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.
Desirable Skills:
Comfortable designing and developing GRPC/HTTP APIs with Go
Experience in at least one modern front-end framework, preferably Angular (2+) with Typescript
Knowledge of standard web development technologies including HTTP, CSS/SCSS, ECMAScript, HTML, bundling and testing tools
Experience containerizing and orchestrating infrastructure with tools such as Docker and Kubernetes
Interest in working with relational databases such as Postgres or MySQL
Previous exposure to non-relational data infrastructure including queues (Kafka), indexes (Elasticsearch) and key/value stores (etcd) would be desirable but not required
Business fluent in spoken and written English
What we offer:
Hands-Âon experience in building a product that’s revolutionizing the payment security industry
Technical challenges to solve with a real world application
An environment open to adopting new technology and ideas
Your own projects and opportunity to shape our Front End stack
Competitive salary
Office located in the heart of Berlin

October 2018

More Than 6 Months Old

Job Description
*The product: A containerized data science environment*
Our ambition is to create a platform that gives data scientists a flexible, consistent, and simple environment based on Docker containers, where their code can be written in a large variety of languages (Python, R, Go, Scala). This tool then turns their code into stateless functions that can be easily deployed into powerful data pipelines.
*The stack*
Kubernetes, OpenFaas, Docker
*The challenge*
Having great DevOps engineering support is crucial in order to guarantee that our micro-service based platform runs smoothly and reliably, no matter where it is deployed (we support cloud and on-premise deployments).
Our components are mostly written in Go, with some Scala and a bit of Python mixed in, and all of them expose well-defined interfaces. We always keep operational requirements in mind when developing new services.
We're looking for someone who can actively drive our roadmap in the area as part of our technical operations team, who can evaluate new technologies and wants to be a great partner for the rest of the tech team.
*Your profile*
You have senior-level experience with complex production deployments, know your way around Kubernetes and have in depth operational experience with at least one of the big three cloud providers (AWS, gcloud, Azure).
Software engineering experience is a big plus, particularly in Go.
*About us*
*Who we are*
Contiamo is a Berlin-based, fast-growing tech company. We offer a flexible data platform enabling businesses to create interactive, data-driven decision tools and automations. Our mission is to combine sophisticated data science with a great user interface and experience.
We are a tech-driven company and keep a close watch on recent scientific developments and emerging technologies. We love open-source. We are a very international team with interesting people from all over the world (95% of us have relocated to Berlin).
*How we work*
We strongly believe in the importance of uninterrupted time to get stuff done and quality over quantity when it comes to working hours. We prefer to keep our schedule meeting-light and work in a library-like atmosphere during the core hours.
We believe the ability to give and get constructive feedback and express divergent ideas is crucial to making innovation come to life. We live a very open discussion culture and prefer the evaluation of ideas based on merit over top-down decision making.
We strongly believe in ownership of one's features, from spec to implementation to operation. We also understand that ownership comes with a sense of responsibility towards others that depends on the results of our work.
We believe that everybody should be able to find meaning in their work. We match assignments based on both ability and individual interests and discuss your progress and individual needs every 3 months.
We don't see people as "resources" and genuinely care about each other. We also understand that there's more to people's satisfaction and engagement than fancy perks and cool events. We continuously work towards an environment providing a lot of autonomy, transparency and development opportunities and rely on everybody's feedback to hold us accountable for maintaining our high standards.
Sound like the kind of atmosphere you would work well in? We're looking forward to receiving your application! We see the interview process as a mutual opportunity to get to know each other — at eye level. That's why we always strive to respond within hours, not weeks.
