We are seeking an experienced Oracle Database Administrator to take ownership of a highly available, enterprise Oracle environment that supports critical business operations. This individual will serve as the primary Oracle DBA, ensuring the stability, security, performance, and recoverability of mission-critical databases while collaborating with cross-functional teams to support ongoing business needs. The ideal candidate is a hands-on technical expert with deep Oracle 19c experience, strong troubleshooting skills, and the confidence to work independently in a fast-paced, high-availability environment., * Expert-level administration of Oracle Database 19c in large-scale, mission-critical production environments.

• Deep expertise with Oracle RAC architecture, administration, and troubleshooting (client environment runs 4 nodes).
• Hands-on Data Guard experience - must have actually executed a live failover (not just tested in a lower/non-prod environment); DR-test-level live failover experience is acceptable and valuable.
• Strong RMAN backup/recovery experience, including PITR and recovery validation.
• Advanced SQL/PL/SQL performance tuning and use of AWR/ASH/ADDM diagnostic tools.
• Linux administration with strong command-line scripting ability (Bash, Python, Perl, or similar).
• Ability to modify existing Ansible playbooks for bug fixes and small enhancements (writing from scratch not required).
• A scrappy, persistent, self-sufficient technical mindset - this person will be the company''s only Oracle resource with no onshore backup, so they must be comfortable troubleshooting independently under pressure. Strong interview focus will be on real problem-solving and troubleshooting stories.
• Strong documentation habits and ability to build/maintain operational runbooks.
• Willingness to participate in on-call rotation for a 24x7, mission-critical environment with 99.99%+ uptime requirements.
• Excellent communication skills - able to work cross-functionally with infrastructure, security, and application teams.

Nice-to-Haves:

• SQL Server administration experience (top secondary "kicker" - supports the parts catalog and related revenue-generating systems).
• MySQL and/or PostgreSQL experience (secondary kickers).
• Terraform experience may be an acceptable substitute/complement for Ansible depth - a strong technologist who can pick up adjacent tooling quickly is valued over rigid Ansible-only experience.
• Oracle GoldenGate experience (replication, zero-downtime migrations).
• Cloud/virtualization platform experience (OCI, AWS, Azure, or VMware).
• Prior experience mentoring junior DBAs or establishing operational best practices.
• Experience with Oracle Multitenant (CDB/PDB) architecture.
