Oracle Database Administrator

GH LLC is looking for a hands-on, technically deep Oracle DBA to serve as the primary Oracle database administrator on a small but high-impact Database Services team. You will report directly to the Database Services Manager, who serves as your secondary DBA and organizational point of contact, but day-to-day database administration, performance management, and technical decision-making will be yours to own.

Our Oracle environment centers on a two-node RAC cluster with Data Guard standby, supporting core business operations. The databases are production-critical and in active use. There is meaningful work ahead - performance tuning, index and storage remediation, security hardening, a version upgrade, and a server infrastructure migration on the horizon - and we are looking for someone who can build a stable, well-managed foundation over time.

We understand that walking into a new environment takes time. You will be given the opportunity to acclimate, learn the system, and get your footing before being expected to drive major changes. Sustainable, well-understood work is the goal - not speed at the expense of stability. What You’ll Be Walking Into

Several initiatives are already underway or in planning, and you will be inheriting them in various stages of progress: Active Work

• Index rationalization and remediation on high-volume production tables
• SQL execution plan stabilization across critical workloads
• Space reclamation on production storage
• Connection pool configuration and session management review

Near-Term Roadmap

The following are planned initiatives. Prior experience with any of these is a plus, but not a requirement - what matters most is the ability to learn, plan, and execute methodically.

• Oracle patching schedule development and ongoing patch management
• Oracle version upgrade planning and execution - the upgrade will also be the gate for several downstream projects
• Oracle APEX and ORDS deployment for internal tooling - scoped to begin after the version upgrade is complete
• Lower environment refresh process design and automation
• Privilege and password security hardening across the Oracle environment
• Table partitioning evaluation and implementation for large, high-growth tables
• Documentation and operational runbook development
• Server infrastructure migration - managed by our external DBA vendor, Datavail - you will have visibility and input, and your perspective will be valued as someone who will live with the outcome

Collaboration & Projects

• Work closely with application, development, and infrastructure teams
• Coordinate with Datavail on infrastructure-layer and migration tasks

Who We’re Looking For

The right person for this role is a technician first. You are most comfortable when you are diagnosing something, fixing something, or building something - not in meetings talking about doing those things. You are methodical under pressure, you document your work, and you do not consider a problem solved until you understand why it happened.

You are not deterred by a backlog or by imperfect documentation. You have walked into environments that needed attention before, and you approached the situation as an opportunity rather than a liability. You know how to prioritize, communicate tradeoffs to non-technical stakeholders, and build trust through steady, reliable execution.

You will have real ownership here. Your recommendations will be heard, your expertise will be respected, and the work you do will have a direct and visible impact on the stability and performance of systems that matter to the business.
