from today / asap

Your duties

Trusted Shops develops SaaS solutions for over 30 million users and 30.000 companies all over Europe. Our product suite includes products such as the Trustmark, buyer protection and the experience feedback platform eTrusted. With our products we pursue the mission to enable trust between people and businesses in the digital age over the last 20 years.  

The Data Platform Team contributes to this mission by providing the foundation of data-driven work, both for our colleagues, and for our customers. Ranging from metrics that measure our product usage and success, to facts and figures that provide guidance to our customers to improve their business. 

All these outcomes require quality data, and that’s why we are looking for a Data Engineer that thrives in a creative, changing environment, loves to build great products, and is passionate about positively impacting the user experience.  

You will support a diverse team. We have Data Engineers, Cloud Engineers, Analysts, and support from a Product Owner and Agile Coach, working as a cross-functional team.  

We believe in the "You build it, you own it" philosophy, where you take charge of shepherding changes through every stage until they go live in production.  


What will you be working on?
 

In your role, you will write Python and SQL, with the potential for some Terraform. Your focus will be in supporting and enabling the team colleagues but also being part of the implementation topics. You should be comfortable building data applications in a cloud environment (we use AWS). 

Our applications use a wide range of data engineering tools, such as Airbyte, AWS Kinesis Firehose, Dagster, DuckDB, Luigi, Iceberg, Metabase and many more to achieve our goals of providing services and APIs, orchestrating data ingestion and transformation journeys from source systems to high quality datasets. We currently are focused on building the Analytics Layer, an API which provides aggregated datasets at low latencies. You’ll be supporting us in making all this happen at scale. 

What your main tasks and responsibilities will be: 

  • You build and present standard interfaces to ingest, transform and serve data within the Data Platform 

  • You take ownership of implementing, monitoring, and maintaining data pipelines. 

  • You ensure data quality and transparency of our data, using quality checks, monitoring, and alerting across the entire data lifecycle. 

  • You collaborate with the team to identify opportunities which further innovate the Data Platform, leveraging existing or new technologies. 

  • You onboard our data providers, lowering the barrier to provide data to our platform. 

  • You communicate with stakeholders and team members to identify their needs and can translate these requirements into tangible outcomes. 

 

Why join Trusted Shops? 

  • Personal Development: You’ll receive direct support from your Engineering Manager, ensuring your growth and success. 

  • Health & Wellbeing: Participate in monthly health activities and earn an extra vacation day for achieving health goals. 

  • Continuous Learning: Enjoy your “Self Education Day” every last Friday of the month, where you can focus on personal growth, attend internal tech talks, read a book, or work on your goals. 

  • Inclusive Work Culture: Flexible working options and a focus on work-life balance. 


A typical day as a (Senior) Data Engineer (f/m/d) at Trusted Shops:
 

  • Time to get started, either from your home, or at the office. 

  • Open JIRA, our task manager, and pick a topic you’d like to work on: a quick win, or maybe the start of a bigger project? It’s up to you. 

  • Check in with us in the daily standup. Need any help? We’re here for you. We tend to keep dailies focused and short, but we’ll also stick around for small talk every now and then. Who knows, maybe your teammates are working on something interesting, and you’d like to join? 

  • Depending on the daily, you’ll start working alone for a bit, or maybe you decided to tackle something in a pair or mob programming session? 

  • Lunch break! We’re flexible between 12:00 and 14:00. If we’re in the office together, maybe we’ll visit our favorite lunch and coffee places in Cologne. 

  • In the office today? Maybe it’s Waffle Day or Health Day? Don’t forget to grab a freshly baked waffle or a smoothie before getting back to your desk. 

  • Had a good lunch break? Let’s continue what you’ve started before lunch, either on your own or with the team. 

  • Let’s call it a day! If you’re in the office, there are free drinks on the rooftop terrace, if you’d like. 

  • Or maybe it’s the monthly self-education day? In that case, there’s no meetings! You’re free to pick something you’d like to learn and improve on. There’s also Tech Talks, where you can learn from your colleagues.

Are you passionate about the code behind our products?

Programming Languages
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
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
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
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

Backend Developer

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.
