Role Summary

eSilo is a cloud data backup protection company based in Jupiter, FL with over two decades of small business and enterprise experience meeting the unique needs of the legal, healthcare, hospitality, and financial industries. We are a proud woman and minority-owned small business enterprise, and we pride ourselves in giving our customers the confidence and peace of mind to know their business is protected and secure.

We are looking for a highly motivated and capable Ubuntu system administrator (sysadmin) to assist with routine maintenance and upgrades of our internal backup systems, and can lead and execute multiple small infrastructure projects at once. You will be a key member of our backend team, with a scope of responsibility that spans multiple colocation data centers and edge locations (eSilo equipment on premises at customer sites).  

Our environment is primarily Ubuntu with ZFS, however having previous hands-on experience with a variety of operating systems, (including Windows) containerization and virtualization technologies is essential.  

Exceptional candidates may also have experience in storage management, worked with multiple backup systems, and/or have worked at a managed services provider (MSP) in the past.  

This role is best for capable technologists who are self-starters, can work independently, and love to solve complex problems. They thrive in high stress situations where there may be multiple competing priorities they must juggle, and they must be adept at balancing daily fire-fighting with long-term strategic objectives. 

In addition to your ninja tech skills, we are looking for team members who are reliable, personable, detail oriented (and who thoroughly document their work), and are able to multitask and prioritize to meet deadlines.

Come join us and do meaningful, challenging work on a dynamic close-knit team!
