Senior/Lead Full Stack Software Engineer

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 with only a handful of individuals, Quantexa was built with a purpose that through a greater understanding of context, better decisions can be made. 8 years, 8 locations and 500+ employees later we still believe that today. We connect the dots within our Customers data using dynamic entity resolution and advanced network analytics to create context, empowering businesses to see the bigger picture and drive real value from their data.

Due to the continuous success and high demand from our customers, we are looking for a Senior Full Stack Python Engineer to join our growing 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, 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 Quantexa's dedicated Research and Development team which is at the heart of everything we do here. The team is continuously working on new and innovative products, helping our Tier 1 clients solve business problems in the area of fraud, compliance and financial crime. Our products process and query huge volumes of data with the ultimate aim of detecting anomalous and suspicious activity.

The R&D department consists of over 100 people split into agile teams of Engineers, Product Managers, Designers, QA, and others each focusing on specific projects and areas of the Platform.

The user interface is highly visual and data rich, allowing users to navigate and interact with social network diagrams as well as view output from our back end analytical processes. The application itself has been developed using modern front end tools and frameworks such as TypeScript, Angular 15 and ngrx and has been designed from the ground up to be highly extensible and allow for customisation to meet our clients requirements. In this role you will be working on building new investigation features and components, developing data visualisations and improving the UX to ensure our users can work with the application as effectively and efficiently as possible.

On the back end, our 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 also use Akka and Monix to help build scalable, highly performant, distributed services. We utilise techniques such as event sourcing and CQRS in our persistence layer to ensure our datastores are scalable and flexible.

We are looking for candidates who:

• Take pride in designing, building, and delivering high quality well engineered solutions to complex problems.
• Have experience functional programming using Scala AND/OR experience using modern front-end frameworks, ideally Angular 15+.
• Have experience with the full engineering life cycle, from design and implementation through to testing and deployment.
• Experience with DevOps tooling and approaches (automation and tooling is something we are passionate about, we even have a dedicated Developer Tooling team)
• Take a big picture approach to solving problems, taking care to ensure that the solution works well within the wider system.
• Love working with the latest technology.
• Passion and drive to grow within one of the UK’s fastest-growing Scale-ups.

Experience in the following would be beneficial:

• Working across the entire software stack from the server‐side and batch processing components to the front‐end web development.
• Has a keen eye for detail with regards to design and UX.

• Knowledge working with any of the following technologies or libraries: Akka, Monix, Cats, Shapeless, Spring Boot, Elasticsearch, Gradle, Apache Spark, Hadoop, Docker, Kubernetes.

• Experience with Cloud technologies (we use GCP internally)
• Experience building software which deploys to both on-premise and cloud Environments
