Software Engineer I - Data Solutions

About us: At Booking.com, data drives our decisions. Technology is at our core. And innovation is everywhere. But our company is more than datasets, lines of code or A/B tests. We're the thrill of the first night in a new place. The excitement of the next morning. The friends you encounter. The journeys you take. The sights you see. And the memories you make. Through our products, partners and people, we make it easier for everyone to experience the world.

About the team: Data Streaming track

The Data Streaming track is responsible for building highly scalable, reliable, compliant, and flexible solutions that move Booking.com's data from diverse sources into our internal data warehouse. These sources span both on-premise systems (such as Cassandra and MySQL) and cloud platforms (including AWS RDS). Our solutions are often heavily customized to meet the needs of different systems, business domains, and stakeholders.

We focus on two complementary areas:

• Snapshotting: The team designs and maintains snapshotting solutions for all major databases. We currently run more than 2,000 pipelines that are critical to the entire company, and our goal is to ensure they succeed on time, every day, with six nines of reliability.
• Streaming
  We are also building streaming solutions that bring data into the warehouse almost in real time. This work comes with unique engineering challenges, as we operate on highly active sources where data is constantly being inserted, updated, and deleted.

Reliability and observability are at the core of everything we do. We invest heavily in monitoring, alerting, and recovery strategies to ensure that pipelines can handle the scale and complexity of Booking.com's data while remaining robust against failures.

Our stack includes AWS services (Lambda, EC2, DynamoDB, Step Functions), and we rely on Java, Python, and Flink to power our pipelines and solutions.

Role Description: In this role, you will be responsible for designing and delivering software solutions that meet business requirements, while steadily developing your own technical craft.

You will also play an active role in supporting our production systems, addressing and resolving live issues quickly, and minimizing customer impact by working within defined SLAs. This position offers the opportunity to grow your engineering expertise while contributing to reliable, business-critical data solutions at scale.
