Trusted Shops AG • Cologne

Cologne

from today / asap

Your duties

Trusted Shops develops SaaS solutions for over 30 million users and 30,000 businesses across Europe. Our product suite includes products such as the Trustmark, Buyer Protection and the eTrusted experience feedback platform. Our products are part of a 20-year mission to enable trust between people and businesses in the digital age.

Home of our product development is the Products & Engineering department, which consists of 14 cross-functional Product Teams across 3 product domains (Consumer, Business and Platform), working in an agile environment.

What your role is about:

  • Develop and maintain data pipelines using ETL/ELT processes to ensure seamless data flow and integration.
  • Write and debug analytical queries to extract valuable insights from data.
  • Develop APIs to provide frontend applications with dynamically filtered and aggregated data.
  • Design data models optimized for retrieval via data-APIs for data exchange or customer-facing frontends.
  • Architect data-intensive applications to handle large volumes of data efficiently.
  • Integrate with existing data integration processes within the data platform.
  • Enhance and quality-assure existing OpenAI integrations, and implement new requirements in the field of Natural Language Processing


Why you should join Trusted Shops:

  • As the most relevant asset, we care for teams and the organisation. Your Engineering Manager actively supports you in your personal development and works on removing organisational impediments.
  • We care about your health with monthly health activities and give you 1 additional day of holiday if you collect enough ‘Health Activity Stars’ in a year.
  • We care about your education – every last friday of the month is the self education friday, where you can join our internal tech talks, read a book or take time to work on your goals.
  • If you want to know more about our organisation, feel free to check out the LinkedIn articles of our CTO: https://www.linkedin.com/pulse/working-system-andr%25C3%25A9-neubauer-cfmpf/

What your day as a Senior Data Engineer (f/m/d) might look like:

  • Starting your day with setting up your mobile working environment – or adjusting your table at the office.
  • Opening your individual task manager and getting your mind into the stories you are working on at the moment – from short term operative to long term big stories being part of even larger epics.
  • Meeting with the team in the daily standup and setting the stage for the collaborative work of the day. You’ll probably have a look at your backlog together – or your Kanban board or whatever style of agile collaboration the team favours.
  • You continue working on the stories, tasks and bugs from the current sprint or the Kanban board. Do some focus time coding session alone or work on issues together in a pair or mob-programming session.
  • Lunch break! Grabbing a bite at home with your SO or maybe gathering a few colleagues and explore the restaurants around the office?
  • In the office today? Maybe Waffle Day or Health Day? Don’t forget to grab freshly baked waffle or a Smoothie before getting back to your desk.
  • Work sessions and maybe some meetings in the afternoon. It is completely up to you and the team how long and in which constellations and formats you work!
  • Still in the office? Get a free drink on the rooftop terrace before going home, maybe? And remember: We don’t believe into working till the middle of the night here.
  • Or was this your monthly self-education day? In which case, no meetings for you today, but a self-chosen agenda of learning and self-improvement.

Your profile

  • Extensive years of experience in a Cloud-based environment, particularly in the field of Data Engineering.
  • Familiarity with AWS services like Athena, Glue, Lambda, and CloudWatch is a strong advantage.
  • Proficiency in ELT processes for Data Transformation, coupled with Hands-On experience utilizing Orchestration Frameworks such as Luigi, Airflow, Prefect, or Dagster.
  • Thorough understanding of common Data Formats (CSV, JSON, Parquet, etc.) and typical Data Interfaces.
  • Demonstrated expertise in essential Data Concepts, including Data Lineage, Data Quality Management, Data Privacy (GDPR) Compliance, Observability, and Incident Management.
  • Highly skilled in Python and SQL; additional knowledge of Terraform and Bash Scripting is considered a Bonus.
  • Fluent in English. Proficiency in German is an advantageous asset but not mandatory.

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 Angular and React frameworks in the frontend and also on the server side with NodeJS 

Kotlin: We sometimes use Kotlin as an alternative to Java for server-side solutions and for our mobile development 

Python: We often use Python when processing or transforming data. We also occasionally write services in it with the help of AWS Lambda 

Frameworks
Frameworks

Angular: Particularly in our B2B area, we rely on Angular for our frontend in order to be able to develop interactive solutions efficiently 

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 Kubernetes clusters 

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.

Frontend Developer

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.

Data Analyst

I have been working as a "Data Analyst" at Trusted Shops since mid-2021 and work independently and in collaboration with colleagues on the topic of data. I have made it my task to provide automated, data-driven, real-time insights for customer success management in order to initiate measures for customer-oriented solutions and decisions. This is done through independent analysis, defining and determining KPIs, and creating dashboards. I enjoy supporting my team and Trusted Shops in achieving our goals with these data-driven topics day after day.
