About the role

As a software engineer, you will help further develop our scalable, cloud-based, next-generation banking platform.

In this role you will be part of a team responsible for the development and maintenance of key Listing products/System features (Java/Python). Working with other team members to investigate design approaches, prototype new technology and evaluate technical feasibility you will assist with Architecture and Design of new and current systems.

The platform is built in Java on AWS infrastructure with AWS services and Open Source frameworks used. Delivery follows the LESS (LargeScale Scrum) methodology and we will be building automated test suites using tools such as Appium, Selenium and Cucumber.

Whilst our desire is to hire full stack engineers we appreciate that is a challenge so we accept that some of the engineers we hire may be biased towards one part of the stack. Whilst not all of our design and tooling decisions are yet made we are delivering currently on web front-end and app in React, Node.js, React Native, redux and the IOS/Android SDK’s and building our back-end in Java 8 & Spring microservices running on DynamoDB/Cassandra/Kafka.

A successful candidate will have an established background in developing customer-facing experiences, great communication and organisational skills, a motivation to achieve results in an environment eager to learn and, of course, a passion innovation. We'd love to have you join us and build the systems, services and apps that delight our end users and enable our teams to move faster.
