Model and agent development

• Lead algorithm and framework selection, and design retrieval and grounding strategies, prompts and embeddings.
• Design, build and evaluate agentic workfl ows using frameworks such as Microsoft Agent Framework.
• Evaluate models and LLM-based systems using agreed metrics and methods, including golden datasets, LLM-as-judge evaluation, and tracing and observability tooling.
• Partner with data science colleagues, who own modelling and evaluation

Innovation and growth

• Assess emerging techniques and paradigms and set direction on their practical adoption.

You will have:

• 5+ years’ experience in software or machine learning engineering.
• Substantial experience (typically 2+ years) building and operating LLM-based or agentic systems in production.
• Strong Python skills and knowledge of ML libraries (PyTorch, TensorFlow, scikit-learn).
• Experience with agent and LLM frameworks (e.g. Microsoft Agent Framework, LangGraph) and prompt engineering.
• Strong MLOps experience: CI/CD, container orchestration and infrastructure-as-code, with cloud platforms (Azure preferred).
• Knowledge of NoSQL/document databases (e.g. Azure Cosmos DB) and vector search (e.g. Azure AI Search), plus a solid grounding in relational/SQL database design and querying.
• Experience leading technical decisions, mentoring engineers and reviewing designs and code.
• A strong understanding of data privacy, security and responsible AI, and the ability to explain complex ideas to non-specialists.

Desirable

• Experience with Google’s agent platform (Gemini Enterprise Agent Platform/Vertex AI, including the Agent Development Kit).
• Familiarity with agent interoperability standards such as the Model Context Protocol (MCP) and Agent2Agent (A2A).
• Additional programming languages such as C# and the .NET framework.
• Experience with education-specific standards such as xAPI, LTI or LMS plug-ins.
