Infrastructure Services

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.

• 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

• 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

• Serve as the primary Oracle DBA for a production RAC environment with Data Guard standby
• Monitor and tune performance using Oracle Enterprise Manager, AWR, ASH, and ADDM
• Manage storage, capacity planning, and tablespace health
• Maintain a proactive patching and version management schedule
• Respond to production incidents, diagnose root cause, and implement durable fixes
• Manage backup and recovery procedures in coordination with infrastructure team

• Investigate and resolve SQL plan instability using SPM baselines and SQL Profiles
• Design and maintain indexing strategies aligned with actual application usage patterns
• Tune connection pools, RAC-specific configuration, and parallel execution settings
• Identify and remediate locking, contention, and wait event issues

• Manage Oracle user accounts, roles, profiles, and least-privilege service accounts
• Enforce session controls, password policies, and audit configurations
• Partner with the development team on stored procedure design, code review, and change management
• Maintain and build out DBA documentation, runbooks, and operational standards

• Work closely with application, development, and infrastructure teams
• Coordinate with Datavail on infrastructure-layer and migration tasks
• Contribute to project planning and provide technical input on architecture decisions
• Support APEX and ORDS administration as the internal footprint grows post-upgrade

• 5+ years of hands-on Oracle DBA experience in production environments
• Strong expertise in Oracle 19c (or comparable recent version) administration
• Proven production experience with Oracle RAC and Data Guard
• Strong SQL and PL/SQL proficiency - you read and write production code, not just run scripts
• Experience…
