Key Responsibilities

Agentic AI Design & Development

  • Design and implement autonomous AI agents capable of reasoning, planning, and executing goal-driven actions with minimal human intervention
  • Develop multi-step workflows combining LLM reasoning, tool use, and structured decision-making
  • Build and maintain prompt engineering strategies, including chain-of-thought, role-based prompting, and instruction design
  • Implement memory architectures (short-term and long-term) for context-aware agent interactions
  • Develop evaluation frameworks to measure agent performance, accuracy, and reliability

Platform Integration & RAG Systems

  • Build retrieval-augmented generation (RAG) pipelines connecting agents to organisational knowledge bases and document repositories
  • Integrate agents with internal APIs, data sources, and enterprise systems
  • Design and optimise vector search strategies using embedding models and vector databases
  • Implement document processing pipelines (ingestion, chunking, indexing, retrieval)
  • Develop connectors for heterogeneous data sources (structured databases, unstructured documents, web content)

Multi-Agent Orchestration

  • Design multi-agent architectures where specialized agents collaborate to accomplish complex tasks
  • Implement agent coordination patterns (sequential, parallel, hierarchical, event-driven)
  • Build routing and delegation logic for directing user requests to appropriate specialized agents
  • Define inter-agent communication protocols and shared state management
  • Optimise agent workflows for latency, cost, and quality trade-offs

Managed Agentic Platforms

  • Leverage managed agentic services such as AWS Bedrock AgentCore and Microsoft Foundry Agent Service
  • Evaluate and recommend platform capabilities for specific use cases (tool integration, knowledge bases, guardrails)
  • Design hybrid architectures combining managed services with custom agent implementations
  • Stay current with evolving managed platform features and incorporate relevant capabilities

Safety, Governance & Monitoring

  • Implement content safety guardrails, input/output filtering, and policy enforcement
  • Design human-in-the-loop approval mechanisms for sensitive or high-impact agent actions
  • Build observability pipelines: trace agent decisions, log tool calls, monitor performance
  • Define and track evaluation metrics for agent quality and safety
  • Contribute to data protection impact assessments when introducing new AI capabilities
  • Ensure compliance with GDPR, data residency requirements, and institutional policies

Research Unit & Corporate Service Support

  • Engage with research units and corporate services to identify workflows suitable for AI agent automation
  • Translate domain-specific requirements into agent specifications and implementation plans
  • Conduct discovery workshops and prototype demonstrations to validate agent approaches
  • Provide technical guidance and training to users adopting AI agent capabilities
  • Document agent capabilities, limitations, and best practices for end users


Required Skills & Experience

Technical Expertise

  • Strong proficiency in Python and async programming patterns
  • Demonstrated experience building and deploying LLM-based agents in production environments
  • Hands-on experience with agent orchestration frameworks (LangChain, LangGraph, CrewAI, Strands Agents, or equivalent)
  • Solid understanding of RAG architectures: embeddings, vector databases, chunking strategies, reranking
  • Experience with managed AI services on AWS (Bedrock incl. AgentCore) and/or Microsoft (Foundry incl. Agent Service)
  • Understanding of LLM capabilities and limitations across model families
  • Experience with API design, REST/GraphQL, and integration patterns
  • Familiarity with containerised deployments and Infrastructure as Code
  • Knowledge of observability tools and practices (logging, tracing, metrics)

Proven Track Record (in lieu of years of experience)

  • Portfolio of shipped agent systems: production deployments, open-source projects, or documented enterprise implementations
  • Demonstrated ability to take an agent from concept through design, development, and production deployment
  • Evidence of solving real-world problems with agentic AI (GitHub repositories, case studies, technical blog posts, or conference presentations)
  • Experience working autonomously on complex technical problems with minimal supervision


Nice to Have

  • Experience with multi-cloud environments (AWS + Azure)
  • Familiarity with Open WebUI, LiteLLM, or similar open-source AI platforms
  • Understanding of European data protection regulations (GDPR)
  • Contributions to open-source AI/ML projects


Certifications (Preferred, not required)

  • AWS Certified Generative AI Developer - Professional
  • Azure AI Engineer Associate
  • Any relevant specialisation in generative AI or agentic systems


Soft Skills

  • Strong problem-solving mindset with ability to navigate ambiguity
  • Effective communication with both technical and non-technical stakeholders
  • Ability to work autonomously and manage priorities in a fast-evolving field
  • Collaborative approach to supporting diverse teams (researchers, engineers, corporate staff)
  • Curiosity-driven: proactive in exploring new tools, frameworks, and approaches
  • Fluency in French and English
