• Strong Python development experience in a commercial machine learning environment, including libraries such as Pandas, Scikit-Learn and XGBoost.

• Experience working with cloud-based machine learning and data platforms, including technologies such as Vertex AI, BigQuery, Cloud Run or equivalent cloud services.

• Practical experience implementing MLOps tooling and frameworks such as Kubeflow Pipelines, dbt or similar solutions, including monitoring and operationalising large-scale models.

• Experience working with Infrastructure as Code, Kubernetes, API authentication and distributed systems within enterprise environments.

And any experience of these would be great

• Exposure to Generative AI and Agentic AI frameworks such as LangChain, ADK or similar technologies.

• Experience configuring and optimising Large Language Models (LLMs), balancing performance, risk and cost considerations.

• Experience partnering with architecture, platform, governance and risk teams to successfully deploy solutions into production.

• Knowledge of retail banking, lending products or regulated financial services environments.
