(Senior) Backend Java Developer - Marketing Technology (f/m/d)

• You will be part of the Marketing Technology Engineering team. This team is responsible for supporting all the Holidu Marketing teams with technology solutions that enable and scale their efforts to optimise the campaigns and effectively reach their target audiences. 
• Your team will consist of 3 software engineers.
• You will be responsible for various tools that help automate the extremely complex and massive process of configuring different marketing channels. For example, Google, Microsoft and Apple ads, just to name a few.
• You will work in close collaboration with our data analytics and data engineering teams in Business Intelligence as well as the Marketing teams themselves by providing them with data on the Marketing performance.

Java Applications and SDK Development: Developed in Java, our applications provide integrations with multiple marketing channel APIs, pulling and pushing data to them. Highly concurrent and efficient in their approach, they interact with significant data volumes, cheaply and quickly.  Deployed as microservices on an AWS-hosted Kubernetes cluster (EKS), our architecture ensures scalability, resilience, and efficient management of workloads.

Rich Data Environment: We use Airflow as a scheduler and Data Build Tool (dbt-core) to craft efficient data pipelines with an extensively customised setup leveraging the flexibility of Python. We interact with data seamlessly using Redshift, Athena, and DuckDB. Our Redshift setup employs a decentralised structure via Data Sharing, enhancing flexibility and scalability.

Comprehensive Cloud and DevOps Integration: Our tech arsenal includes Terraform, Docker, 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.
