Hackathons

We like to think outside the box, developing useful and creative solutions to problems during small events – whether related to work or not

Peer- /mob-programming

Many people work together to develop the best code. This allows us to progress even more effectively in projects and to learn from each other.

Everyone can offer knowledge or search for it on a kind of bulletin board. This creates spontaneous training sessions with each other

Are you passionate about the code behind our products?

Programming Languages

Java: Java is used by some of our Tech teams and supports us with components that have complex logic, usually in combination with Spring Boot

TypeScript: We use TypeScript combined with the React framework in the frontend and also on the server side with NodeJS

Python: We often use Python when processing or transforming data.

Frameworks

React: React is used when the performance of our solutions is important. Our B2C environment, in particular, benefits from React (shop profiles, trust badges, widgets, etc.)

Spring Boot: When it comes to complex business logic in Java and Kotlin, we use Spring Boot. It is deployed in ECS

NodeJS: Our focus is on serverless, and we often use typescript in the backend. We mostly use NodeJS in combination with AWS Lambda

Service & Tools

Circle CI:  CircleCI is our CI/CD tool for automated builds, testing & deployment

GitHub:  GitHub supports our internal open source policy and enables cross-team cooperation and feedback

Ansible: We use Ansible to provide our virtual servers in a repeatable and automated way

Terraform: Our AWS infrastructure is fully managed with Terraform. This allows us to keep a simple history of all changes and minimise the manual effort.

Databases & Hosting

DynamoDB: DynamoDB is often used to access large amounts of data in real time. We regularly use it with AWS Lambda to provide a scalable solution.

PostgreSQL/MySQL: If flexibility of data access is paramount, then we also use relational databases

AWS:  For us, it's "cloud first" so that we are able to scale the infrastructure of our products. Here we rely on services such as AWS Lambda, S3 and DynamoDB

Employee reviews

Right now we are working on a new major project for user management and permissions, which is interesting but also complex and has many aspects that will allow it to be integrated into other components. I really like the fact that, as developers within the team, we can decide which technology and programming language we want to use and how we structure the processes. This can sometimes be a challenge, but it helps us gain a lot of new experience. I can work on anything I want to learn about on self-learning days. And of course we have a very friendly and open working atmosphere. Team building events and mob/pair programming sessions also contribute to this.

I am currently working in the Review Insights team. In this product team, we work on frontends that help our customers, i.e. online retailers, to draw valuable information from the collected reviews. I have another colleague in the team from the front-end team with whom I work closely. This starts with the planning and discussion of solutions and ends with the joint revision of the written code. Overall, the working atmosphere at Trusted Shops is very pleasant and relaxed. Thanks to a specially developed platform solution, each product team can build its own micro frontends and is thus independent of the other product teams. This means that you are not restricted in your choice of framework, for example - however, we mainly use the common JavaScript frameworks. Personal development is also encouraged. This year, for example, I was able to take part in a one-week summer school on the topic of deep learning, and we basically have one day a month at our disposal to continue our education as we see fit.
