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.

Why this job matters
IT has become the core asset for most businesses. Our Cloud Native engineers guide our clients through this increasingly complex IT landscape. We build confidence with cloud technologies and help clients transition to a modern architecture. Our engineers also work with Cloud Native vendors on next-generation open-source tools.
What we look for
Why apply
You’ll be in charge of shaping a new IT architecture for some of the best companies in the world. We work in small, self-managed teams that take full responsibility for the projects. We’re not tech/cloud service resellers. We mix the best open-source tools and services that make sense for the project. We move fast and deliver mainly short-term projects (2-4 months), mostly working from our offices. We automate the infrastructure of our customers and deploy orchestration layers on top of it to run apps and data. All our engineers are encouraged to share their knowledge at conferences and within the company. We consider ourselves a continuous learning company. There are no rockstars here, just people that wanna grow themselves and their community. Switching between projects/roles/offices is possible and quite common.

Your mission
You'll be joining the team developing the web marketplace backend. We create the business logic both for the customer-facing frontend and for the "back-office" of the product. We work on all layers of the system from the database models to public APIs. An intrinsic part of your responsibilities would be helping us to make the right decisions since we strongly believe in team collaborative expertise, and eventually realizing and orchestrating these decisions throughout the complete product funnel.

We created Jodel to let you instantly connect, share, and engage with the community around you. We built thriving local communities across Europe and continue to expand globally. With over 1 million users creating more than 6 million posts per day, we have one of the industry's highest retention rates. We've attracted great investors such as Christophe Maire, Adam d’Angelo, and the Floodgate Fund, and even been the subject of several academic papers.
We're growing our Engineering team around a culture of sustainability and empowerment. We're dealing with dynamics such as being local, signup-lean and many more, which give us new problems to solve -- we’re literally breaking new ground in the Social Network space. Data-driven by default, with a bias for quality and code sustainability, and fostering a solid DevOps and Automated Testing culture, Jodel's Engineering team is the place to be!
Attitude we're looking for * You’re naturally motivated and proud of doing great work; * Numbers and data are the best way to drive your decisions; * You have a strong personality, sense of ownership and responsibility; * You put people and human interactions above processes and rules; * You understand the value of "measure twice - cut once" and you work by this mantra; * You own your successes and your failures, and constantly seek to improve; * You keep your mind on the product we're building, and are permanently aware of how each small action influences its success.
What we value * Your studies were in Computer Science, Mathematics or Engineering; * You're a problem solver, and you’re eager to experiment and learn new things; * You write code optimizing for clarity and readability; * You value testing very highly; * You write software aiming at reducing the cost of change; * You enjoy pair programming and code reviews, and see your job as a collaborative effort rather than solitary work; * Engineering work is mostly about compromises and so you're always open to discuss different approaches to problems; * You're happy to collaborate with your community and industry, either in open source projects or presenting at meetups and conferences;
Skills we're looking for * You have experience with either Node.js or Golang, but you're definitely interested in doing more Golang as part of your job; * You want to work in Distributed Systems; * You have experience with MongoDB and Redis, beyond "I have played with it in the past"; * You have a bias to automate things when possible; * You’re ready to embrace a DevOps culture, because an Engineer’s work doesn’t end after we ‘git push’; * You're ready to work with Linux, Cloud providers, Docker, Kubernetes
What do we offer? * An Empowered Team -- Engineering owns tech debt and tech improvement decisions; we collaborate tightly with our product team but we're all very mindful not to step on each other's toes. We own technical decisions, take responsibility and are accountable for them.. * Preventive culture, rather than reactive -- While some of us participate in on call duties, we have a very low amount of actual production emergencies. A lot of energy goes into fixing root causes and we are very proud of not having anyone in firefighting mode. * Career building is part of the deal -- you don't join to just write tests and contribute to the product - you also join to improve your career. We pay special attention to your personal development and make sure you're focusing on the skills that matter the most to you. * Lean processes -- we try hard to cut meetings and processes to a minimum, to ensure that you’re being productive. And we encourage all interactions to be direct and open, not forcing you to go through any intermediaries to get your work done. * United in diversity -- with people from all over the world, from Tunisia to France, from India to the Poland, we are multicultural by default and proud to be so. We all come from different walks of life and cultural backgrounds, and we continue to push for diversity in our team! * We're building a team, not just making money -- we solve hard problems together but we also relax and have fun. From team cooking to going on company trips, from office parties to go-karting, we'll make sure you have a good work-life balance. * The future will be amazing -- the list of non-trivial challenges we'll be dealing with includes developer APIs, security issues, scaling access to a lot of data (among other things we can't tell you about :-) ); all of this with location and anonymity as their own dimensions in Jodel. * No one else is doing what we're doing -- it's that simple. We're pioneering local communication and since communication is a basic human need, our work is super exciting. On top of that, we are one of the few large scale European Social Networks. There’s not that many and we're very proud to be "Made in Europe".
