About the job:

In Scrapinghub, we are developing a next-generation platform for automatic crawling and extraction - a combination of using the state-of-art machine learning technology and scaling it up with microservices.

The platform would be used directly by our customers via API, as well as by ourselves for internal projects. So far our extraction capabilities include automated product and article extraction from single pages, and we plan to expand it to support whole-domain, and also support more page types like jobs and news. The service is still in early stages of development, serving its first customers.

Our platform has several components communicating via Apache Kafka. Most components are written in Python, with a few components implemented with Scala and Kafka Streams. The current priorities are improving reliability and scalability of the system, integrating with other Scrapinghub services, and adding new features like auto-scaling. This is going to be a challenging journey for any good backend engineer!

Apply and join an excellent team of engineers and data scientists, including one of the world’s top-ranked Kaggle masters!
