As the team grows, the role will keep changing. We want to hear from applicants who are driven, inquisitive, eager to learn, and open to exploring new work methods. Candidates should have a strong background in large-scale applications and data platforms. 

• Develop and maintain machine learning systems in Python alongside data scientists and other machine learning engineers. 

• Take projects from experimentation through to production, including design and integration with other systems such as continuous integration and continuous delivery tools, application programming interfaces, and Dynatrace. 

• Engage with collaborators across business and technical teams to understand requirements and influence decision-making. 

• Propose, evaluate and advocate for technology, platform and architecture choices in line with Lloyds Banking Group guidelines. 

• Drive excellent engineering standards, consistency and culture across the team through technical leadership and knowledge sharing. 

• Play a leading role in incident management and resolution, working closely with the strategic platform team and business partners. 

• Proactively find opportunities to improve solutions and present clear plans to deliver them. 

• 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. 

What we’re looking for 

• Advanced understanding of software engineering best practice, programming concepts, automated testing, continuous integration and continuous delivery, and production deployments. 

• 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. 

Desirable skills/experience 

• Exposure to generative artificial intelligence and agentic tooling, such as Agent Development Kit or LangChain.
