About the role

By combining software engineering and data analysis, machine learning engineers enable machines to learn without the need for further programming. The purpose of this role is threefold split across our AWS (Sagemaker) and SAS platforms:

1) To build a viable machine learning and AI platform in support of allow the business to adopt machine learning products.

2) Build viable machine learning data products and support wider business teams building machine learning data products, so that the business continues to build beyond project inception - ensuring development is targeted towards sustainable deployment and growth.

3) To build re-usable frameworks to leverage the technology stack to its best abilities (i.e. optimisations for Teradata specific functions within machine learning data products)

Scope of Role

Leadership:

• The role works directly with business stakeholders on machine learning products to ensure the development is targeted towards sustainable deployment and growth.
• The role also works directly across a wider engineering and data team to align delivery of machine learning products.
• The role provides thought leadership in analytical teams, processes and platforms (people, systems, process).
• The role has influence in a team of over one hundred data professionals in the use of machine learning across the business, deploying effective communication and relevant training.

Nature and Area of impact:

• The role has influence in a team of over one hundred data professionals in the use of machine learning across the business, deploying effective communication and relevant training.
• Machine Learning has a direct and indirect influence on the way we interact with customers, from customer campaign selection to product recommendation to credit decisioning – machine learning has a positive impact on how we interact with customers.
• Successful machine learning models significantly improve business performance through increases in sales and return and/or reduction in risk.
• Through accurate, robust, ethical, secure, and sustainable machine learning deliveries we ensure that our business and customers are served and protected.
• Part of this role is to ensure the strategic roadmap of machine learning within the retail business is in line with Financial Services development.
• Successful machine learning engineers will develop and grow the use of machine learning within the business in a profitable and sustainable way.

Budget/Financial:

• Successful machine learning engineers will develop and grow the use of machine learning within the business in a profitable and sustainable way.
• Project/Deployment Cost/Benefit – Machine Learning Engineers have the responsibility to ensure the areas in which they commit time have a clear and tangible ‘path to value’ and that the benefit is worth the investment of time, effort, cost and limited resource.
• Direct Spend – The role is responsible for ensuring platform spend is accounted for and in line with budget and expectations.
• Strategic Direction – The role has direct and strategic influence on the ML & AI roadmap which has the potential to divert spend from existing providers to more cost-effective alternatives.

Key Responsibilities.

• Understand and use computer science fundamentals, including data structures, algorithms, computability and complexity and computer architecture.
• Use exceptional mathematical skills, to perform computations and work with the algorithms involved in this type of programming.

• Collaborate with data engineers to build data and model pipelines.
• Manage the infrastructure and data pipelines needed to bring code to production.
• Demonstrate end-to-end understanding of applications (including, but not limited to, the machine learning algorithms) being created.
• Build algorithms based on statistical modelling procedures and build and maintain scalable machine learning solutions in production.
• Use data modelling and evaluation strategy to find patterns and predict unseen instances.
• Apply machine learning algorithms and libraries.
• Communicate and explain complex processes to people who are not programming experts.
• Liaise with stakeholders to analyse business problems, clarify requirements and define the scope of the resolution needed.
• Analyse large, complex datasets to extract insights and decide on the appropriate technique.
• Research and implement best practices to improve the existing machine learning infrastructure and leverage existing platforms.
• Provide support to engineers and product managers in implementing machine learning in the product.
• Liaise with Financial Services to ensure opportunities for alignment on machine learning systems and processes.
