## Description

At Featurespace, part of Visa, we build technology that helps financial institutions protect their customers from fraud and financial crime.

We're looking for a Data Scientist to join our team, developing and managing the analytical capabilities at the heart of our fraud and risk prevention products.

This isn't a role where you build a model and hand it over. You'll work across the full lifecycle of analytical products, from understanding customer problems and exploring data through to developing, deploying, monitoring and improving models in production.

You'll combine strong data science with product thinking and operational ownership. You'll see how your models perform with real customer data, understand the value they deliver, and help ensure they remain effective and well-managed as data, customer needs and fraud patterns change.

Responsibilities:

- Develop ML models using rich and complex transactional datasets.

- Work with customers, product managers, engineers and delivery teams to turn real-world problems into effective fraud and risk prevention products.

- Take models from discovery and experimentation through to production.

- Monitor deployed models, investigate changes in performance and identify opportunities for improvement.

- Retrain, enhance and safely release models as data, customer needs and fraud patterns evolve.

- Measure and communicate the impact of our fraud and risk prevention products.

- Contribute to model governance, documentation and robust production processes.

- Share knowledge, mentor colleagues and help improve how the team works.

Qualifications:

- Experience implementing machine-learning models or analytical algorithms in software.

- Experience using Python, Java or another major programming language for data analysis or machine learning.

- Experience using SQL to analyse data.

- Practical experience working with large, diverse datasets.

- Strong analytical and problem-solving skills, particularly for data-centric problems.

- The ability to pick up new technologies and concepts quickly.

- Experience collaborating with multiple stakeholders on technical projects.

- Clear and concise written and verbal communication.

- The ability to manage and prioritise your own work.

- A degree in a scientific or numerate discipline, or equivalent professional experience.
