As a distributed company, we believe that diversity drives our vibe! Whether you're looking to launch a new career or grow an existing one, Elastic is the type of company where you can balance great work with great life.\n\n\n* Competitive pay based on the work you do here and not your previous salary\n\n* Equity\n\n* Global minimum of 16 weeks of paid in full parental leave (moms & dads)\n\n* Generous vacation time and one week of volunteer time off\n\n* Your age is only a number.

We recently did a full-stack rewrite and moved all the old code to our new infrastructure. This means we have very little legacy cruft to deal with.\n\nHere's all the cool stuff you get to play with:\n\n\n* Large Linux / Ubuntu cluster running with the OS versioned using both Ansible and our own debian packages for software distribution.\n\n* Massive amount of data indexed from the web and social media.  We index from 5-20TB of data per month and want to expand to 100TB of data per month.\n\n* Large Cassandra install on SSD.  \n\n* SOLR / Elastic Search migration / install.  We’re experimenting with bringing this up now so it would be valuable to get your feedback.\n\n\n\n\nCompensation:\n\n\n* Salary based on experience.

Live work balance is a must.\n\n\n \n\n#Salary and compensation\n No salary data published by company so we estimated salary based on similar jobs related to JavaScript, Node, Engineer, Linux, Ops, Elasticsearch, Java, API and Cassandra jobs that are similar:\n\n $70,000 — $120,000/year\n
