Overview:

In the Financial Crime Solutions (FCS) team at Mastercard, we build and deliver products and services powered by payment data to detect and prevent financial crime. We are an award winning team, combining advanced data science with deep payment expertise to help financial institutions combat fraud, scams, and money laundering by uncovering the criminal behaviours that drive them.
We are now building a new Centre of Excellence in Asia-Pacific, designed to act as a regional hub for the Cyber & FCS vertical. The Centre will drive scalable growth and robust delivery tailored to APAC priorities, and strengthen Mastercard’s leadership in anti scam and fraud prevention through thought leadership and industry engagement.

Role
As a Lead Data Scientist, you will be a core contributor to a newly established Centre of Excellence, building and maintaining data science models that help detect fraud, scams, and money laundering using payments data.
In the research discipline you will help build systems that expose money laundering and detect fraud as well as work with the other data scientists and clients to understand the underlying behaviours employed by criminals. You will be product focused, working in close collaboration with the regional team.
A key aspect of this role is building and sustaining local data science capabilities within the Centre of Excellence, ensuring we can effectively support customers across Asia Pacific while remaining closely aligned with global strategy and guidance. This includes acting as regional experts in the development, maintenance, and application of financial crime models, enabling timely, context aware support for our regional clients.

In this position, you will:

• Perform proof-of-concept projects, engage in product design and build prototypes.
• Use the full range of data science based techniques to develop new and novel algorithms to aid existing and new financial crime products.
• Be able to perform novel research to help us and our clients understand the different criminal behaviours in payments data.
• Think about how derived insights can be turned into new products and services we can offer to external clients.
• Be ready to learn new technologies as required and engage with various technology stacks.
• Write white papers, patents, and client facing data visualisations.
• Consider the full impact of your work. This means considering privacy, security, and regulation, as well as the performance of your code and the accuracy of your models.
• Act as a regional expert in building, maintaining, and evolving financial crime models, ensuring they remain effective, well understood, and appropriately governed.
• Support customers across Asia Pacific by providing data science guidance and services, informed by global frameworks while tailored to local market needs and constraints.
• Contribute to and support regional initiatives such as proof of value exercises and targeted solution deployments.
• Collaborate closely with global data science and product teams to align on methodology, research direction, and model strategy, while owning regional execution and contextualisation.
• Enable scalable customer support by strengthening local DS ownership, reducing dependency on global teams for region specific model understanding and application.

Skills Required:

Your passion is focused on the design of algorithms to solve real, pressing problems using data. You will have an interest in the financial services industry and want to tackle financial crime in the wider economy. You are excited by building products for clients and are keen to engage in the design processes this involves. Specifically:

• You can write Python to a high standard and are familiar with the standard data science libraries such as pandas, polars, scikit-learn and networkx.
• You are capable of developing new algorithms in novel situations and can demonstrate previous work to evidence this.
• You are keen to understand the data we work with and have a keen interest in how to model the behaviours it exposes.
• You are able to communicate with non-tech colleagues about technical matters, and you are comfortable putting yourself in other people's shoes.
• You are happy and excited to explore new technologies and techniques.
• You have a can-do attitude, can be pragmatic where necessary, and are excited to work as part of a specialist team. You can engage in constructive criticism and aren't afraid to have your code reviewed.
• You had professional exposure delivering data science solutions, ideally within a regulated or payments adjacent environment and with an understanding of regional market, customer, and regulatory considerations.
• Comfortable operating in a federated model, balancing global standards and guidance with local ownership, execution, and customer engagement.

As we are often breaking new ground, both for Mastercard and more widely in our sector, we strongly encourage exploring new technologies and techniques. Some of the following experience is therefore desirable:

• A strong academic foundation in a scientific or closely related discipline, such as data science, computer science, mathematics, statistics, physics, or engineering

• Streaming and real time data processing

• Modern machine learning approaches, including deep learning frameworks

• Network and graph based analysis to model complex behaviours.

• Development of custom data visualisations and analytical prototypes

• Work Authorization

• Eligible to work in Singapore for long term
