• Provide results aligned with data science, model governance, and risk management policies and procedures, sustaining positive connections with specialized colleagues within these domains.

Why join us?

You’ll join a diverse, energising and informal environment focused on equal opportunity and career progression. The role offers the opportunity to work flexibly and collaboratively, while contributing to machine learning solutions that support the Consumer business and its customers.

We take personal and professional development seriously and will support you to make a positive difference to the team and Lloyds Banking Group as a whole.

• Commercial experience using key Python libraries for machine learning, such as Pandas, Scikit-learn and XGBoost.
• Proven development experience with cloud services, data stores and architectures, such as Vertex AI, BigQuery and Cloud Run.
• Hands-on experience with machine learning operations tooling and frameworks used with large datasets, such as Kubeflow Pipelines and dbt, including an understanding of production monitoring.
• Experience with Infrastructure as Code, including Terraform, Kubernetes, application programming interface authentication flows and networking.
• Experience collaborating with central platform, architecture and governance teams to move solutions into live production.
• Experience across the full software development lifecycle, from experimentation through to live production.
• A sound understanding of retail banking, or a desire to learn how to apply your technical skills in this area.
