Job description

AIT Labs is seeking a Senior Agent Engineer to join a high-impact initiative delivering advanced AI agent and orchestration frameworks for one of the world’s leading consulting organizations, supporting a major transformation project for a prominent Dutch insurance company.

This role is hands-on, highly collaborative, and spans four parallel squads working at the forefront of autonomous agent design, LLM integration, and multi-agent system orchestration at enterprise scale.

What You’ll Do

• Architect, design, and develop robust production-grade autonomous agents and orchestration frameworks (using platforms such as LangChain, AutoGen, and CrewAI).

• Lead and guide technical implementation across four squads to ensure standardized, reusable agent architectures.

• Integrate Large Language Models (LLMs) with external APIs, proprietary toolkits, and various data sources to enable dynamic tool-calling and cross-system workflows.

• Optimize prompt engineering techniques, context window management, and long-running agent workflow stability and state handling.

• Develop monitoring, logging, and evaluation tools to trace agent decision-making and LLM outputs for auditability and performance tracking.

• Collaborate closely with cross-functional squads, sharing knowledge and setting technical direction while ensuring delivery excellence.

• Leverage public cloud platforms (preferably AWS) to design, deploy, and scale AI solutions securely and efficiently.

What We’re Looking For

• 5+ years of relevant software engineering or AI/ML experience, with a focus on agentic architectures, LLMs, or comparable distributed systems.

• Demonstrated expertise in designing and deploying AI-powered solutions within production environments, especially at enterprise or consulting scale.

• Hands-on experience with AI agent orchestration frameworks such as LangChain, AutoGen, or CrewAI (or deep expertise with distributed/cloud systems if the above are new).

• Strong skills in integrating LLMs (OpenAI, Anthropic, open-source) with APIs, databases, and functional toolkits.

• Proficiency in prompt engineering, context management, and addressing the unique stability and scaling challenges of large agentic systems.

• Experience deploying solutions on public cloud (AWS experience strongly preferred).

• Strong documentation, evaluation, and monitoring capabilities for AI systems.

• Excellent communication and collaboration skills; ability to lead and mentor multiple squads, ensuring high engineering standards.

• Candidate must be located in an EU member country

• Fluent English required.

Working Conditions

• Full-time, 40h/week

• 12-month contractor engagement with the possibility of extension

• Contract or B2B arrangement
