Where to Find You

Our Community Manager, Leslie Hawthorn, is hard at work to help folks create more Elasticsearch meetup groups and to help meetup organizers find more speakers. If you are interested in either effort, take a moment to let her know.

Oh yeah, we're also hiring. If you'd like us to find you for employment purposes, just drop us a note.  We care more about your skill set and passion for Elasticearch, Kibana and Logstash than where you rest your head.
