Senior Software Engineer - Back End

With $5.0B+ in transactions since inception, Eventbrite operates one of the largest scale payments platforms in the world. In addition, the Eventbrite platform facilitates communication between organizers and their attendees, sending millions of emails per month. A successful site integrity engineer has a single goal: to accurately stop fraud and spam in a way that is frictionless to the end user while scaling both operationally and technically.

The Site Integrity team is a small group that builds infrastructure and tools to prevent abuse on the Eventbrite platform. Systems built by our team are used in the most critical parts of our site and must scale gracefully with the growth of the company. Learn more about the team from some of our engineers.

As a Senior Engineer, you'll be architecting and implementing performant systems as well as coordinating with our operations team to ensure that they run smoothly.  You'll collaborate with engineering, product and other business stakeholders to scope and design products correctly.  You'll perform code reviews, mentor other engineers and contribute to a robust learning culture.  You'll be proactive, curious and accessible.

The risk infrastructure is a Python-based service that can be queried by other systems at Eventbrite.  For datastores, we lean heavily on MySQL, Cassandra and Redis.  For our machine learning, we use scikit-learn.  We also build tooling within the main Eventbrite Django application and do a fair bit of data collection, which is transmitted via Kafka to downstream consumers.
