Job Title

Data Science Operations Engineer

We build products and services powered by payments data to find and stop financial crime. By combining data science technique with an intimate knowledge of payments data we develop solutions that will improve outcomes for people, businesses and economies. Headquartered in The City of London, and operating globally, we craft bespoke algorithms that help our clients gain an understanding of the underlying criminal behaviour that drives financial crime.

As a Data Science Operations team member you will be responsible for the day to day operations of the Financial Crime Solutions product portfolio, building automated systems to support the monitoring and operation of our services. You will work with a wider team of product owners, data scientists and technologists, designing systems that ensure the efficacy and efficiency of our products.


Reporting to the Director of Data Science Operations - Financial Crime Solutions, the Data Science Operations Senior Analyst will:

• Build automatic monitoring tools for data science based microservice deployments. Ensure that our models are continuing to detect financial crime as they should.

• Working with our Data Scientists collect data and train models to enhance our services’ accuracy and reduce unnecessary alerts.

• Working with our Engineers, seek to develop a self-healing and resilient set of microservices, promoting good operational principles during our research, design, and development phases.

All About You

Your passion is in building robust, smooth running services to solve real, pressing problems in the financial services sector. You enjoy working in a team, and have an interest in data science and how advanced algorithms may be deployed as product offerings.

You are excited by new technology and new approaches to development, and are keen to promote their use in an enterprise setting. You are detail oriented, and don’t mind getting your head down writing or reviewing code. You are happy to be on-call, though you aim to contribute to Financial Crime Solutions’ software in such a way as to limit or even remove the need for anyone to be on-call.

• You have 2 or more years’ worth of demonstrable experience in software development, data science, devops, operations or a related discipline.

• You are comfortable communicating with a range of stakeholders, including subject matter experts, data scientists, software engineers and enterprise devops and security professionals.

• Able to deploy containers onto a Kubernetes environment using helm charts.

• You have experience with, and are interested in, contemporary approaches to service design, including the use of containers and container orchestration technologies, streaming data platforms, APIs and in-memory/NoSQL stores.

• Ability to engage with best practices for code review, version control, and change control, balancing the need for a quality codebase with the unique and particular demands of early stage product design and delivery.

• You have an understanding of traditional data warehousing and can write SQL.
