Hajoca has over 400 locations nationwide, called Profit Centers; and at the foundation of our family of businesses is a National Support Center (NSC) where Centers of Excellence are dedicated to enabling the success of our Profit Centers.

The Infrastructure Operations team in our National Support Center (NSC) is looking for a Sr Red Hat/UniVerse Administrator at their Lafayette Hill, PA office. This position is remote.

Do you have deep, hands-on experience administering Red Hat Enterprise Linux and Rocket UniVerse or another MultiValue database? Do you enjoy tuning, securing, and troubleshooting the infrastructure supporting a mission-critical ERP platform? Are you excited by the opportunity to own the SQL replication pipeline connecting Eclipse operational data to enterprise reporting and analytics? If so, then we’d like you to join our dedicated team as a Senior Red Hat / UniVerse Administrator.
About the Role:

The Senior Red Hat / UniVerse Administrator is the senior technical owner of the platform that Hajoca’s Epicor Eclipse ERP runs on — the Red Hat Enterprise Linux (RHEL) operating environment, the Rocket UniVerse MultiValue database beneath Eclipse, and the near real time SQL replication layer that feeds the enterprise data warehouse and business intelligence. This role keeps a mission critical, 24×7 distribution platform stable, secure, high performing, and highly available across production and non production environments, while ensuring that operational Eclipse data flows accurately and continuously into SQL Server for reporting and analytics.

The ideal candidate blends deep Linux systems administration with hands on MultiValue database expertise and a strong data integration mindset — someone who can tune the OS and the UniVerse database, work fluently within the Eclipse ecosystem, and own the replication pipeline that turns nested MultiValue records into clean relational data for Power BI, SSRS, and Excel.
In this role, you will:

- Automate provisioning, patching, and configuration management with Red Hat Satellite and Bash scripting to drive consistency and reduce manual effort.

- Monitor system health, forecast capacity, and proactively tune performance to sustain availability targets.

- Administer users, groups, permissions, SSH, sudo/PAM, and OS hardening in line with security policy.

- Manage, networking (interface bonding, firewalld, DNS, NTP), systemd services, logging, and scheduled jobs.

Own Rocket UniVerse / MultiValue Database Administration

- Administer Rocket UniVerse (U2) MultiValue database instances underpinning Epicor Eclipse — including accounts, files, file sizing/resizing, hashing, and record/group locks.

- Diagnose and resolve locking, contention, and session issues; tune uvconfig, phantom processes, and shared memory parameters for optimal throughput.

- Perform backups, transaction logging, and point in time recovery; validate restore procedures on a regular cadence.

- Apply MultiValue performance monitoring (e.g
