Job description

As a Machine Learning (ML) Engineer, you'll play a meaningful role in developing, operating and maintaining ML solutions across Consumer Lending. You'll work on different projects with a wide variety of colleagues to understand how we can apply the latest ML thinking to deliver value. Working in our growing team enables you to get close to and understand how the business operates, how we serve our customers and the role that Data Science and ML can play in making things better for LBG and its customers – and it's this proximity to the business that sets us apart. Your role will evolve as the team matures, so we'd love to hear from applicants who are highly motivated, curious, keen to learn and open to trying new ways of working. We're also looking for applicants with a proven background in working with large-scale applications and data platforms.

Key Responsibilities

• Develop and maintain end-to-end ML systems in Python alongside our data scientists, including engineering new features, specifically providing expert ML input.
• Maintain and refine high quality, reusable data and ML pipelines at scale.
• Play a leading role in incident management and resolution, working closely with the strategic platform team and business partners.
• Work collaboratively with others to identify, develop and implement new solutions that deliver customer and business value.
• Promote high quality ML practices alongside maintaining an effective control environment, sharing knowledge with others and offering technical leadership or support as needed.
• Proactively seek opportunities to improve solutions and present concrete plans to deliver these.
• Deliver in line with LBG data science, model governance and risk management policies and procedures, maintaining constructive relationships with specialist colleagues in these areas.
• Grow your capability by pursuing and investing in personal development opportunities.
• Keep up-to-date with emerging developments in the Data Science, ML engineering and MLOps fields, and proactively share findings with the team.

Qualifications

• Computer science fundamentals: a clear understanding of data structures, algorithms, software design, design patterns and core programming concepts.
• Experience with the core Python data stack (Pandas, NumPy, Scikit-learn, etc) developed in a commercial setting, an appreciation of pipeline orchestration frameworks (e.g., Airflow, Kubeflow Pipelines, etc), applied knowledge of statistical modelling and/or experience in implementing and supporting ML systems.
• Demonstrable understanding of key concepts including Python testing frameworks, CI/CD, source control, etc.
• Experience of working with large data sets and with data platforms to deploy scaled Machine Learning models in a live environment.
• Demonstrable commercial experience across the full software development lifecycle, from experimentation through to live production.
• Exposure to some GCP cloud tooling (e.g. VertexAI, BigQuery) is highly desirable.
• Sound understanding of and/or desire to learn about retail banking and how to apply your technical skills in this area.

Working Pattern

Our work style is hybrid, which involves spending at least two days per week, or 40% of your time, at one of the above listed hubs.
