Your future team

You will be part of the Data Engineering team in the Business Intelligence department. This team is responsible for creating, maintaining, and refining the core data pipeline tools, as well as supporting several end-user pipelines. Your team will assist the organization in addressing all its data needs and, simultaneously, enhance the data platform with new capabilities and refactoring.

Your team will consist of 5 data engineers (3 Seniors, 1 Tech Lead manager and 1 Staff Engineer). You will work closely with the data analytics and data science teams to enable them to leverage further the tools you have built, as well as develop and automate best practices for handling data on our platform.

Our Tech Stack

Rich Data Environment:

We use Airflow as a scheduler and Data Build Tool (dbt-core) to craft efficient data pipelines with an extensively customized setup, leveraging the flexibility of Python.
Utilizing Redshift, Athena, and DuckDB, we interact with data seamlessly.
Our Redshift setup utilizes a decentralized structure through data sharing, enhancing flexibility and scalability.
The everyday tasks associated with data warehousing are effectively automated through the proficient application of the Spring Boot CLI, thereby streamlining operations and ensuring operational efficiency.
We utilize AI (LLM) tools extensively to enhance productivity. (Claude, Copilot, Codex, MCP Servers, Agentic systems, or tool of your choice).

Comprehensive Cloud and DevOps Integration:

Our tech arsenal includes Terraform, Docker, and Jenkins, forming a robust foundation for cloud-based development and seamless DevOps integration.

Detailed Monitoring Capabilities:

Monitoring is a top priority, and we employ ELK, Grafana, Looker, OpsGenie, and internally developed technologies to ensure real-time visibility into system performance and data workflows.

Data Ingestion Platform:

Build and maintain Java microservices that collect user tracking data from our websites and mobile applications via REST APIs, using Kafka as the central message broker.
Deploy applications on AWS EKS (Kubernetes), ensuring high availability, scalability, and efficient resource management.
Develop Java/Kotlin SDKs that enable backend development teams to send user event data to Kafka and AWS Firehose seamlessly.
Architect event-driven data collection systems processing millions of user interactions daily from across our digital properties on systems handling millions of events daily with sub-second latency requirements.
Configure and optimize third-party ingestion tools (Airbyte, Fivetran) to extract data from external APIs, databases, and SaaS platforms.
