Big data flows powering search experiences

How do you make our customers happy?

Bol.com is the leading online retail platform in the Netherlands and Belgium, serving 13 million customers with 129 million monthly visits across 41 million products. As a Senior Data Engineer for Search, you’ll help connect customers to the right products by ensuring our search engine has access to perfectly processed, real-time data. Your work directly impacts customer satisfaction and helps sellers showcase their products effectively.

What you do as Data Engineer for Search

You’ll process massive datasets from multiple sources in real-time and batch, optimize performance to handle thousands of requests per second, and design/maintain ETL/ELT pipelines using Google Cloud Platform. You’ll collaborate end-to-end on new features, work with stakeholders to solve technical challenges, and contribute to a clean microservice architecture using Go, Kotlin, and Python. You’ll help pivot the team towards creating more insights for consumer journeys and expand our user interface for business users.

Core Responsibilities:

• Process massive datasets in real-time and batch
• Optimize performance for high-volume, low-latency requests
• Design and maintain ETL/ELT pipelines (GCP)
• Collaborate on new features from design to deployment
• Work with stakeholders to solve data challenges
• Contribute to technical decisions and architecture

3 reasons why this is (not) for you

• You prefer flying solo – You prefer coding alone and dislike cross-team collaboration
• You crave instant gratification – You need immediate, individual results rather than team-based impact
• You’ve stopped being curious – You believe you’ve already mastered everything there is to learn
• Data is your playground – You enjoy working with large, complex data systems
• You think big-picture – You want to contribute to strategic business assets
• Collaboration is your superpower – You communicate well and enjoy teamwork

This is where you’ll work

You’ll join the Search Department at Bol.com, working in a team that aggregates and enhances all available data to optimize search and provide insights for customer journeys. The team consists of four other engineers and a product manager, collaborating closely with other teams in the department. Bol.com values diversity and innovation, embracing AI coding assistants with a “use but verify” approach.
