👫 About the team

At Equativ, we’re on a mission to develop advertising technologies that empower our customers to reach their digital business goals. This means that we rely on massively scalable, widely distributed, highly available, and efficient software systems; the platform deals with over 100 billions requests per day and above 40 Gbps of network traffic. 

Our innovation team based in Paris, Nantes, Limoges, Krakow and Berlin is composed of 90 straightforward and energetic engineers working in an Agile environment and ready to tackle the most complex technical challenges.

Our data engineering team is composed of 10 skilled engineers and is based in Paris. We are part of the R&D department which is composed of 140+ engineers spread across Paris, Nantes, Limoges, Kraków and Berlin all working in an Agile environment and ready to tackle the most complex technical challenges.

Our Mission 👇

Data Engineering team is central to Equativ’s data centric business and is responsible to ingest, transform, model and redistribute all data coming from our adtech platform.

We aim at building scalable and robust Big Data platforms from ingestion to business actionable consumption. Our Big Data ecosystem must handle massive log ingestion (tens of billions per day), short & long term data storage, complex data modelling, real-time and batch ELT as well as providing external access through dedicated APIs.

Data Engineers serve Equativ data directly to our customers and throughout the company whether it is for BI analysis, data science algorithms (clustering and optimization), customer reporting, invoicing and more.

Equativ Data Engineering team is engaged in an ambitious migration of its main data stack (Hadoop on-premise) to GCP with the objective to increase reporting features, lower maintenance time, improve performances and simplify the access to our raw data.

What you'll do ✏️

    • As a Big Data Engineer, you’ll primarily focus on maintaining and enhancing the operationality of our on-premise and cloud data pipelines which feed our warehouses and APIs

    • Design, develop, test, promote and industrialize all data components from data ingestion to datawarehouse delivery (ClickHouse, BigQuery)
    • - Propose and develop innovative solutions to achieve the best levels of scalability and performance for our Big Data engines
      - Automate and streamline our real-time and batch data pipelines (on-premise and in the cloud) in order to simplify access to our data by other teams and lower amount of work spent by other teams on ETL processes
      - Perform end-to-end monitoring to ensure high availability of production data processing, data quality and reliability
      - Apply best in class Devops guidelines and secure deployments

    • Brainstorm with other team members working on our data backend (datawarehouse modelling and data exposure through our reporting APIs) on optimizing our architecture and support them in the use of our pipelines
    • Contribute to data roadmap definition in coordination with other R&D and product teams in order to build a best in class data infrastructure that will generate insights for Equativ’s analytics
