Our environment of discovery and innovation means we’re able to create deep and valuable relationships with our clients to create real change for them and their industries. It’s what got us here – and it’s what will make our future.

We're heading in one direction, the future. We’d love you to join us.

At Quantexa we believe that people and organizations make better decisions when those decisions are put in context – we call this Contextual Decision Intelligence. Contextual Decision Intelligence is the new approach to data analysis that shows the relationships between people, places and organizations - all in one place - so you gain the context you need to make more accurate decisions, faster.

Founded in 2016 Quantexa helps organizations make their data more meaningful, and is the world’s leading software company providing a single networked view of internal and external data as an input to analytical and AI models. From compliance, fraud, anti-money laundering and credit risk to customer intelligence and master data management, Quantexa partners with Global Tier 1 Insurers and Banks, Government Agencies, Telecoms and Technology companies to deliver Contextual Decision Intelligence.

Due to the continuous success and high demand from our customers, we are looking for a Lead-level Scala Engineer to join our R&D team to build and shape the next generation of products that transform how organizations around the world use data.

Headquartered in London with significant offices in New York, Boston, Toronto, Sydney, Singapore, and Brussels and Malaga Quantexa is continuing its expansion within the UK, building on our core values of Determination, Ambition, Teamwork and Accountability.

What will you be doing?

You’ll be joining the Research and Development department where you will be working on our core Contextual Decision Intelligence offering: The Quantexa Platform. The Quantexa Platform helps our Customers solve business problems in areas such as fraud, financial crime, data management and many more. Our products process, analyse and display huge volumes of data with the ultimate aim of detecting anomalous and suspicious activity.

The R&D department consists of nearly 200 people split into agile teams of Engineers, DevOps, Data Engineers and Scientists, Designers, QA and others each focusing on specific projects and areas of the Platform.

Our back end services are primarily written in Scala and deployed as microservices. We are huge fans of functional and strongly typed programming, making use of libraries such as Cats and Shapeless. We use Pekko and Cats-Effect to help build scalable, highly performant, distributed systems. We utilise techniques such as event sourcing and CQRS in our persistence layer to ensure our datastores are scalable and flexible.
