanding prompting, retrieval-augmented generation, structured outputs, model evaluation, and orchestration.
• Ability to design controlled experiments and interpret results critically.

Responsabilités

• Research and prototype new approaches for LLM-powered agents.
• Design systems that combine language models with tools, memory, retrieval, planning, and structured workflows.
• Build experiments and evaluation frameworks to measure agent quality, reliability, and performance.
• Investigate challenges such as hallucination, long-horizon task completion, context management, and error recovery.
• Translate research findings into practical, maintainable implementations.
• Analyse experimental results and use them to guide technical decisions.
• Keep pace with relevant developments in language models, agent architectures, and evaluation techniques.
• Share findings clearly through technical documentation, demonstrations, and discussions.
