About Fraugster:
Fraugster is a payment security company with the goal of eliminating fraud and increasing our customers’ profits. Over the last years we’ve invented an artificial intelligence technology that combines human-like accuracy with machine scalability. This ability lets us foresee fraudulent attacks before they actually happen and gives us a distinct competitive advantage over every other player in the payment security space.
We’re already working with some of the most well-known payment and e-commerce companies in the world. Notable clients include companies like Ingenico, SIX Payments and others. Fraugster is backed by top tier investors and is currently managing billions of Euros for our clients.
Development at Fraugster:
Our stack uses Go exclusively for back-end APIs. Functionality is spread across multiple services which communicate via gRPC. Relational data is stored in Postgres and other types of data are held in other non-relational data-stores such as etcd and Kafka. All services are containerized and deployed to kubernetes. Our frontend client is implemented in Angular 7 (Typescript).
Our development process is lightweight Scrum with 2 week iterations. Code is contributed to projects via merge/pull requests which are peer reviewed by colleagues. Code is continuously integrated, tested and checked with automated CI pipelines.
As a team we value shared ownership of our code, design simplicity, code cleanliness and continuous improvement of products and processes.
Job Description:
You would be joining our cross-functional team to help us develop our customer-facing web application.
As a full-stack developer you would be responsible for implementing new features across multiple levels of our stack, assisting with the maintenance of our existing codebase/infrastructure and contributing to our overall development workflow.
The ideal candidate would be enthusiastic in helping us improve our engineering culture and quality, bringing new ideas to the table and helping us achieve clean, maintainable code and architecture.
The following skills represent the perfect skill-set of a candidate but we understand very few developers fit this profile exactly. As such, we would welcome candidates that can bring deeper knowledge of a subset of our requirements to our team, even if they have limited experience in other areas.
