Founded in 1858, Hajoca is a company based on the principles of “Service, Integrity, Reliability,” and on relationships of trust and support with teammates, customers, and suppliers. Throughout its history, Hajoca has played an active role in shaping advances in plumbing. However, we attribute our success to two simple truths;

a unique business philosophy and talented people. Hajoca is all about the people, who give us our advantage, and who will guide us successfully into the future.

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/Uni Verse 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 Uni Verse or another Multi Value 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 / Uni Verse Administrator
.

About the Role:

The Senior Red Hat / Uni Verse 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 Uni Verse Multi Value 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 Multi Value database expertise and a strong data ‑ integration mindset — someone who can tune the OS and the Uni Verse database, work fluently within the Eclipse ecosystem, and own the replication pipeline that turns nested Multi Value records into clean relational data for Power BI, SSRS, and Excel.

In this role, you will:

• Install, configure, patch, and upgrade RHEL servers (physical and virtual) that host the Eclipse/Uni Verse environment, keeping the estate on current, supported releases.

Tune the kernel, file systems (LVM/XFS), memory, and CPU for Multi Value database workloads and heavy transactional I/O.

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 Uni Verse / Multi Value Database Administration

• Administer Rocket Uni Verse (U2) Multi Value 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 Multi Value performance monitoring (e.g., Rocket MVX: Performance) to track sessions, locks, host resources, and replication health.

Use Retrie Ve/Uni Query and read Uni Verse BASIC to investigate data issues and support reporting.

• Maintain Uni Verse licensing, TLS…
