About Integrations team at 6sense

The Integrations team is responsible for various data integrations with our customers and partners: from ingesting large quantities of data into our data warehouse to exporting processed results back into external systems. We have built highly scalable systems that can ingest billions of new records on a daily basis. This data feeds into our ETL pipeline that processes the data for consumption by the 6sense platform.

We have also built low-latency APIs that match an IP address or email-address to a company. This helps our customers and partners tap into our best-in-class company ID graph and enables various real-time personalization use cases on their websites or backends. The distributed nature of the user-base, the scale of the data and the response time requirements provide unique challenges that require a sophisticated API architecture.

The team consists of engineers at different levels of experience, covering a broad range of skillset but united by a shared drive to build great things. The team is growing in lockstep with the overall company, to take on bigger challenges. There are ample opportunities to learn and grow and build cool products.
