Reporting to: Head of Data Science

Key Duties & Responsibilities

• Developing industry leading data science solutions through:
• Defining data requirements and extracting required data to support solution development.
• Performing exploratory data analysis to improve understanding of underlying trends and behaviours to help inform feature engineering work and next steps in modelling process.
• Support in the designing and development of scalable and efficient data driven solutions.
• Input into the design decisions determining optimal data science methodologies and technologies to use to solve the problem at hand.
• Ensuring integrity of the data science solutions in terms of the underlying statistical and economic models and assumptions.
• Collaborating with the MLOps team in the development and deployment of proposed solutions to a live environment and tracking the effects in real time.
• Devising statistically robust testing plans to validate effectiveness of solutions.
• Collating results from in-market tests and validating them.
• Effectively communicating outputs of work to other team members and business stakeholders in a manner that can be understood by both technical and non-technical audiences.
• Work with colleagues in Revenue function to ensure they are equipped with required tools, models and resources for optimising trading performance.
• Support the wider business with BAU tasks related to the services Data Science provide or with designing new data-driven solutions to solve their complex business problems.
• Proactively work with wider data & technology teams to support the collection of new data and refinement of existing data sources.
