What our team does
The EventDB team of 7 as part of the Security Data Lake productline is responsible for SentinelOne's highly scalable columnar database. Ingesting hundreds of billions of events every day, handling billions of objects and enabling search-ability and insight for our customers into their data. With blazing speed, queries returning in milliseconds, and immediate querying of live and historical data at petabyte scale. Born from our acquisition of Scalyr/DataSet in 2021, EventDB is not just a regular database; it is engineered to efficiently scale to exabytes, serving as a critical component in our security and data infrastructure.
Our team solves non-trivial scale and data problems with a unique blending of cloud, distributed systems, and software optimization techniques and services.
We're seeking a seasoned colleague, able to lead features/epics, inspire others as Staff engineer, and lead them technically.

- You’re passionate about building high-scale elegant and simple distributed systems - and during the past several years you’ve successfully designed & implemented them (using Java or similar), to solve complex problems.
- You enjoy a collaborative development process using design discussions and code review.
- You’re looking for a challenge that doesn’t just require you to use technologies like Kafka and Cassandra, but require you to rebuild them because they didn’t meet the project requirements.
It’d be great if / or You’d learn & gain on our team:
- You possess solid foundation on horizontal scaling, data algorithms and knowledge of modern databases/data stacks such as DynamoDB, Redis, and/or Druid.
- You have experience with SaaS processing cloud scale data.
- You can identify relevant algorithms in the literature & bring them into production when they fit.
- You can discuss CAP theorem tradeoffs and give examples.
- You enjoy writing modern Java (we love lambdas) and prefer composition to inheritance.
