Senior Data Engineer - m H/F Mytraffic

Détail du poste

Mytraffic is providing 600 companies all across Europe with actionable insights (evolution of the footfall, vehicle traffic, socio-demographic information, competitor benchmarking, etc.) on the location of their choice. To compute these insights, we use a combination of data sources, including anonymized location data, demographic information, and traffic flow data. These data are aggregated and analyzed to provide detailed insights into visitor behaviors and foot traffic trends.

Mytraffic is a rapidly growing scale-up, supported by a €30 million Series B round in November 2022 from Axa Venture Partners, ALVEN, and KERNEL Investments to further develop their platform and fund their international expansion. Our ambition is to quickly become the European leader in data solutions for commercial real estate. We are already present in 10 countries and continue to enter new markets.

In January 2024, Mytraffic announced the strategic acquisition of the Spanish startup Geoblink, becoming the first European geolocation analytics platform thanks to this union.

We have an outstanding Senior Data Engineer position opened in our Data team. As a Senior Data Engineer, you will BE responsible for designing, configuring and maintaining some of the most complex data systems we use, including relational, non-relational, in-memory, persisting and distributed databases and parallel processing systems. You will work closely with our Data Science, software and infrastructure teams providing robust and read-to-scale data pipelines.

This is an exceptional opportunity to contribute to the strategic integration of Mytraffic and Geoblink's technology. You'll BE instrumental in optimizing our combined tech stack, collaborating across teams, and making crucial decisions that will shape the unified infrastructure.

So, if you are passionate about Big data, parallel computing, ETLs and interested in being one of the points of reference regarding how data and databases are architectured, structured and integrated in a fast-paced organization, then this job is for you !

- Design and implement new architecture for big data ingestion, process and storage
- Build data pipelines to automate the ETL processes of all the sources we combine
- Collaborate with Data Scientists, Software Engineers to define flexible and scalable solutions

To deliver this, you will join our talented French and Spanish team which has extensive experience in Big Data environments. You'll have the opportunity to play with a very large amount of daily updated geolocation data in France and Europe, and develop your skills and challenge new technologies that could bring more value to our technical stack.
